[103] Trinidad bitumen is best, but it has to be refined before it can
be used. This is done by cooking it with shale oil, then straining it
and decanting it, which is a troublesome and tedious process, and
there is great danger of fraud being practised. Good bitumen can be
detected by its elasticity and softness when rolled between the finger
and thumb, and also by its smell.

[106] A rule is sometimes made that York flags should be ¹⁄₂-inch
thick for every square foot of surface, but they should never be less
than 2 inches thick.

208.
[108] Sawdust 2 feet in thickness has sometimes been used, well rammed
and rolled.
[109] The town of Brighton is an instance of this. Ordinary red bricks
used to be laid as a footpath, no doubt to give a rural appearance for
the eye of the jaded Londoner, but these are giving place to more
modern materials.
CHAPTER XII.
KERBING AND CHANNELLING, ETC.
For all footpaths both urban and sub-urban a kerb of some description is
necessary to be fixed on the outside of the footpath, for the following
reasons:
(1.) It acts as a sill against which the material of which the footpath
is paved may butt.
(2.) It retains both the foundation and surface of the footpath.
(3.) Whether there is a paved channel gutter or not, a kerb is necessary
in order to finish the haunches of the roadway.
(4.) The appearance of a footpath without kerbing is very unsightly.
(5.) Unless a footpath is raised above the roadway it is liable to be
flooded.
Many materials are used for kerb, of which granite being the best is
generally used in streets where there is much traffic, as the kerb is
often subjected to severe blows from the passing vehicular traffic as
well as a grinding action from the wheels of waggons and other heavy
vehicles, especially on gradients where “hugging” the kerb acts as a
drag or break. In such cases granite, although the most expensive in the
first case, is certainly the most economical, and no other material
should ever be used.
Granite kerb varies in dimensions considerably in different localities
and according to the width of the footpaths, the wider the path the
wider should be the kerb. It should however never be of less depth than
9 inches, nor narrower than 4 inches; depth is necessary to prevent the
kerb turning over towards the channel gutter, or water table as it is
sometimes termed, and the filling in on the gutter side must also be
well rammed with a bar to prevent this. Kerb should never be in less
lengths than 3 feet, and when 8 inches and broader it is better that the
top surface should be bevelled off to conform with the slope of the
footpath, but in narrower kerbing such a practice is unnecessary, and if
carried to an extreme may even be dangerous.
The kerb should be drafted about 1 inch along both top edges and hammer
dressed about 5 inches on the face, in addition to the whole surface of
the top and for 3 inches at the back, in order that there may be a
smooth surface visible against the channel gutter, and also for the
flagging or other paving to butt fair against, besides giving a clean
appearance to the aris of kerb both inside and out.
The following section of an 8-inch granite kerb will explain this:
[Illustration]
The top surface should always be tooled or axed whenever it has worn
smooth and slippery, as a slip from a kerbstone often causes a very bad
fall to a pedestrian.
Setting kerb requires a very experienced hand, for as it is set dry
great care must be shown, or it will sink, turn slightly over, or move
even months after it has been set. In addition to this it is heavy stuff
to handle, but unless the line is accurate both as regards level and
contour, the appearance will be exceedingly bad. Of course the skillet
line and boning rods are freely used in setting kerb, but even with
these helps one mason will set kerb in a pleasing manner, whilst
another, with even more care, does not seem able to make it appear
graceful.
Deep and narrow kerb should be bedded on good clean river gravel, and
beaten into its place with hard blows from a heavy wooden setting maul
or beetle weighing not less than 50 lbs.
Broader and shallower kerb should be bedded on concrete.
In addition to granite, kerbing is also made of Endon or Yorkshire
stone, limestone, and for brick pavements a kerb specially made of the
same material is generally used; it is also, though not often in this
country, constructed of wood, old railway sleepers being used for the
purpose. In the more rural districts grass sods are used with good
effect for gravel paths.
It is difficult to estimate the cost of kerbing, as local questions must
interfere, carriage of the material and value of labour entering so
largely into the question.
Mr. Codrington[110] states that “A limestone kerb about 1 foot deep and
4 inches wide costs from 2_s._ 6_d._ to 3_s._ 6_d._ per lineal yard, and
a channel 10 inches wide by 6 inches thick rather more.
“Granite kerbs 12 inches wide by 9 inches deep, 6_s._ 6_d._ to 7_s._ per
yard run.
“Granite channel 12 inches wide by 6 inches deep, 4_s._ 6_d._ per lineal
yard.
“A channel 12 inches wide, formed of granite cubes 4 inches by 7 inches,
costs about the same.”
I have found that granite kerb 6 by 12 inches could be fixed “_in situ_”
at 3_s._ 3_d._ per yard run, and 8 by 12 inches at 4_s._ 6_d._ per
lineal yard.
Granite channelling composed of 3 courses of granite pitchers 6 by 8
inches, costing 5_s._ 6_d._ per lineal yard.
Limestone channelling 15 inches in width by 3 inches in depth, costing
3_s._ per lineal yard.
A paved channel, gutter, or water table is of the greatest use to a
roadway, besides adding greatly to its appearance. Without such a
channel the haunches of a road become sadly damaged by the wash of the
surface water, which is sometimes so extreme as to undermine the kerb
and cause it to fall out.
These channel gutters are made of different materials for macadamised
roads, granite setts laid in the direction of the gutter being the best.
A channel gutter should not be less than 18 inches wide, so that if made
with ordinary 3-inch setts, 6 courses will be necessary; they should be
bedded on gravel and well grouted in with lime or cement grouting.
Sometimes granite slabs 18 inches wide by 3 or 4 inches thick are used
and make an excellent gutter, they are however liable to tip under heavy
loads. Limestone slabs can also be used in roads of light traffic with
advantage.
In streets paved with granite setts, wood blocks or asphalte, the same
material is used for the channelling, the setts or blocks being however
bedded in line with the channel instead of transversely as in the street
itself.
The channel gutter should take the slope of the roadway and the granite
kerb should show from 3 to 5 inches above it. At paved crossings it is
well to keep them level with the kerb so that pedestrians may step off
the path on to the crossing without any drop, or if there is any water
in them at such points, it is a good plan to let the edge of the
crossing drop rather suddenly towards the kerb, so that the ordinary
stride of the pedestrian carries him on to the level.
Gulley gratings or buddle holes should be placed along the line of
channel at such intervals as may be found necessary. A great number of
different forms have been from time to time introduced for this purpose,
the objects to be considered being:
(1.) Sufficient area to carry off all the water.
(2.) Not easily choked on surface by leaves or other debris.
(3.) Sufficiency of pit to retain all sand or road detritus and prevent
it being washed into the sewer.
(4.) The least possible obstruction to the traffic.
(5.) Constructed so that the pit may easily be cleaned out.
(6.) Trapped so as to prevent the escape of sewer gas.[111]
(7.) The drain from it should be easily freed of any obstruction.
One of the best forms of gully pit is that manufactured by Messrs. Oates
and Green of Halifax, as it meets nearly all the requirements which I
have summarised as being necessary for this description of work. The
following drawing will explain itself:
[Illustration]
What is called a “buddle hole,” which is an opening under the kerb, has
much to recommend it as giving a free unobstructed waterway and at the
same time avoiding the necessity of a grating in the street itself. The
following drawing will explain the general features of this
“buddle-hole:”
[Illustration]
A great number of different descriptions and forms of gully pits are
shown in Mr. Baldwin Latham’s excellent book on sanitary engineering, to
which I refer my readers for any further information upon this subject.
[110] ‘The Maintenance of Macadamised Roads,’ by Thomas Codrington, p.
18.
[111] In many towns the gully gratings are purposely in direct
communication with the sewers, so as to act as ventilators.
CHAPTER XIII.
LIGHTING STREETS.
At the present moment the question of lighting streets by electricity is
gaining so much attention, that it must necessarily be first considered
in connection with the subject of lighting streets: but to enter fully
into all the details and comparative merits of electricity and gas as
applied to street lighting would entail more space than can be afforded
in this work. It may however be of some use, even under the present
state of uncertainty, if I attempt to condense as much information upon
this necessary part of a surveyor’s duty into as small a compass as
possible. Nor must it be forgotten that electric lighting will not
easily be adapted in old cities and towns, where, in addition to the
main streets being narrow and crooked, there are few large open spaces
suitable for intense lights, and there are numerous small courts and
alleys which require lighting, and this for a long time to come will
probably be effected with gas.[112]
Section 161 of the Public Health Act 1875 enacts as follows:
“Any urban authority may contract with any person for the supply of gas
or other means of lighting the streets, markets, and public buildings in
their district, and may provide such lamps, lamp-posts and other
materials and apparatus as they may think necessary for lighting the
same. . . .” (38 and 39 Vic. c. 55, s. 161.)
I do not propose to entertain the question of lighting where the gas
works are the property of the corporation, but only to give information
that may be of use where a contract has to be entered into between the
corporation and a company. These contracts are based nearly always upon
the length of time at which the public lamps are to be kept lighted, and
may be summarised as follows:
(1.) The public lamps are lighted from sunset to sunrise every night
throughout the year; this averages 12 hours per diem, or about 4000
hours per annum.
(2.) The public lamps are not lighted on the nights of full moon, nor
for two or three nights before and after this period; the rest of the
year they are lighted at sunset.
(3.) Similar to the preceding, except that the public lamps are not
lighted during the five nights of full moon, the night after they are
lighted for one hour and extinguished on the rising of the moon; this
lighting increases from night to night about three quarters of an hour
until the moon has entirely disappeared, when the lamps are lighted
during the whole of the night for five consecutive nights. Then again on
the appearance of the new moon the lamps are extinguished the first
night for about an hour that the moon is visible, and this extension
increases nightly about three quarters of an hour according as the moon
appears until the period of full moon, the intention being to profit by
every hour of the moon’s light.
By this arrangement the lighting is about 2000 hours per annum, instead
of 4000 hours, when it is continued throughout the night during the
whole of the year.
