FIRES IN AMERICA.

The exceeding dryness of the atmosphere in the United States produces

such an inflammability in buildings, that when a fire breaks out it

proceeds with surprising velocity. Owing to this circumstance Americans

have organised the most perfect system in the world of extinguishing

fires, though all their efforts are often in vain. A stranger in New

York or Boston would be astonished at the immense uproar caused by an

outbreak of fire. Bells are rung, gongs sounded, and steam fire-engines

rush along the streets regardless of everything. The unaccustomed

stranger is apt to make a run of it when he sees the engines coming;

the American simply steps on to the ‘side-walk’ or into a ‘store’ for

a moment. It is provided by the city government that ‘the officers and

men, with their teams and apparatus, shall have the right of way while

going to a fire, through any street, lane, or alley,’ &c.; and most

unreservedly do the said officers and men make use of this permission.

If any old woman’s stall is at the corner of a street round which the

steamers must go, there is no help for it; over it goes. If a buggy

is left standing at a corner, the owner must not be surprised if but

three wheels are left on it when he returns. Accidents of this latter

kind, however, are rare; people recognise and yield willingly the right

of way; and the quicker the engines go to a fire, the better pleased

everybody is. It is quite a point of rivalry among the firemen who

shall get the first water on a fire, and is mentioned always in the

report of the engineer.

This is how it looks from the outside; but the greater part of those

who see the engines go to a fire have no idea of the inner working of

the system. All they know is that when there is a fire the engines

go and put it out. We shall therefore now proceed to shew, first,

the means for communicating alarms of fire; and second, the means for

extinguishing fires when discovered.

There are in Boston (Mass.), which we may take as an example of a

well-protected city, about two hundred and thirty-five alarm-boxes,

which are small iron boxes placed at street corners, on public

buildings, and in any convenient and necessary locality. Each box is

connected by two wires with the head office at the City Hall, and has

its number painted in red, and a notice stating where the key is kept,

which is generally the nearest house. The authorities usually confide

the key to some person whose premises are open all night, such as

the proprietor of an hotel, an apothecary, or a doctor. When the box

is opened, nothing is seen but a small hook at the top, the interior

being concealed by another iron lid. Under this second lid is a steel

cylinder with pieces of ebony let into its circumference to correspond

with the number of the box. This cylinder is connected with one of the

telegraph wires; and a steel spring which presses against it, with the

other. When the hook is pulled down a clock-work arrangement causes the

cylinder to revolve four times; the steel spring consequently passes

over the entire surface of the cylinder four times, and contact is

broken at the points where the spring touches only the non-conducting

ebony. For instance, if the circumference of the cylinder in box 125

could be unrolled, it would present an appearance something like

this: I II IIIII. Let us now follow the wires to the top of the City

Hall, where, night and day, sits an operator watching the recording

instrument. Here in a small room are numerous electrical instruments

of all sorts, gongs, switches, keys, levers, and wires. In an attic

overhead are the batteries. As soon as a box is opened and ‘pulled’ a

bell strikes, and a recording instrument in front turns out a slip of

paper, on which is printed the box number; thus

— — — — — — — —

would mean box 125. It prints this four times—the number of revolutions

made by the cylinder in the box—to avoid any error.

On the other side of the operator are three clock faces bearing

numerals from one to nine, and a pointer. The one to the right is for

the units, the middle one for the tens, the one to the left for the

hundreds. Under them is a lever working horizontally. Immediately the

operator receives the box number, he sets these pointers to correspond

with it—namely, the left one he puts at 1, the middle at 2, the right

one at 5—thus making 125—and then moves the lever underneath.

Now let us see what is the result of this manœuvring. Wires connect

these machines with various church bells and gongs in all parts of

the city, which ring out the alarm as the operator moves the lever.

There are thirty-eight such bells in Boston. When there is a church

bell in the neighbourhood, the fire department affixes an electrical

hammer to it; if, however, there is no public bell in the right place,

a large gong is erected. The machine at City Hall is automatic when

once started, and causes the bells to sound the alarm three times as

follows. For box 125 they would strike once; then a pause and strike

twice; another pause and strike five times; then a much longer pause

and repeat twice. For box 218 they strike 2—1—8, always sounding the

number three times with intervals between. So quickly is all this

managed that in half a minute after a person opens and ‘pulls’ a box he

hears the bells begin to respond.

In case that the engines which go on the first alarm are not

sufficiently numerous to extinguish the fire, a second alarm is given

by the operator striking ten blows on the bells, which brings several

more engines. If the fire is very serious, a third alarm brings still

more engines with hose and ladder companies. This is given by striking

twelve blows twice. If the conflagration is becoming very serious

indeed, the entire fire department is summoned by striking twelve blows

three times. This, of course, very rarely happens. Indeed so efficient

are the men and apparatus, that even a second alarm is quite unusual.

The second and third alarms are communicated to the City Hall operator

by simply ‘pulling’ the same box a second and third time; or if the

pulling apparatus should have been destroyed at an early stage of the

fire, by transmitting a request by a Morse telegraph key, which is

placed in every box for the use of the employés when out testing the

circuits. Every one knows the number of the box situated near to his

residence or place of business; so, if awakened by the bells in the

night, he simply counts the box number, and if it is not near him,

turns over and goes to sleep again reassured; whilst if it chance to be

his number, he is at once ready to render any assistance.

The fire telegraph is also made use of by the city authorities for

calling out the police or the military in case of a disturbance, and

also for informing the parents who send their children to the public

schools when there is to be no class, on account of bad weather or

other reasons. Each of these circumstances has its special number.

There is also a gong placed in every police station, which is struck

directly from the boxes, and it frequently happens that the police have

a flaming building barricaded by a rope, before the engines arrive.

Next, the means for extinguishing fires when discovered. In the city

of Boston there are twenty-nine steam fire-engines in actual service,

and seven held in reserve; eight chemical engines, throwing water

impregnated with soda and sulphuric acid, which also serves as the

motive-power; one steam self-propelling engine; one fire-boat to defend

the water-front of the city; nearly forty hose carriages, about seventy

thousand feet of hose, and twelve hook and ladder companies; besides

other apparatus of various kinds, such as hand-engines, coal-wagons,

sleighs for carrying the hose in winter, and several aërial ladders.

The engines weigh from seven to nine thousand pounds, and cost about a

thousand pounds each.

One of the most interesting features in the American fire-system is

the extreme ingenuity that is exercised to insure the speedy arrival

of the apparatus at a fire. As has been said, in less than a minute

after the alarm-box has been pulled the bells are ringing out the alarm

all over the city; and—incredible as it may seem—sometimes in _ten

seconds_ after the alarm is rung, the engines have left their stations

with steam up and every one prepared for work! Perhaps the best way to

give a general idea of how this wonderful celerity is attained is to

describe the interior arrangements of an engine-house.

Usually an engine and a hose-carriage are kept in one house. This is

a two-story building with a small tower or look-out. In the cellar

are kept the steam-heaters and coal; on the first floor in front are

the engine and hose-carriage, at the back the stables; on the second

floor the sleeping-room of the men, their smoking and reading room,

and a small tool-shop. There is a sort of wooden tunnel running up by

the side of the stairs from the cellar to the top of the house, in

which are hung the lengths of spare hose. In the front of the building

is a large gateway, kept closed, for the entrance and exit of the

engine. The engine stands facing the door, and by the side of it the

hose-carriage. The firemen’s helmets and coats are hung on these; and

in the engine the materials for getting up the fire are laid at the

bottom; and close by is a sort of tow-torch soaked in oil, which is

lighted and thrown on the fire by the engineman when they start. So

inflammable is the material laid in the engine-furnace that the fire is

lighted instantaneously. Coming up through the floor, and connecting

with two pipes at the rear of the engine, are two tubes from the

steam-heater mentioned above. This is simply a small boiler by which

the boiler of the fire-engine is kept filled night and day with hot

water, so that steam is up immediately after the fire is lighted. By

the side of the engine is a large gong, on which the alarm is sounded

by the same current that causes the strokes on the bells outside. Under

this is a lever holding back a powerful spring, which, when released,

opens the stable-doors without any attention from the firemen!

There are three horses—two for the engine, and one for the

hose-carriage. They are kept in small stalls, and face the door of the

house, with the door of the stall just in front of them, so that when

the door is opened, the horses, on stepping out, stand by the side of

the engine in readiness to be harnessed. And not only this, but the

horses, without exception, are so well trained, that the instant the

door is opened they run out and stand by the side of the engine-pole.

They are always completely harnessed, and their harness is so

constructed that in order to attach them to the engine only the joining

of a few snap-hooks is necessary.

One fireman is always on patrol on the ‘floor,’ whose duty it

is to count and register the alarm; another is on patrol in the

neighbourhood. They sleep with everything on but their coat and boots,

and each has a distinct place assigned to him, which he takes on the

striking of an alarm. So the gong strikes, the stable-doors open, the

horses rush out, the men tumble down-stairs from their rooms above, the

horses are harnessed; and if the alarm calls for them, the doors are

thrown open, and they are gone, occasionally, as was said, in ten or

twelve seconds from the striking of the alarm.

The city of Boston is divided into ten fire districts, and each

district placed under the charge of an assistant-engineer. Usually

about five or six engines, with their accompanying hose-carriages, two

hook and ladder companies, a coal-wagon, and one of the wagons of the

protective brigade—carrying tarpaulins and rubber blankets, to protect

property from injury by water, supported by the insurance companies—go

to every fire. The entire force of the Fire department in 1876 was six

hundred and sixty-seven men, controlled by three fire commissioners,

one nominated by the mayor, and confirmed by the city council every

year.

Such are the means possessed by a city of rather more than four hundred

thousand inhabitants for protection against fire; and with such a

splendid system and such a force of men and machines, it is difficult

to understand how a fire could attain such awful proportions as that of

1872, when the loss amounted to four millions sterling.

Boston always took great pride and felt much confidence in her

granite-fronted places of business, but her recent fire has relieved

her of that misplaced confidence. The blocks of granite crumbled away,

cracked and fell apart, and even exploded. Of course this was an

exceptionally great heat, but one sees fewer warehouses fronted with

granite now than before the fire.

Even during so terrible a calamity as this fire the characteristic

wit of the American did not desert him. No sooner were the flames

extinguished in the burnt district, than the occupiers of the premises

put up notices on their lots stating their present residences and

future plans. Usually, in the larger cities of the United States, a

value is put upon time of which we have no conception in England. When

a house is burnt down in London or Edinburgh, half a year may elapse

before arrangements are made to build it up again. On the morning

after a fire in New York, we were amused in observing that workmen

were already engaged in preparations for a new building. Owing to

this species of energy in the American people, the two half-destroyed

cities of Boston and Chicago are built up again, handsomer and stronger

than ever. And still the work of improving the fire department goes

on. There are in the newspapers almost daily accounts of the trial

of new engines, improved ladders, longer fire-escapes, and surer

fire-extinguishing compounds, and nothing is spared in checking the

tyranny of what has been so aptly termed a ‘good servant but bad

master.’