(4.) Sometimes, in addition to the foregoing, the lamps are not lighted
at all during the summer months.
(5.) Occasionally the public lamps are extinguished at midnight all the
year round, if not for the whole, for some portions of the district, it
being assumed that all respectable citizens being in bed, no light is
required.
(6.) In some cases every other lamp only is lighted in the summer
months, and many other similar variations for the sake of economy may be
practised.
(7.) The public lamps are sometimes supplied by gas through meters,
which is then paid for at so much per 1000 cubic feet consumed.
Of all the above methods the first is undoubtedly the most satisfactory
to the inhabitants, the urban authority, their officers, and the gas
company; it is the least likely to introduce disputes, and although
something may be saved by adopting the more parsimonious methods
enumerated, it is found in practice that the first is the best.
In drawing up an agreement with the gas company to light the public
street lamps for any length of time, the following points must be
considered.
_Hints for a Contract with a Gas Company._
The company to provide a sufficient supply of gas of the full
illuminating power and quality as provided by their Act.
Payment to be at so much per lamp, or per 1000 cubic feet consumed, or
at per hour, or whatever may be determined on.
Payment to be made by urban authority for lighting, extinguishing,
cleaning, repairing, etc., as may be agreed, such payments to be made
quarterly, or at such times as may be agreed upon.
The hours or times throughout the year during which the lamps shall be
lighted to be determined by a table, every lamp to be fully lighted
within one hour of the time named, and not extinguished before that
named for extinguishing. The consumption of the gas to be regulated and
determined by Sugg’s or Borradaile’s street lamp governors, or such
other mode as is agreed upon.
The company to keep the governors and burners in repair, and also the
lanterns, at a fixed sum per lamp per annum.
The company to light and extinguish, and keep all lanterns clean, and
all pipes, valves, etc., in repair.
The company to keep the lamp posts etc., properly painted after they are
fixed by the urban authority. Lamps may be shifted or fresh lamps
erected by the urban authority, on their paying the cost.
The company not to be compelled to supply gas to lamps which are beyond
a certain distance of their existing mains, without compensation.
A certain pressure of gas must be maintained, to be ascertained by water
gauges fixed at certain public places, or at such points as may be
determined.
Any lamps burning under size or out, shall be immediately attended to by
the company. A deduction in payment for gas by the urban authority to be
made if neglect can be proved. An arbitration clause is necessary for
this or other matters that may be disputed, and also a clause for
determining the agreement upon notice being given.
In supplying gas to the public lamps by meter, either wet or dry meters
may be employed, and these are fixed either in the lamp posts themselves
or under the footpath. Sometimes each lamp has a separate meter, but in
the generality of cases one meter fixed to a lamp gives the average of
gas consumed by ten or a dozen of its fellows at the same level, and in
the same neighbourhood. The difficulties arising from this system are:
(1.) The liability of the meters to get out of repair, especially in
times of severe frost, or by vibration of traffic.
(2.) The first cost of providing and fixing the meters, and subsequent
cost of repairs.
(3.) The trouble and cost of inspection and keeping the accounts.
And it is found that by employing either “Borradaile’s,” “Sugg’s,” or
other regulators the consumption of the gas can be readily adjusted to
consume from 3 to 6 cubic feet per hour, according to the requirements
of the situation of the lamp.[113]
Lamp posts and lanterns are of innumerable sizes, shapes, and patterns,
but the following hints in connection with them may be of some service.
The lamp must not only be ornamental by day, but useful by night.
The light must not be placed either too high or too low.
The post must not be too clumsy so as to interfere with the pedestrian
traffic, nor too fragile so as to be easily broken if driven against.
Bracket lamps have advantages in these respects, and also in the very
important one of throwing no downward shadow,[114] as well as being
cheaper.
The lantern should be made with the lightest possible amount of metal
frame compatible with sufficient strength, the angle bars should be very
narrow to avoid shadow, trap doors of perforated zinc or glass should be
provided at the bottom for the admission of the torch, and a good outlet
at the top is essential for the escape of the heated air. Flat glass is
much cheaper and easier of repair than curved. The top of the lantern
should be furnished with a reflector cover, otherwise a large percentage
of the light is lost: this is very observable on approaching a large
city, by the glare which is thrown upwards. Some hundreds of different
patterns of lanterns for street lamps have been designed from time to
time, and it is not necessary, nor have I space, to describe them.
The burners should have steatite tips and be of varying size to suit the
requirements of the locality, the regulators which I have previously
mentioned must be kept in good repair. A lever tap is indispensable with
the torch for lighting, as well as the trap door or opening in the
bottom of the lantern through which the torch is inserted.
Each public lamp post should be legibly numbered, and the surveyor
should keep a register in his office of all the public lamps in his
town.
In order to determine the distance apart of the public lamps in a
street, it must be remembered that the intensity of light is directly
proportional to the illuminating power of the light, and inversely
proportional to the square of the distance of the light, if unreflected.
For instance, the illumination of any point between lamps may be arrived
at by adding all the quotients obtained by dividing the illuminating
power in standard sperm candles of each lamp, by the square of its
distance in yards from the point.
Thus a point midway between two lamps of 15 candles each, 20 yards
apart, would be reckoned thus:
15 15
X = --- + --- = ·30
100 100
In this country, the rule has generally been adopted that public street
lamps burning 5 cube feet per hour of 15 candle gas should not be placed
at a greater distance than 60 yards apart, the average distance in most
English towns being about 40 yards.
On this question, the following interesting particulars by Monsieur
Servier will be of special interest.[115]
It appears to M. Servier that up to the present there has been too much
straining after intensity, with insufficient care for the object of
obtaining a proper quantity of light uniformly spread over the surface
of the ground. The paper in question is therefore intended in the first
place to elucidate this latter subject, so as to determine beforehand
the necessary intensity for luminous centres, gas or electric, and also
their height from the ground and distance from each other required to
produce a certain effect. With this purpose M. Servier proposes to
determine for any point of the road-surface, by the law of the squares
of the distances, the intensity of light, in terms of the Carcel
standard, which is spread at that point by one or more lights of given
power. Representing these intensities by proportional ordinates, the
extremities of these ordinates form an irregular surface, and the volume
contained between this surface and that of the roadway represents a
specific value equivalent to the total luminous intensity distributed
over the soil. In default of a better term, M. Servier calls this a
volume of _cubic Carcels_, a cubic Carcel being the intensity of a
Carcel (9·5 standard candles) multiplied by a square mètre of surface.
The different cases capable of being valued in this manner are as
follows:
1. A burner consuming 140 litres (5 cubic feet nearly), and of 1·1
Carcels (10·45 candles) illuminating power, placed at the height of 3
mètres (9 feet 6 inches). This burner gives at the foot of the
lamp-pillar a maximum intensity of 0·122 Carcel (1·159 candles), and at
10 mètres (32·8 feet) away the illuminating power is reduced to 0·01
Carcel (0·095 candle). The distance of 20 to 30 mètres kept between the
street lamps, even in the best-lighted towns, is therefore excessive,
for these should not be more than 13 mètres (14 yards) apart in order to
obtain between them the minimum illuminating power of 0·05 Carcel (0·475
candle), sufficient for enabling passengers to read.
2. The second case is that of a burner consuming 1400 litres (50 cubic
feet nearly) of gas, with an illuminating intensity of 14 Carcels (133
candles), placed at the height of 3·20 mètres; this being the class of
burner fixed in the Rue du Quatre Septembre. The intensity of light at
the foot of the lamp-pillar is 1·367 Carcels (13 candles nearly), and to
obtain the light of 0·05 Carcel (0·475 candle) already mentioned as the
least intensity enabling one to read, a point must be fixed in a circle
of 16 mètres radius from the lamp as a centre. Taking now a group of six
lamp-columns, three on each side of the street, and overlapping, as in
the Rue du Quatre Septembre, it will be found that the distribution of
light is defective. The most brilliantly lighted point at the foot of
the column has an intensity of 1·367 Carcels (13 candles), or more than
triple that of the darkest point, which has an intensity of 0·5 Carcel
(4·75 candles) at 4·58 mètres distance.
3. A lamp of 50-Carcel (475-candle) power, gas or electric, fixed at the
height of 8 mètres (26·24 feet). The illuminating intensity at the point
vertically under the light is reduced to 0·7 Carcel (6·65 candles); but
the light of 0·5 Carcel (4·75 candles) is to be found in a circle of 6
mètres radius from this point. It will therefore be observed that _the
distribution of light over the ground is better in proportion as the
luminous centre is higher_; but conversely also, _the amount of light
thrown on the ground is greater as the luminous centre is lower_. It
consequently results that the power of the light and its height should
be determined in every case with reference to the effect desired. The
method shortly described shows that, in the case of the lighting of the
Rue du Quatre Septembre, the mean amount of light per square mètre of
the roadway is 855 _décicarcel-cubes_, the best lighted parts having an
intensity of 1·62 cubic Carcels, and the darkest portions an intensity
of 0·50 cubic Carcel.
M. Servier has examined the question of lighting a street 20 mètres wide
and one or more kilomètres long, with the condition that the
illumination of the ground shall present a mean determinate quantity of
light per square mètre, or a given intensity at the darkest points. Some
interesting results are thus obtained. Thus, by substituting for the
14-Carcel (133-candle) lamps in the Rue du Quatre Septembre, burners of
50-Carcel (475-candle) power, with the condition of giving the same
intensity of 0·5 Carcel (4·75 candles) to the darkest points, a quantity
of light more considerable than before will be required. That is, a
greater number of Carcels (3000 as against 1848 per kilomètre in length)
will be necessary in the larger burners than were required in the
original smaller lamps. It is therefore imperative, in order that the
lighting shall be equally economical, that the unit of intensity--the
Carcel or candle power--shall be less costly in a lamp of 50 Carcel (or
475-candle power) than in the smaller lamps. By fixing lamps of
50-Carcel (475-candle) power in the centre of the street, instead of
along the side walks, maintaining the condition of giving the light of
0·5 Carcel (4·75 candles) in the darkest parts of the thoroughfares, it
is found that the pillars must be 8 mètres high and 20 mètres apart. The
best-lighted part of the road would then have the intensity of 1 Carcel
(9·5 candles), and would therefore be only twice as brilliantly lighted
as the darkest corner; the mean quantity light per square mètre would be
755 _décicarcel-cubes_.
Lastly, the same method of lighting has been applied to the “ordinary,”
as distinguished from the “luxurious” lighting of the public
thoroughfares, assumed to be 20 mètres wide, giving a light of 0·05
Carcel (0·475 candle) at the darkest points. With ordinary street
burners consuming 200 litres (7 cubic feet) of gas per hour, and giving
1·72-Carcel (16·34-candle) power, it is found that the lamps should be
18 mètres (20 yards nearly) apart, the burners being 3 mètres (9 feet 10
inches) high. With burners of 14-Carcel (133-candle) power placed at the
height of 3·20 mètres (10 feet 6 inches), the lamp-pillars would be 106
mètres (115 yards) apart. Or with lamps of 50-Carcel (475-candle) power
placed at a height of 8 mètres (26·24 feet), the distance between the
pillars may be increased to 270 mètres (494 yards).
In the case of electric lighting M. Servier has studied two
examples--the Jablochkoff candle, and an arc light (system not stated).
The former is credited with the illuminating power of 16 Carcels (152
candles), and is fixed at the height of 5 mètres (16 feet 3 inches), on
pillars 110 mètres (120 yards) apart. This would give a light of 0·65
Carcel (6·27 candles) at the foot of the pillar, and a minimum intensity
of 0·05 Carcel (0·475 candle) midway between the lights. The arc light
is purposely made exactly equal in computed efficiency to the larger
Siemens burner of 50 Carcels (475 candles). In the matter of expense,
however, using the data applicable to Paris, with 12-candle gas at 6_s._
6_d._ per 1000 cubic feet, M. Servier makes a striking comparison. The
cost of lighting a kilomètre of road in the “ordinary” manner last
described varies very little for the three classes of gas lamps--small,
large, and very powerful--included in the calculation, and ranges from
3·33 frs. to 3·96 frs. per hour. The cost of the same work done by the
Jablochkoff candle is estimated at about double, or 6·91 frs. per hour;
and with the arc light the cost would be 4 frs., or still higher than
with the most costly system of gas lighting, although less than the
expense of the Jablochkoff electric light.
The following table will show the particulars of different lights so
placed that persons may see to read ordinary print in any part of the
street, which may be taken as then being a well-lighted street.

It must not be lost sight of, that the illuminating power of the gas in
Paris is very low, and is thus fixed. Under a pressure of 12 hundredths
of an inch, gas burning at the rate of 4·05 cubic feet per hour (or 115
litres) shall give a light of 9·5 standard sperm candles (or a “Carcel”
lamp burning 42 grammes of pure colza oil) per hour.
The competition which has been started by the electric lighting
companies has given a great impetus to gas lighting. A large number of
improved street gas lamp burners and lanterns having been invented and
brought into general use, the following particulars with reference to
some of those which were tried in the City of Exeter may be of use as a
comparison.

Having thus far given a few facts upon lighting streets with coal gas, I
will now turn to the question of lighting them by means of electricity,
and in doing this the following points will be considered:
(1.) The motive-power to be employed in producing electricity and its
applicability for the purpose.
(2.) The description of machinery to be employed.
(3.) The value of the light produced, and its adaptability to the
requirements of any town.
(4.) The comparative cost of the electric light as compared with gas.
(1.) Whatever motive power is employed, whether water-power, steam or
gas, it is essential that it should be steady and unfailing; steady,
because the regularity and uniformity of the light depends upon the
evenness of the speed with which the power works, and unfailing, because
a stoppage means the immediate extinguishment of the lights:
electricity, unlike gas, is not stored after manufacture, but is used as
fast as it emanates from the producing power.[116]
Sensitive governors and careful bedding of the machinery greatly tend to
lessen unsteadiness, and are points of considerable importance.
(2.) The machinery consists of the dynamo machines, the conducting wires
and the lamps.
I will not here enter into the question of which is the best dynamo
machine to employ, as to discuss the merits of them all would involve a
large amount of space; but for this and other valuable information upon
the subject of electric lighting I will refer my readers to Mr. Hedges’
excellent little book entitled ‘Useful Information on Electric
Lighting,’[117] but the following points should be attended to. The
dynamo machine should be fixed in a dry place, and not be exposed to
dust or flyings, it should be kept perfectly clean, and its bearings
well oiled, its coils and conductors should be perfectly insulated, and
it should, where practicable, be fixed on an insulated bed. With regard
to the wires, the following ‘Regulations for the prevention of Fire
Risks arising from Electric Lighting,’ published by the Society of
Telegraph Engineers and of Electricians, are given in full, as they
leave nothing to be desired in the way of their careful selection and
fixing:
“(7.) Every switch or commutator used for turning the current on or off
should be constructed so that when it is moved and left to itself it
cannot permit of a permanent arc or of heating, and its stand should be
made of slate, stoneware, or some other incombustible substance.
“(8.) There should be in connection with the main circuit a safety fuse
constructed of easily fusible metal which would be melted if the current
attain any undue magnitude, and would thus cause the circuit to be
broken.
“(9.) Every part of the circuit should be so determined that the gauge
of wire to be used is properly proportioned to the currents it will have
to carry, and changes of circuit, from a larger to a smaller conductor,
should be sufficiently protected with suitable safety fuses, so that no
portion of the conductor should ever be allowed to attain a temperature
exceeding 150° F.
“N.B.--These fuses are of the very essence of safety. They should always
be enclosed in incombustible cases. Even if wires become perceptibly
warmed by the ordinary current, it is a proof that they are too small
for the work they have to do and that they ought to be replaced by
larger wires.
“(10.) Under ordinary circumstances complete metallic circuits should be
used, and the employment of gas or water pipes should in no case be
allowed.
“(11.) Where bare wire out of doors rests on insulating supports, it
should be coated with insulating material, such as india-rubber tape or
tube, for at least two feet on each side of the support.
“(12.) Bare wires passing over the tops of houses should never be less
than seven feet clear of any part of the roof, and they should
invariably be high enough, when crossing thoroughfares, to allow
fire-escapes to pass under them.
“(13.) It is most essential that the joints should be electrically and
mechanically perfect. One of the best joints is that shown in the
annexed sketches. The joint is whipped around with small wire, and the
whole mechanically united by solder.
[Illustration]
“(14.) The position of wires when underground should be efficiently
indicated, and they should be laid down so as to be easily inspected and
repaired.
“(15.) All wires used for indoor purposes should be efficiently
insulated.
“(16.) When these wires pass through roofs, floors, walls, or
partitions, or where they cross or are liable to touch metallic masses,
like iron girders or pipes, they should be thoroughly protected from
abrasion with each other, or with the metallic masses, by suitable
additional covering; and where they are liable to abrasion from any
cause or to the depredations of rats or mice, they should be efficiently
encased in some hard material.
“(17.) Where wires are put out of sight, as beneath flooring, they
should be thoroughly protected from mechanical injury, and their
position should be indicated.
“N.B.--The value of frequently testing the wires cannot be too strongly
urged. It is an operation skill in which is easily acquired and applied.
The escape of electricity cannot be detected by the sense of smell as
can gas, but it can be detected by apparatus far more certain and
delicate. Leakage not only means waste, but in the presence of moisture
it means destruction of the conductor and its insulating covering by
electric action.”
The lamps may take either the “arc” form, or the “incandescent.” The
former is produced by the electric current passing between carbon
points, and requires considerable electrical pressure; they give a light
of from 1500 to 4000 candle power; the mechanism of arc lamps has to be
of the most delicate kind to ensure the proper distance of the carbon
points being maintained. The lamps should be guarded by globes of
frosted glass, not only to prevent incandescent pieces of carbon from
falling, but to lessen the glare of the light. “Incandescent” lamps are
of small size, giving a light of from 8 to 50-candle power, which is
produced by the heating of a filament of carbon in a vacuum owing to the
resistance caused to the electric current by this contraction of the
conductor.
(3.) With regard to the value of the light produced, and its
adaptability to the requirements of any town, it will be seen on
reference to the opening of this chapter that at present considerable
doubt exists as to its adaptability for general public lighting, and as
each town varies in the length, straightness, and width of its streets,
the number of its large squares or confined courts and alleys, the
surveyor must use his own judgment as to the suitability of the light
before recommending his corporation to adopt it.
As to the value of the electric light, there can be no doubt that a most
brilliant and powerful light is produced by the voltaic arc: so
brilliant indeed, as to render it necessary to screen it nearly always
behind frosted or opalescent glass globes, the former being found to be
much the best for many reasons.
As to the photometrical value of the light, some considerable difficulty
has hitherto been experienced in obtaining accurate observations,
principally owing to the peculiar colour of the electric light, and also
from its fluctuating character; but these difficulties are being
steadily overcome, and with a photometer mounted on a light frame with
wheels, some excellent experiments have been made in the public streets
upon the comparative values of different lights.
(4.) The last and really one of the most important questions remaining
to be discussed is that of the cost of the electric light as compared
with gas.
With reference to the cost of the electric light, the following table
may be of use; it is compiled from an excellent paper on electric
lighting, by Mr. James N. Shoolbred:[118]

-------------+--------+------+-------+------+--------+----------------
As to the comparison of cost between the electric light and gas, this
has only, I believe, been properly estimated on the Thames Embankment,
London, by Sir Joseph Bazalgette, the results of whose investigations
upon this important point I shall give presently; it has, however, been
stated generally, and without contradiction, that arc lights can be
produced of about 2000 candle power, with 1 HP at a cost of from 3_d._
to 6_d._ per candle per annum of 4000 hours, gas costing from 1_s._
9_d._ to 3_s._ 6_d._ per candle according to the price of the gas.
Incandescent lamps cost 3_s._ to 4_s._ per candle per annum, as their
life is short, and only 200 candle power can be got from 1 HP.[121]
The latest investigations into the comparative cost of lighting by gas
and electricity upon the Victoria Embankment and Waterloo Bridge in
London, show that the lighting as effected by 96 gas burners for an
average of 12 hours burning all night, and 121 gas burners for 6 hours
lighted after the electric lights are put out, together with the
electric lighting 40 lights on the parapet of Embankment, and 10 on the
bridge, costs 834_l._ for the gas and 663_l._ for the electric light per
annum. Gas costing 3_s._ 2_d._ per 1000 cubic feet showed a cost of
nearly 1_s._ per hour for every 1000 candle power of light. The electric
lights cost 1¹⁄₂_d._ per light per hour, which is stated to represent
5·66 pence per 1000 candle power of light; each electric light as now
used, it is said, gives a photometric light of 265 candles, frosted
glass globes being found to pass much more light than the opalescent
globes.
These are by far the most important and reliable comparisons that have
hitherto been made, and it will be seen that the cost is in favour of
the electric light.
There is no doubt that the acme of all artificial lighting is the
prolongation of the light of day, and whether this is proposed to be
effected by electricity or gas, it should be the goal aimed at by all
who make this question their study.
[112] Since writing these lines the following letter has appeared in
the Standard and has never been refuted, which shows that electric
lighting for streets is not yet all that can be desired:
ELECTRIC LIGHTING.
_To the Editor of the_ STANDARD.
SIR,--At this time, when the question of lighting by means of
electricity is receiving so much attention, and as Chesterfield is the
only town in England whose lighting is done throughout by electricity,
it may be interesting to your readers to know what our experience has
been.
I need not detail the stages which led to our abandoning gas, and
taking up the electric light after being in darkness some months. I
may briefly state that, after going carefully into the question, we
decided to adopt the system whose praise was in everyone’s mouth a
year ago, namely, “The Brush,” and, though we were applied to by other
companies, we placed the execution of the work in the hands of the one
that we considered the most suitable--the Hammond Company. During the
negotiations of the contract, Mr. Hammond particularly pressed us not
to stipulate for incandescent lamps, as he acknowledged that their
Company were not in a position to cope with incandescent lighting for
public purposes. We, however, decided upon the town being lighted with
the Lane-Fox Incandescent Lamps, as well as the Brush Arc Lights.
After waiting many weary months for the completion of the incandescent
lighting, it is now, when declared by the contractors complete, in my
opinion a decided failure. The Lane-Fox lamps, which have been
supplied by the Brush Company, are most variable in their lighting
power; whilst some are good, others only give a feeble light instead
of a light equal to that of fifteen candles, as expected. The arc
lights are doing good service in some of the large streets, but as a
whole I think it has been fully demonstrated in a year’s trial in
Chesterfield, that the field for arc lighting is very limited indeed.
Though the tradesmen have been canvassed by the Hammond Company with a
view to introducing the arc lights into their shops and hotels, in not
one single case has the light been adopted. Indeed, it is evident to
us who have them under our eyes every night, that they are only fit
for lighting works and large, open spaces. The experience that has
been thus gained at Chesterfield at the present juncture must be of
value to all towns intending to adopt the electric light, and is my
reason for troubling you with this letter, although I believe the time
will shortly come when lighting by electricity may be advantageously
adopted, both for public and private purposes.
I am, Sir, your obedient servant,
GEO. EDWD. GEE,
_Alderman of the Borough of Chesterfield_.

[113] The Surveyor of Folkestone says: “Sugg’s self-acting regulator
is used, adjusted as nearly as may be practicable to consume 4 feet
per hour, and so very satisfactory is this apparatus that for the last
two years, after burning 7294 hours, it is found by the average meter
to have consumed 29,227 feet, as against 29,176 feet as per regulator,
being only 51 feet in excess of that which the apparatus is adjusted
to consume.” _Vide_ Ellice Clark on gas in Public Streets,

lighted by the arc system, the arrangement would probably be lamps 60
yards apart, placed alternately on either side, giving 30 lamps or
60,000 candles at a cost of about 800_l._ per annum. If lighted by
‘incandescent lamps’ we should have them placed about 30 yards apart
on both sides: that is, 120 lamps giving 2400 candles at a cost of
about 420_l._ per annum. The number of gas lamps for the same distance
might be 150, giving about 2250 candles at a cost of 300_l._ per
annum.” (‘Proceedings of the Association of Municipal and Sanitary
Engineers and Surveyors,’ vol. viii. p. 65.)
CHAPTER XIV.
STREET NAMING AND NUMBERING.
It was not until the commencement of the present century that
inconvenience was apparently felt from the want of any distinguishing
names of streets, or numbers to houses, either in London or provincial
towns; the first Act of Parliament on the subject being one passed in
the year 1819, which gave powers to vestries and district boards to put
up the names of streets, and even then for some considerable period
afterwards houses or premises were not marked with numbers, but with
distinguishing trade signs or names.
The Towns Improvement Clauses Act 1847, however, contains the following
clauses which are incorporated with the Public Health Act 1875, by the
160th section of that act:
“The commissioners shall from time to time cause the houses and
buildings in all or any of the streets[122] to be marked with numbers as
they think fit, and shall cause to be put up or painted on a conspicuous
part of some house, building or place at or near each end, corner, or
entrance of every such street the name by which such street is to be
known; and every person who destroys, pulls down, or defaces any such
number or name, or puts up any number or name different from the number
or name put up by the commissioners, shall be liable to a penalty not
exceeding 40_s._ for every such offence” (10 & 11 Vic. c. 34, sec. 64).
“The occupiers of houses and other buildings in the streets shall mark
their houses with such numbers as the commissioners approve of, and
shall renew such numbers as often as they become obliterated, or
defaced; and every such occupier who fails within one week after notice
for that purpose from the commissioners to mark his house with a number
approved of by the commissioners, or to renew such number when
obliterated, shall be liable to a penalty not exceeding 40_s._; and the
commissioners shall cause such numbers to be marked or to be renewed as
the case may require, and the expense thereof shall be repaid to them by
such occupier, and shall be recoverable as damages” (10 & 11 Vic. c. 34,
s. 65).
Some difference even now exists as to the manner in which streets are
named, there being considerable diversity in the sizes, colours, and
materials of the name plates, as well as in the spaces allowed for the
letters. The following list is given to show how this diversity existed
in the metropolis even so late as the year 1870.
Table taken from a “Memorandum by the Superintending Architect of the
Metropolitan Board of Works, relative to the enforcement of the Law
regulating the naming of Streets and numbering of Houses in the
Metropolis” (1871):
Parish A. Parish B.
Names on houses at corners of streets 237 281

„ in Minton’s china letters 2 1
„ engraved on stone 5 13
„ on porcelain plates 1 1
„ with raised letters on iron girder 1
„ on board on posts 11

And to this table are added the words “Some names are completely hidden
by vines, names given for ‘streets’ are put up as ‘roads.’” Since this
table was prepared however, the confusion has been rectified by the
energetic action of the Metropolitan Board of Works.
It is no doubt essential that for postal, telegraphic, and social
reasons there should be uniformity in the manner in which the naming and
numbering of streets is carried out, and the following particulars and
suggestions may be of use.
Names of streets should be marked up in such a manner as to be legible
both by day and lamp light, and the materials of which the name-plates
are composed should be of sufficient strength to prevent any damage
accruing to them from stone-throwing or other wilful or accidental
injury, or from the action of changes of temperature or climatic
influences of any kind, and the following list is given descriptive of
some of the modern methods of effecting this:
_Minton’s China Tiles._--These are white glazed china tiles 6 inches
square, on which either blue or black letters are burnt in, one letter
on each tile (except in the case of St. which is on one tile); they are
fixed by chasing them into walls of buildings, and setting them in
cement. They are the best description of name-plate with which I am
acquainted, their cost being only 6_d._ each, with the additional
advantages of being not easily broken, they can be removed and re-used
with facility, weather has no effect upon them, and they require no
attention whatever after they are once fixed.
_Cast-iron Plates with Embossed Letters._--These are generally painted
with a white ground, and black letters; they are liable to become
broken, and as they are fixed with screws these rust through in course
of time, when the plate may suddenly fall in a dangerous manner into the
street; another disadvantage is that they require to be painted about
once every three years.
_Painted Names on Walls of Buildings._--This method requires no special
mention; it is an economical plan and is more adopted than any other,
but the letters must be painted every three years at least, and they
are apt to be defaced if the premises are painted by the owner or
occupier.
_Enamelled Iron Plates._--These look very well, but they are apt to get
loose, and a blow from a stone will shiver them.
_Wooden or Metal Figures cut out and fastened on to Boards or against
Walls._--The same objection holds good with this method as with others
of the same description, the fastenings fail in time, and the name
disappears.
_Enamelled Glass Tablets in Street Lamps._--This is an excellent method
of recent introduction, and has many advantages. The name can be seen
very plainly either by day or night, no private premises have to be
interfered with in fixing them,[123] a uniformity of position or “where
to look” for the name of the street is secured, and there is no limit to
the number of times the name may be repeated.
Where the names of streets are placed against buildings the letters
which compose the name should not be less than 4 inches in height by 2
inches in breadth, with a space between each letter of not less than 1
inch; a light colour should always where practicable be used for the
back ground, and black or blue for the letters. One great objection to
painted letters is that they must be frequently repainted, and in order
to do this, ladders have to be raised against the building, which the
occupiers naturally object to without previous notice: it is always very
annoying to any citizen to have the head of a painter appearing outside
his bed-room window at any time, and more especially at an inconvenient
hour in the morning.
In selecting names for streets it is very important that they should not
be duplicated in a town, and also that there should be some sense in
their nomenclature; generally some local association can be found with
a family or historical name which is suitable for the street. Nothing is
more ridiculous than to see such names as Bath Street or York Road given
to streets which have as much association with such places as with
Jericho.
The street having been properly and conspicuously named, the next point
to consider is that of the manner in which it shall be numbered, there
being three methods in vogue by which this can be effected.
(1.) By allotting even numbers on one side of the street and odd numbers
on the other side.
(2.) By allotting consecutive numbers up one side of the street, and
down the other side.
(3.) By allotting corresponding numbers to both sides of the street,
which are distinguished by a prefix of north and south, or east and
west, as the case may require.
The first is by far the best method to pursue, for the following
reasons:
If the street is ever extended after being numbered, the sequence is in
no way disturbed. By this method any house can be more easily found, as
on reference to a directory it will at once be seen at which end of the
street it is situated. If the second method had been adopted this would
be impossible, except for the first few numbers, and where a street is
of considerable length with branch streets running into it this is of
the greatest importance. It is the best method also for the Post-Office
officials, as it facilitates the district sorting of the letters.
Giving each side of the street distinctive prefixes to its name, such as
north and south, &c., is evidently a bad plan, and leads to much
confusion.
In allotting numbers to premises in a street, if it has been already
numbered care should be taken to disturb existing numbers as little as
possible, for an altered number involves considerable expense as well as
inconvenience to the occupier of business or trade premises, owing to
the necessity of altering bill heads, letter paper, &c., and sometimes
even considerable trouble and expense in order to secure the validity of
the title.
Avoid numbering from right to left, and take care to allot sufficient
numbers to vacant spaces which may eventually be built upon, and to do
this the length of frontage may be divided into such lengths as (in the
surveyor’s judgment) will represent the new frontages. In any case it is
better to have too many numbers in a street than too few, and large
premises, and any public or other buildings which may be removed, and
other buildings substituted should have numbers allotted to them,
although it will not be necessary to serve the notices to have them
affixed. Most large shops prefer to have more than one number, although
I have heard the rather far-fetched contention urged, that more than one
number means extra rating.
Considerable care must be exercised to ensure that no separate premises
are passed over in allotting the numbers, often only a door or side
passage denoting the existence of another claimant for a number. Nothing
looks worse in a freshly numbered street than to see such numbers as 37A
or 96¹⁄₂ placed upon premises that should have had a distinct numeral,
and thus showing that they must have been left out.
The manner in which streets are numbered is generally as follows:
The town surveyor or one of his assistants walks through the street, and
with a piece of chalk legibly marks each house with its correct number,
taking care to observe the precautions I have enumerated; having done
this throughout its entire length, these numbers must be entered in a
book with the name of the occupier written opposite to the number. Upon
returning to the office the surveyor must then fill up and serve the
necessary notice upon each of these occupiers, the following being given
as a specimen of such notice:

It has been reported to the Town Council that you have neglected to
obliterate the old number of your premises, No.

The duplication of numbers in the same street was found to be the
occasion of so much inconvenience, that the Council were obliged to
re-number the street in question, and it is manifest that if a number
allotted to another house is retained by you, the inconvenience sought
to be removed will still remain.
I am therefore instructed to inform you that unless the old number of
your premises is obliterated within seven days from the date of this
notice, proceedings will be taken against you for the recovery of the
penalty incurred.

Of course, if nothing is done after service of this second notice, it
only remains to summon the offender as provided by the sections of the
Act, which I have given in the early part of this chapter.
[122] “Street” includes any highway (not being a turnpike road), and
any public bridge (not being a county bridge), and any road, lane,
footway, square, court, alley, or passage, whether a thoroughfare or
not. (38 & 39 Vic. c. 55, s. 4.)
[123] The law apparently gives the Sanitary Authority power to fix
names of streets against any premises they may choose, without first
applying for or obtaining any consent from either the occupier or
owner of such premises. (_Vide_ 10 & 11 Vic. c. 34, s. 64.)
[124] If the premises have no existing number, these words can be left
out.
CHAPTER XV.
BREAKING UP STREETS.
In nearly every city and town of the United Kingdom, except those where
the gas and water undertakings are the property of the urban authority,
the town surveyor is constantly annoyed by having some portions of his
streets broken up and greatly damaged by the action of the gas or water
companies of the district.
With regard to the lasting character of the damage caused to the street
by this disturbance of its surface, I shall have something to say in
this chapter, but it is first necessary to see what legal powers the
companies have to break up the streets, and what powers the surveyor has
to enforce the work being properly carried out.
It will be found that the sections bearing upon this point are almost
precisely similar in their wording in the following Acts:
“The Gas Works Clauses Act 1847” (10 & 11 Vic. c. 15).
“The Water Works Clauses Act 1847” (10 & 11 Vic. c. 17).
“The Electric Lighting Act 1882” (45 & 46 Vic. c. 56).
but with regard to the powers of the Government to lay telegraph and
telephone wires, &c., the clauses are different, and are contained in,
“The Telegraphs Act 1863” (26 & 27 Vic. c. 112).
As the clauses on this subject of “the Water Works Clauses Act” are
those which are incorporated with the Public Health Act 1875, I shall
select the sections from that Act, the first of importance being as
follows:
“The undertakers, under such superintendence as is hereinafter
specified, may open and break up the soil and pavement of the several
streets and bridges within the limits of the special Act, and may open
and break up any sewers, drains, or tunnels, within or under such
streets or bridges, and lay down and place within the same limits pipes,
conduits, service pipes, and other works, and engines, and from time to
time repair, alter, or remove the same, and for the purposes aforesaid
remove and use all earth and materials in and under such streets and
bridges, and do all other acts which the undertakers shall from time to
time deem necessary for supplying _water_[125] to the inhabitants of the
district included within the said limits; doing as little damage as can
be[126] in the execution of the powers hereby or by the special Act
granted, and making compensation for any damage which may be done in the
execution of such powers” (10 & 11 Vic. c. 17 s. 28).
The next clause deals only with the powers of laying pipes, &c., in
private property, and here it will be well to remark that if the water
undertaking is in the hands of the urban authority they have much more
power of entry for these purposes than companies possess (_Vide_ ss. 16,
18, 32, and 54, 38 & 39 Vic. c. 55), but this is a matter which does not
affect the questions dealt with in this chapter.
The next clause is upon the subject of giving the necessary notices, and
is as follows:
“Before the undertakers[127] open or break up any street, bridge, sewer,
drain, or tunnel, they shall give to the persons under whose control or
management the same may be, or to their clerk, surveyor, or other
officer, notice in writing of their intention to open or break up the
same, not less than three clear days before beginning such work, except
in cases of emergency arising from defects in any of the pipes or other
works, and then so soon as is possible after the beginning of the work
or the necessity for the same shall have arisen” (10 & 11 Vic. c. 17, s.
30).
The next clause is of great importance, as it gives the surveyor the
necessary powers to dictate the manner in which the interference with
his streets is to be conducted.
“No such street, bridge, sewer, drain, or tunnel shall, except in the
cases of emergency aforesaid, be opened or broken up except under the
superintendence of the persons having the control or management thereof,
or of their officer, and according to such plan[128] as shall be
approved of by such persons or their officer, or in case of any
difference respecting such plan, as shall be determined by two justices;
and such justices may, on the application of the persons having the
control or management of any such sewer or drain, or their officer,
require the undertakers to make such temporary or other works as they
may think necessary for guarding against any interruption of the
drainage during the execution of any works which interfere with any such
sewer or drain. Provided always, that if the persons having such control
or management as aforesaid, and their officer fail to attend at the time
fixed for the opening of any such street, bridge, sewer, drain, or
tunnel, after having such notice of the intention of the undertakers as
aforesaid, or shall not propose any plan for breaking up or opening the
same, or shall refuse or neglect to superintend the operation, the
undertakers may perform the work specified in such notice without the
superintendence of such persons or their officer” (10 & 11 Vic. c. 17,
s. 31).
There are several points to which it is necessary to draw attention
whilst considering the above clause. I am afraid that the “attendance”
of the surveyor “at the time fixed for the opening” or even of one of
his assistants could not always be managed, nor would it be practicable
to prepare a “plan” for every opening that might be made by a gas or
water company for new services, leaks in mains, &c.; but where it is
proposed to carry out any extensive works, such as laying a considerable
length of new main or removing an old one, it is certainly necessary
that there should be some “plan” of the manner in which such work is
proposed to be carried out by the company.
On referring to the clause it is evident that the first “plan” mentioned
must be prepared by and on behalf of the company proposing to carry out
the work, and this plan must show the exact position on each street of
the proposed excavations, and their depth, &c., which “shall be approved
of by such persons (having the control of the streets) or their
officer,” their officer really being the surveyor.
Lower down in the clause another “plan” is referred to in the following
words: “or shall not propose any plan for breaking up or opening the
same.” This plan, or more correctly speaking, a specification of the
manner in which the company shall proceed with the work, must be
prepared by the surveyor, and if it meets with the approval of his
corporation it can be enforced.
In order to assist town surveyors who may be required to act under this
clause, I now give a verbatim copy of a “plan” or specification under
which I compelled a gas company to work after they had given me the
usual statutory notice of their intention to break up certain
macadamised streets for the purpose of removing some disused mains.
_Plan of the manner in which the Gas Light and Coke
Company shall take up and remove the old mains in street,
commencing at or near street._
A trench to be excavated of not greater width than inches and of no
greater length than feet at a time.
Great care must be taken to keep the top facing metal separate from the
lower formation of the roadway, so that they may not become mixed
together; no metal is on any account to be removed from the street.
The mains must be taken up with all possible speed and instantly
conveyed away, without being allowed to remain at the sides of the
streets.[129]
The trench to be then at once filled in, care being taken to replace all
the materials of which the roadway is formed in their proper positions.
All extra filling in that may be required owing to the removal of the
mains shall be done on the surface with the best stone, broken
so as to pass all ways through a ring of 2¹⁄₂ inches internal diameter,
the top of the trench being always kept flush with the surface contour
of the roadway. No earth, rubbish, or other material shall be allowed to
be brought on to the ground by the gas company for the purpose of
filling in, nor shall any material of any kind be allowed to be brought
from any other excavations that may be being made by the gas company in
other parts of the town for the purpose of laying or removing mains.
The filling in to be done in the proportion of one man filling to two
men ramming with punners of not less weight than lbs. each. During
dry weather a plentiful supply of water must be allowed to run into the
trench whilst the filling in is in progress, for the purpose of
consolidating the ground.
The traffic must not in any case be impeded, and planks must be placed
across the excavations, where necessary, for the convenience of foot
passengers.
The work shall if necessary be suspended on market days, or any other
days that the surveyor may deem proper for the convenience of the
public.
* * * * *
The next clause of the Act deals with the manner in which the companies
shall reinstate and make good the road or pavement, and is as follows:
“When the undertakers open or break up the road or pavement of any such
street, or bridge, or any sewer, drain, or tunnel, they shall with all
convenient speed complete the work for which the same shall be broken
up, and fill in the ground and reinstate and make good the road or
pavement, or the sewer, drain, or tunnel so opened or broken up, and
carry away the rubbish occasioned thereby; and shall at all times whilst
any road or pavement shall be so opened or broken up cause the same to
be fenced and guarded, and shall cause a light sufficient for the
warning of passengers to be set up, and kept there against every night
during which such road or pavement shall be continued open or broken up,
and shall after replacing and making good the road or pavement which
shall have been so broken up, keep the same in good repair for three
months thereafter, and such further time, if any, not being more than
twelve months in the whole, as the soil so broken up shall continue to
subside” (10 & 11 Vic. c. 17, s. 32).
The conditions embodied in the above clause are easier written than
carried out.
It is well known that a trench cut longitudinally through a street takes
a very long time to heal. Asphalte shows it the least if there is a good
backing of concrete, but all other pavements suffer considerably in the
process, as it is almost impossible to maintain their strict contour,
and with macadamised roadways the result is simply disastrous.
Opening a macadamised roadway does it more harm than the heaviest and
most persistent traffic, and it is surprising for what a length of time
the surface will show the treatment it has received.
It is unfortunately the practice generally for the men in the employ of
a gas or water company, after laying a pipe, to try and ram into the
trench all the material they have removed, without allowing for the
cubical contents taken up by the pipe, or if they do condescend to cart
anything away it is generally the metal, which they think will come in
nicely for the repairs of the trench during their liability for such
repairs. What ought to be done is that no filling of ordinary earth,
&c., should be allowed to come within at least six inches of the top of
the trench, which should then be filled in with good road metal, and as
this wears down it should be brought up to the proper level with more
metal. In the former plan a hump is seen over the trench, and this hump
is a mass of mixed dirt and road-metal for which there is no cure but
its entire removal to a depth of at least six inches, and the
substitution of good clean road-metal, which would have been the best
and most economical plan in the first place.
The clauses following those I have quoted are “penalty clauses” for
non-compliance with the provisions of the Act, and need not be here
given, but there is one more clause of the Water Works Clauses Act 1847,
dealing with the powers of private individuals to break up streets for
the purpose of laying service pipes, which it is necessary to give _in
extenso_.
On the question of similar powers to private individuals to break up
streets for drains, &c., I shall speak later on in this chapter:
“Any such owner or occupier may open or break up so much of the pavement
of any street as shall be between the pipe of the undertakers and his
house, building or premises, and any sewer or drain therein, for any
such purpose as aforesaid, doing as little damage as may be and making
compensation for any damage done in the execution of any such work;
provided always, that every such owner or occupier desiring to break up
the pavement of any street or any sewer or drain therein, shall be
subject to the same necessity of giving previous notice, and shall be
subject to the same control, restrictions, and obligations in and during
the time of breaking up the same, and also reinstating the same, and to
the same penalties for any delay in regard thereto, as the undertakers
are subject to by virtue of this or the special Act” (10 & 11 Vic. c.
17, s. 52).
It would also seem that the _consent_ of the urban authority must be
obtained (as well as notice given to them) before a street is broken up
(38 & 39 Vic. c. 55, s. 149).
Very often, however, the companies prefer to execute all this work
themselves, as they do not like anyone else to interfere with their
mains or put in services which may be unfitted for the purpose;
consequently they give the necessary notices, execute the work
themselves, and charge the owner or occupier with the expense.
The powers under which streets are broken up for telegraphic or
telephonic purposes are, as I have previously stated, contained in the
“Telegraphs Act 1863,” the following being the clauses which refer to
this subject:
“The company shall not place a telegraph under any street within the
limits of the district over which the authority of the Metropolitan
Board of Works extends, or of any city or municipal borough or town
corporate, or of any town having a population of thirty thousand
inhabitants or upwards (according to the latest census), except with the
consent of the bodies having the control of the streets within such
respective limits” (26 & 27 Vic. c. 112, s. 9).
“Where the company has obtained consent to the placing, or by virtue of
the powers of the company under this Act intends to proceed with the
placing of a telegraph under a street or public road, the depth, course
and position at and in which the same is to be placed shall be settled
between the company and the following bodies:
“The body having the control of the street or public road.
“The body having the control of the sewerage or drainage thereunder.
“But if such settlement is not come to with any such body, the following
provisions shall take effect:
“(1.) The company may give to such body a notice specifying the depth,
course and position which the company desires.
“(2.) If the body to whom such notice is given does not, within 28 days
after the giving of such notice, give to the company a counter-notice
objecting to the proposal of the company, and specifying the depth,
course and position which such body desires, they shall be deemed to
have agreed to the proposal of the company.
“(3.) In the event of ultimate difference between the company and such
body, the depth, course and position shall be determined in England or
Ireland by two Justices, and in Scotland by two Justices or the Sheriff”
(26 & 27 Vic. c. 112, s. 10).
“Subject to any special stipulations made with a company by the body
having the control of a street or public road, and to any
determinations, orders, or directions of the Justices, or Sheriff, as
aforesaid, where the company proceeds to open or break up a street or
public road, the following provisions shall take effect.
“(1.) The company shall give to the bodies between whom respectively and
the company the depth, course and position of a telegraph under such
street or public road are hereinbefore required to be settled or
determined, notice of their intention to open or break up such street or
public road, specifying the time at which they will begin to do so, such
notice to be given in the case of an underground work ten days at least,
and in the case of an above-ground work five days at least before the
commencement of the work, except in case of emergency, in which case
notice of the work proposed shall be given as soon as may be after the
commencement thereof.
“(2.) The company shall not (save in case of emergency) open or break up
any street or public road except under the superintendence of the bodies
to whom respectively notice is by the present section required to be
given, unless such bodies respectively refuse or neglect to give such
superintendence at the time specified in the notice for the commencement
of the work or discontinue the same during the work.
“(3.) The company shall pay all reasonable expenses to which such bodies
respectively may be put on account of such superintendence” (26 & 27
Vic. c. 112, s. 17).
It will be seen by the above section that the time required before the
work is commenced after service of the notice is considerably longer
than that for gas or water mains or for electric lighting wires, and
subsection 3 authorises a payment for the services of the surveyor or
other officer attending to superintend the work, which is not the case
in the other Acts.
The next clauses are as follows:
“Subject to any such special stipulations as aforesaid, after the
company has opened or broken up a street or public road they shall be
under the following further obligations:
“(1.) They shall with all convenient speed complete the work on account
of which they opened or broke up the same, and fill in the ground and
make good the surface, and generally restore the street or public road
to as good a condition as that in which it was before being opened or
broken up, and carry away all rubbish occasioned thereby:
“(2.) They shall in the meantime cause the place where the street or
public road is opened or broken up to be fenced and watched, and to be
properly lighted at night:
“(3.) They shall pay all reasonable expenses of keeping the street or
public road in good repair for six months after the same is restored,
so far as such expenses may be increased by such opening or breaking up”
. . . (26 & 27 Vic. c. 112, s. 18).
“Whenever the permanent surface or soil of any street or public road is
broken up or opened by the company it shall be lawful for the body
having the control of the street or road, in case they think it
expedient so to do, to fill in the ground, and to make good the pavement
or surface or soil so broken up or opened, and to carry away the rubbish
occasioned thereby, instead of permitting such work to be done by the
company; and the cost and expenses of filling in such ground and making
good the pavement or soil so broken up or opened, shall be repaid on
demand to the body having the control of the street or road by the
company, and in default thereof may be recovered by the body having the
control of the street or road from the company, as a penalty is or may
be recoverable from the company” (26 & 27 Vic. c. 112, s. 19).
“The company shall not stop or impede traffic in any street or public
road, or into or out of any street or public road, further than is
necessary for the proper execution of their works. They shall not close
against traffic more than one third in width of any street or public
road or of any way opening into any street or public road at one time;
and in case two-thirds of such street or road are not wide enough to
allow two carriages to pass each other, they shall not occupy with their
works at one time more than fifty yards in length of the one-third
thereof except with the special consent of the body having the control
thereof” (26 & 27 Vic. c. 112, s. 20).
It will be seen that these are much more elaborate clauses, restricting
the rights of the telegraph companies than those of the gas and water
companies, &c., and as the Telegraphs Act containing these strict
clauses was passed in the year 1863 and the Water Works Clauses Act in
1847, it is fair to assume that the clauses of the Telegraphs Act 1863
were framed to meet certain objections to these clauses and upon
experience of their working, and are consequently better and more
adapted for the case in point.
To obviate all the difficulties and complications arising out of this
constant breaking up of streets, with the attendant inconvenience to the
public and damage to the surfaces of the roadways, it was suggested many
years ago that subways should be constructed under the surface of the
principal streets, in which should be placed all the gas and water mains
then existing.
There is no doubt that there are many advantages in this plan as well as
some disadvantages. It must be recollected that probably the subways
would have been constructed of sufficient capability to carry all the
mains and wires then existing, with a margin for future extensions of
size, but when we see the enormous growth of many towns, notably that of
the metropolis, and the consequent increase necessary in the number and
diameters of the mains, it is to be feared that sufficient space would
not have been left, and competition between rival gas and water
companies might consequently have been crippled.
Still there would be great convenience in many respects if all water and
gas mains, telegraph and telephone wires could be carried in subways, as
they would be easily accessible for repairs, and hidden leaks would be
unknown. With regard to the one great objection so constantly urged,
that in the case of a leaky gas main or service a most terrible and
damaging explosion might take place, it is true that this is a very
grave and serious objection, but it must also be recollected that
although this danger may be enhanced by the necessarily solid masonry of
which the subway is constructed, still there would be every precaution
taken to prevent leakage of gas, and in the present system liability to
explosion is not altogether remote. In Percy Street, Tottenham Court
Road, only a year or two ago, there was a terrible explosion in
trenches and mains which had become full of gas and atmospheric air in
the proportions of one volume of gas to fifteen volumes of air, and if
gas mains were laid in subways greater precautions would no doubt be
taken.
There would be also great danger in conveying the wires used for
electric lighting purposes in these subways, as they might fuse and thus
cause danger, and at all events they would have some considerably
disturbing influence upon the wires of the telegraph and telephone
systems, if laid too near.
I will now pass on to consider the powers of individuals to break the
surface of public streets for the purpose of putting new drains to their
premises or of repairing existing drains.
With regard to the former question I have given full particulars with
regard to new drains or connections with sewers in the chapter upon
“house drainage,” but with regard to the latter question it will be
necessary to make a few remarks.
There is no doubt that the public streets vest in the urban authority,
and it is contended that the following clause of the Public Health Act
1875 prevents any person from breaking up any street without their
permission, although it is sometimes questioned whether the words
“wilfully displaces” do not mean the doing of an illegal act, such as
taking up a stone in a street to annoy or injure a neighbour or from
sheer mischief, rather than that of a legal act for a proper purpose;
the clause in question is as follows:
“All streets being or which at any time become highways repairable by
the inhabitants at large within any urban district, and the pavement
stones and other materials thereof and all building implements and other
things provided for the purposes thereof, shall vest in and be under the
control of the urban authority. . . . Any person who without the consent
of the urban authority wilfully displaces or takes up, or who injures
the pavement, stones, materials, fences or posts of or the trees in any
such street, shall be liable to a penalty not exceeding five shillings
for every square foot of pavement, stones or other materials so
displaced taken up or injured; he shall also be liable in the case of
any injury to trees to pay to the local authority such amount of
compensation as the court may award” (38 & 39 Vic. c. 55, s. 149).
Even, however, granting that application must be made before any
individual can break up a street, the urban authority would not be
likely to withhold their consent if it was for a legitimate purpose, and
having disturbed the street, a person must light and guard the opening,
and the “hole,” as it is called in the clauses following must be “filled
up or otherwise made secure;” but it is very doubtful if he can be
called upon to keep the surface of the road in repair for any length of
time, as can be done in the case of water and gas companies, &c.; the
following are the clauses in question:
“When any building materials, rubbish or other things are laid or any
hole made in any of the streets, whether the same be done by order of
the commissioners or not, the person causing such materials or other
things to be so laid or such hole to be made, shall at his own expense
cause a sufficient light to be fixed in a proper place upon or near the
same, and continue such light every night from sun-setting to sun-rising
while such materials or hole remain. And such person shall at his own
expense cause such materials or other things and such hole to be
sufficiently fenced and enclosed until such materials or other things
are removed or the hole filled up or otherwise made secure” . . . (10 &
11 Vic. c. 34, s. 81).
“In no case shall any such building materials or other things or such
hole be allowed to remain for any unnecessary time.” . . . (10 & 11 Vic.
c. 34, s. 82).
“If any building, or hole, or any other place near any street be for
want of sufficient repair, protection or inclosure, dangerous to the
passengers along such street, the commissioners shall cause the same to
be repaired, protected, or inclosed, so as to prevent danger therefrom,
and the expenses of such repair, protection, or inclosure shall be
repaid to the commissioners by the owner of the premises so repaired,
protected or inclosed, and shall be recoverable from him as damages” (10
& 11 Vic. c. 34, s. 83).
These three sections are incorporated in the Public Health Act 1875, by
38 & 39 Vic. c. 55, s. 160, and the last clause undoubtedly gives power
to the urban authority to repair a “hole” which for want of “sufficient
repair” is “dangerous to passengers” but not otherwise, in however
unsightly a manner the trench may have been repaired.
The result of this uncertainty has been that a great many towns have
inserted in their private improvement Acts, clauses making it compulsory
upon all persons to give them from 3 to 7 days’ notice of their
intention to break up the streets, specifying the manner in which the
work shall be done, and also compelling them to deposit a sum of money
in order to secure that the repairs of the street are properly
executed.[130] A better method than this is to insert in any private
improvement Act a clause giving powers to the urban authority to execute
all drain-work themselves and charge it upon the owners of the property,
thus ensuring that any interference with the surface of the street shall
be done in a proper manner by men accustomed to the work, and also that
the drain itself shall be of perfect workmanship.
Where the town surveyor has no private improvement Act dealing with this
question, it is well to frame some regulations as to the manner in which
the notice of intention to break up the surface of the street shall be
given to him by the person intending to do the work, and if possible to
obtain a deposit of a few shillings as a guarantee that the surface of
the street shall be kept in something like decent repair. Although this
may not be strictly legal, it is a very universal practice amongst town
surveyors.
The following forms of notices are given as specimens of the description
of notice now in use, and are copied verbatim from those which are now
enforced in a very large borough in this country:

_Borough Surveyor._
NOTE.--If the surface repairs should cost less than the deposited sum,
the balance will be returned to you by the accountant, who will notify
you of the fact.
Notice must be given to the Building Inspector when the work is ready
for inspection, and no drainage work must be covered up until it has
been examined by the Inspector.
It may be well to add to this authority to break up the streets, the
following words--
“This authority may be revoked at any time if found necessary, and it
does not in any way relieve the person to whom it is granted from any
liabilities he may incur in respect of accidents from anything done in
pursuance thereof.”
In some towns the following custom prevails in regard to this question.
The person desirous of opening the street for the execution of any work
has to apply to the surveyor for a licence, and at the same time deposit
a sum sufficient to cover the expense of the work, such sum being
estimated and fixed by the surveyor. The corporation then supply one
labourer whilst the job is in hand, who, whilst working, takes care that
the soil is properly rammed and the surface made good; a mason is also
supplied to make any drainage or sewer connections. The deposit is kept
for about 3 months, and the cost of the labourer and mason, and of any
subsequent making good the surface of the street, is then deducted, and
the balance returned to the person who made the deposit.
This arrangement seems an excellent plan, and is said to work remarkably
well where it is in vogue, but whether it is strictly legal is open to
considerable question.
[125] Or gas or electricity, as the case may be.
[126] These words apply only to the manner of doing the work, not to
alternative ways of doing it. (_Vide_ ‘Fitzgerald’s Public Health and
Local Government Act, 1875,’ 3rd edition, p. 45.)
[127] In the “Electric Lighting Act 1882,” the words “proceed to” have
been inserted before the word open, which is an obvious improvement.
[128] It is incumbent upon the undertakers intending to break up a
road to communicate beforehand their proposed plan or method of
executing the work to the road authority, and this in a sufficient
manner to enable the road authority to judge whether what is proposed
ought to be done without modification. The plan should, therefore,
show the position on the road of the proposed excavation, and its
depth. (Edgware Highway Board _v._ Colne Valley Water Company, 46 L.
J. ch. 889.)
[129] This precaution was necessary, as the smell of the old mains was
naturally very offensive and a nuisance.
[130] In some towns it is the practice to give the builder a junction
pipe or block for nothing, thus ensuring his calling to give notice,
but this is only successful in the case of new attachments to sewers,
in which case the law is much more strict.
CHAPTER XVI.
OBSTRUCTIONS IN STREETS.
For convenience, I propose to treat in this chapter some subjects which,
strictly speaking, do not come under the head of “obstructions,” but
they are all questions which have to be considered by the town surveyor;
temporary obstructions and other offences with which it is the province
of the police to deal are omitted.
The following subjects will therefore be discussed:
(1.) Improving the line of frontages of streets.
(2.) Removing projections.
(3.) Doors and gates opening outwards.
(4.) Vault or cellar coverings.
(5.) Rain-water shutes and down-pipes.
(6.) Blinds or awnings over footpaths.
(7.) Trees over-hanging roadways.
(8.) Surface water from private premises running over footpaths.
(9.) Hoardings and scaffolds.
(10.) Dangerous buildings.
(1.) _Improving the Line of Frontages of Streets._--By the Towns
Improvement Clauses Act 1847, certain powers were granted which enabled
the commissioners to agree with owners of property to set back for the
purpose of widening any street,[131] but this was often found to be
difficult and wearisome of accomplishment, consequently in the Public
Health Act 1875, the following important clause bearing upon this point
was inserted.
“Where any house or building situated in any street in an urban
district, or the front thereof, has been taken down in order to be
rebuilt or altered, the urban authority may prescribe the line in which
any house or building, or the front thereof, to be built or rebuilt in
the same situation shall be erected, and such house or building or the
front thereof shall be erected in accordance therewith. The urban
authority shall pay or tender compensation to the owner or other person
immediately interested in such house or building for any loss or damage
he may sustain in consequence of his house or building being set back or
forward, the amount of such compensation in case of dispute to be
settled by arbitration in manner provided by this Act” (38 & 39 Vic. c.
55, s. 155).
This clause gives an excellent power to the sanitary authority,
especially in older towns, to lay down improved building lines upon the
plan of their town, and thus set back the line of buildings as
opportunity offers.
In assessing the value of compensation to be paid to the owner for
setting back his property, the following points should be considered:
(1.) The value of the area of the land given up to the public.
(2.) The loss of available and useful space to the premises.
(3.) If any use is made by the owner of the land given up to the public
by constructing cellars underneath, the amount of compensation should be
less.
(4.) The amount the owner will have to expend to make good the sides of
the neighbouring premises thus exposed by his setting back must be
considered.
A surveyor should be very careful to recollect if any building line has
been laid down in any street when the plans of new buildings are
deposited with him for approval. If these plans are approved without any
notice being given to the owner to set back, it is questionable whether
he can afterwards be called upon to do so.[132]
(2.) _Removing Projections of Buildings._--The Towns Improvement Clauses
Act 1847 made provision for setting back any house or building, or any
part which projected beyond the regular line of street when taken down,
on payment of compensation,[133] and this and the following sections
were incorporated in the general Public Health Act 1875.[134]
“The commissioners may give notice to the occupier[135] of any house or
building to remove or alter any porch, shed, projecting window, step,
cellar, cellar-door, or window, sign, sign-post, sign-iron, show-board,
window shutter, wall, gate, or fence, or any other obstruction or
projection erected or placed after the passing of the special Act,
against or in front of any house or building within the limits of the
special Act, and which is an obstruction to the safe and convenient
passage along any street, and such occupier shall within fourteen days
after the service of such notice upon him, remove such obstruction or
alter the same in such manner as shall have been directed by the
commissioners, and in default thereof shall be liable to a penalty not
exceeding forty shillings; and the commissioners in such case may remove
such obstruction or projection, and the expense of such removal shall be
paid by the occupier so making default, and shall be recoverable as
damages; provided always, that except in the case in which such
obstructions or projections were made or put up by the occupier, such
occupier shall be entitled to deduct the expense of removing the same
from the rent payable by him to the owner of the house or building.”
The wall of a garden in front of a house, and shrubs in the garden,
which encroach on the street, come within the words “any other
obstruction” in this section.[136]
It is doubtful, however, if trade signs projecting at such a height as
not to be “an obstruction to the safe and convenient passage along any
street” can be removed under this section, however unsightly they may
be, nor does it appear that flag poles or flags can be ordered to be
removed when at such a height as to cause no obstruction.
The following clause, however, of the Public Health Act 1875 affects the
question of new projections much more closely.
“It shall not be lawful in any urban district, without the written
consent of the urban authority, to bring forward any house or building
forming part of any street or any part thereof, beyond the front wall of
the house or building on either side thereof, nor to build any addition
thereto beyond the front of the house or building on either side of the
same. Any person offending against this enactment shall be liable to a
penalty not exceeding 40_s._ for every day during which the offence is
continued after written notice in this behalf from the urban authority”
(38 & 39 Vic. c. 55, s. 156).
Here some difficulty is frequently experienced as to the question if the
building has really been brought beyond the common line of neighbouring
buildings, especially where the houses are detached; but it is
apparently left to the tribunal before whom the case is heard to decide
this point, and the surveyor can only give his evidence, as in many
other cases, to the best of his ability and knowledge, and trust to
obtaining a verdict in his favour.
With regard to obstructions erected before the passing of the special
Act, the commissioners may cause the same to be removed or altered as
they think fit--
“Provided that they give notice of such intended removal or alteration
to the occupier[137] of the house or building against or in front of
which such alteration or removal is begun; and if such obstructions or
projections shall have been lawfully made, they shall make reasonable
compensation to every person who suffers damage by such removal or
alteration.”[138]
Here the words “_reasonable_ compensation” are difficult of construction
and lead frequently to long litigation.
(3.) _Doors or Gates opening outwards._--
Section 71 of the Towns Improvement Clauses Act 1847 enacts that “All
doors, gates and bars put up after the passing of the special Act within
the limits thereof, and which open upon any street, shall be hung or
placed so as not to open outwards, except when in the case of public
buildings the commissioners allow such doors, gates or bars to be
otherwise hung or placed; and if (except as aforesaid) any such door,
gate or bar be hung or placed so as to open outwards on any street, the
occupier of such house, building, yard or land shall, within eight days
after notice from the commissioners to that effect, cause the same to be
altered so as not to open outwards; and in case he neglect so to do the
commissioners may make such alteration, and the expenses of such
alteration shall be paid to the commissioners by such occupier, and
shall be recoverable from him as damages, and he shall in addition be
liable to a penalty not exceeding 40_s._”
Section 72 of the same Act further enacts, “If any such door, gate or
bar was before the passing of the special Act hung so as to open
outwards upon any street, the commissioners may alter the same so that
no part thereof when open shall project over any public way.”
It is naturally necessary that doors or gates of all public buildings
should hang so as to open outwards, so as to give a free and easy exit
in case of panic, many serious accidents having arisen from a want of
this precaution; but with regard to private premises the case is
altogether different, and if doors and gates were allowed to open
outwards, they would soon become a dangerous and intolerable nuisance.
It will be seen that there are two courses to be pursued in connection
with this offence.
The first is where the door, gate or bar has been placed before the
passing of the Towns Improvement Clauses Act in 1847, in which case the
“commissioners may alter the same, so that no part thereof when open
shall project over any public way.” This duty of course rests with the
town surveyor, and in many cases it is not easy of execution, as
structural difficulties may have to be encountered and overcome.
In the second case, where the door, gate or bar has been placed since
the passing of the Act in 1847, certain penalties are incurred by the
occupier or owner, and the commissioners may also alter the door, gate
or bar at his expense.
The following specimen form of notice to be served in connection with a
case of this description may be of use:
____________ TOWN SURVEYOR’S OFFICE.
SIR,
I beg leave to give you notice that of the premises in your
occupation opens outwards, and when open, projects into the street
called or known as .
I have therefore to require that you will be good enough to have such
altered so that it shall not open outwards into the said
street, within eight days next after your receipt of this notice.
I beg leave also to give you notice that if you neglect to make the
alteration required within the period specified by this notice, you
render yourself liable to a penalty of 40_s._, and I shall proceed to
make the necessary alterations, and recover the costs and penalties
from you as the law directs.
I am, Sir, your obedient Servant,
______________________________
_Town Surveyor._

(4.) _Vault or Cellar Coverings._--
Section 73 of the Towns Improvement Clauses Act 1847 enacts, “When any
opening is made in any pavement or footpath within the limits of the
special Act, as an entrance into any vault or cellar, a door or covering
shall be made by the occupier[139] of such vault or cellar, of iron, or
such other materials, and in such manner as the commissioners direct,
and such door or covering shall from time to time be kept in good repair
by the occupier of such vault or cellar: and if such occupier do not
within a reasonable time make such door or covering, or if he make any
such door or covering contrary to the directions of the commissioners,
or if he do not keep the same when properly made in good repair, he
shall for every such offence be liable to a penalty not exceeding five
pounds.”
Besides the penalty, the person negligently leaving the covering in a
dangerous condition would be liable to an action for damages at the suit
of anyone who had sustained an injury in consequence of the covering
being so kept.[140]
There is another clause incorporated in the Public Health Act 1875 from
the Towns Police Clauses Act 1847 upon this subject, which is as
follows:
“Every person who leaves open any vault or cellar, or the entrance from
any street to any cellar or room underground, without a sufficient fence
or hand rail, or leaves defective the door, window or other covering of
any vault or cellar . . . . shall be liable to a penalty not exceeding
40_s._ for each offence, or in the discretion of the justice before whom
he is convicted may be committed to prison, there to remain for a period
not exceeding 14 days” (10 & 11 Vic. c. 89, s. 28).
But the former section I have quoted is that upon which the town
surveyor generally acts.
In connection with this duty the following is given as a specimen
notice:
SIR,
I beg to call your attention to the fact that the door or covering to
the vault or cellar in your occupation, No. Street, is
not in good repair (and is slippery and dangerous to
foot-passengers),[141] you are in consequence liable to a penalty of
5_l._
I must request you will be good enough to have such door or covering
properly repaired and made good in accordance with the construction
required by law, within days from the date hereof, and in the event of
your failing to do so, proceedings will be taken to enforce the
penalty to which you are liable without further notice.
I am, your obedient Servant,
______________________________
_Town Surveyor_.
To _______________
In accordance with the provisions contained in the section of the Towns
Improvement Clauses Act 1847 which I have quoted, that the “door or
covering shall be made by the occupier of such vault or cellar of iron
or such other materials, and in such manner as the commissioners
direct,” most towns in this country have prescribed the size and
materials of which they shall be made, the size being often limited to 6
feet in length, by 20 inches projection, from the line of plynth of the
building, for cellar coverings or pavement lights as they are sometimes
called, and 12 inches in diameter for coal plates.
Hayward’s patent hexagonal and semiprismatic pavement lights, however,
have obviated the danger of slipping upon this description of covering,
and consequently little or no inconvenience is experienced, even if the
greater portion of the foot pavement is covered by them.[142]
Coalhole plates should be so firmly fixed as to prevent the possibility
of their shifting, even when the rebate of the flag stone into which
they are dropped is worn, and also to prevent mischievous persons from
raising them.
Here let me state that no person can without the written consent of the
urban authority cause “any vault, arch or cellar to be newly built or
constructed under the carriageway of any street” (38 & 39 Vic. c. 55, s.
26); but from this section it does not appear illegal to construct a
vault, arch or cellar under the footpath, which would generally be the
extent to which such constructions would be extended. However, the more
general powers contained in section 149 of the same Act, by which all
“streets and the pavement stones and other materials thereof” vest in
and are under the control of the urban authority, give the necessary
powers to prevent the construction of cellars under any portion of the
foot-pavement without the consent of the urban authority.
The usual practice adopted is for any person who requires to construct a
cellar under the foot-pavement or carriageway of any street, to apply to
the urban authority for the necessary permission to do so. In granting
the permission, the urban authority call upon the owner of the premises
to which the proposed vault or cellar is attached, to enter into an
agreement acknowledging that the cellar or vault is only an easement,
and agreeing to remove the encroachment whenever called upon by the
urban authority to do so.
These agreements and any other similar easements should be kept together
in a book, which may be called the “Easement Book,” and indexed in such
a manner that a reference can be easily made at any time to any
easement that has been granted.
(5.) _Rain-water from Shutes or Down Pipes._--
Water may not be allowed to drip on to the pavements of the streets from
the adjoining houses, and the following clause from the Towns
Improvement Clauses Act 1847 has been incorporated with the Public
Health Act 1875:
