CHAPTER II.

ENGLISH RIVERS.

“Rivers, arise; whether thou be the son

Of utmost Tweed, or Ouse, or gulphy Don,

Or Trent, who, like some earth-born giant, spreads

His thirty arms along the indented meads;

Or sullen Mole, that runneth underneath;

Or Severn swift, guilty of maiden’s death;

Or rocky Avon, or of sedgy Lee;

Or coaly Tine, or ancient hallowed Dee;

Or Humber loud, that keeps the Cythian’s name;

Or Medway smooth, or royal-towered Thame.”

—_Milton._

One of the earliest pioneers of inland navigation was Wm. Sandys,

of Ombersley Court, in Worcestershire, who, in 1636, applied for

Parliamentary powers to make the river Avon navigable for boats and

barges, from the Severn at Tewkesbury to the city of Coventry. Part

of the work which was executed in pursuance of the powers so obtained

exists to the present time. In 1661 Sandys sought for Parliamentary

authority to make the Salwarp navigable from the Severn to his own town

of Droitwich, and to make navigable the rivers Wye and Lug, and the

brooks running into the same in the counties of Hereford, Gloucester,

and Monmouth.

Our great rivers, the Thames, Severn, Trent, Ouse, &c., were the

recognised means of transit long before the time of the Romans, who

were so far advanced in inland navigation as to cut canals of forty

miles in length, as instanced in the Caerdyke, between Peterborough and

Lincoln (though now filled up), as also to build docks, as shown in the

old dock walls, &c., still standing at the outfall of the Trym into the

Avon below Bristol.

The Fossdyke navigation from Lincoln to the Trent is also of Roman

origin, and probably an extension of the Caerdyke, on their route to

York. Torksey, at the junction with the Trent, was a Roman town and

fort, and continued possessed of many privileges, down to the Norman

period, on condition that the knights who held it should carry the

King’s Ambassadors, as often as they came that way, down the Trent

in their own barges, and conduct them to York. This is recorded in

‘Domesday Book.’ Itchin Dyke to Winchester was also cut by the Romans.

It is usual to date the first beginning of canal navigation in England

from the time when Brindley constructed the famous canal between

Worsley and Salford for the Duke of Bridgwater. This, no doubt, was

the first important artificial navigation throughout. But Sandys had

practically undertaken canal construction about a hundred years before.

The Act of Parliament which sanctioned the various enterprises that he

had projected, authorised him to construct new channels, and to set

up, in convenient places, “locks, wears, turnpikes, penns for water,

cranes, and wharfs, to lay timber, coals, and all other materials that

shall be brought down;” to have and use “a certain path, not exceeding

four feet in breadth, on either side of the said rivers and passages,”

for the “towing, pulling, or drawing-up of their barges, boots,

leighters, and other vessels passing and repassing them, or any part

of them, by strength of men, horses, lines, ropes, winches, engines,

or other means convenient;” and “to dig, carry, trench, or cut, or

make any trench, river, or new channel, or wharf,” &c., after having

arranged with the “respective Lords, owners, or occupiers of the said

lands.”[29]

Sandys, however, did not succeed in carrying out the intended

navigation between the cities of Hereford and Bristol as he proposed.

He attempted to make the Wye navigable by locks and weirs on the

pound-lock system, which did not suit its rapid current. The enterprise

was accordingly abandoned, after a trial of several years.

In 1688 the project of making the Wye navigable was revived. It was

now proposed to abandon the pound-lock system, to purchase and remove

all the mill-weirs and fishing-weirs between Hay, in Herefordshire,

and the sea, and to deepen the channels of the shallow streams. The

weir-owners rose in opposition to these proposals, and for several

years the subject was the occasion of a bitter controversy. When the

Bill was applied for in 1695, the city of Hereford, and thirty-two

parishes in the county, petitioned in its favour; while the towns of

Ross and Monmouth, and thirteen parishes, petitioned against it. The

Bill, however, ultimately became law,[30] and although, owing to the

uncertainty of its depth and current, the Wye was never adapted for

regular navigation, it was so far improved that throughout the

eighteenth century it was of great service to the county of Hereford.[31]

One of the earliest to advocate river improvements in Britain was

Andrew Yarranton, an original genius, who had ideas and plans quite

a hundred years in advance of his times.[32] He occupied himself with

many different projects designed to effect improvements in means

of communication, and in developing the resources of the country

generally. At one time serving as a soldier, at another engaged in the

manufacture of iron; now planning how to provide employment for the

poor, and again studying how to bring about more economical processes

of husbandry, Yarranton made a special hobby of the improvement of

navigation, undertaking surveys of the principal rivers in the West of

England at his own cost, and urging upon the people the importance of

opening up the facilities of communication thereby available to them.

In 1665 Yarranton proposed to the burgesses of Droitwich to deepen

the small river Salwarp, so as to connect that town, now an important

centre of the salt industry, with the river Severn. He was offered

terms to carry out his plans, but the offer does not appear to have

been good enough.[33]

In 1666 Yarranton proposed to make the river Stour navigable between

Stourport and Kidderminster, and to connect it with the river Trent by

a navigable canal. He carried out this work so far as to make the river

navigable from Stourbridge to Kidderminster; but his scheme was not

completely adopted for lack of means. He says that he “laid out near

1000_l._,” and “carried down many hundred tons of coal,”[34] although,

on account of the novelty of his enterprise, it was greatly ridiculed.

At a later date Yarranton proposed to connect the Thames and the

Severn by means of an artificial cut, “at the very place where, more

than a century after his death, it was actually carried out by modern

engineers.”[35]

Although the proprietors in what was called the “Old Quay Company”

had obtained an Act of Parliament in 1733 for improving by weirs and

cuts the rivers Mersey and Irwell, between Runcorn and Manchester, the

first association incorporated for making a regular navigable canal in

England was not till more than twenty years later, six centuries after

the first canals in Italy and Flanders, and a hundred years subsequent

to some of the chief canals of France being in operation. It is but

fair to add that England carried the movement further than most other

countries.

It is unnecessary to enter into the history of the development of the

navigable resources of the rivers of the United Kingdom during the last

two centuries, even if it were possible, which, of course, it is not

in a work of this description. The dates when the several principal

navigation works were undertaken will be found set out in Appendix I.

But we may, nevertheless, bestow some consideration upon the principal

steps that have brought about the remarkable facilities that England,

Scotland, and, to a less extent, Ireland, respectively enjoy at the

present time in the matter of internal transport. The Clyde, the

Tyne, the Tees, the Wear, and other prominent English rivers have

been transformed from shallow brawling streams, some of them easily

fordable at all states of the tide, into magnificent waterways, capable

of bearing on their bosoms the largest vessels afloat. This work has

necessarily involved great engineering capacity, a large expenditure,

and a judicious administration of their powers and resources by the

public bodies through whom it has been carried to completion.

THE MERSEY.

On the Liverpool side of the Mersey there are sixty docks and

basins of the ordinary type, having a total water area of 368 acres

and 25 miles of quay berthing. On the Birkenhead side, there are

164½ acres of docks, with 9½ miles of quayage, three graving docks,

having a total length of 2430 feet, and every facility for loading and

unloading ships.

The total expenditure incurred on this enormous provision for shipping

has been upwards of twenty millions, and the total annual revenue of

the Mersey dock estate is about a million and a half sterling.

The entire length of the Mersey is 56 miles. For the first 37 miles

of this distance, the river has a tortuous course, ill-adapted for

navigation, and passes through an almost exclusively agricultural

country. From Runcorn to the sea, the form of the river is that of a

bottle, of which the wide expanse between Runcorn and Liverpool forms

the body, and the narrow part opposite Liverpool the neck. Through this

neck there annually passes nearly twenty million tons of shipping,

including entrances and clearances.

The unassisted efforts of nature have hitherto maintained the navigable

channels of the Mersey, so that the conditions of navigation remain

practically uniform. The bar, however, is gradually moving in a seaward

direction, while maintaining its general form and characteristics. In

Liverpool Bay there is a great range of tide, which insures a depth

of at least 30 feet over the bar once in every twelve hours, even on

the lowest neaps. Some two or three million cubic yards of upland

water every twelve hours are discharged into the estuary, chiefly by

the Mersey and the Weaver, which, with 710 million cubic yards on a

high spring tide, maintains the normal capacity of the estuary, and

counteracts the process of silting. Some 17,300 acres of a deposit of

sand in the estuary are above the low-water mark. Through this the

upland water forms and maintains a channel in its course to the sea,

and any serious exclusion of this tidal water would be likely to so far

injure the sea channels as to interfere with the trade and shipping of

the port.

The Mersey is the outlet for several important canal navigations,

including the Weaver Navigation Canal, near Weston Point, the

Bridgwater Canal at Runcorn, the Sankey Canal at Widnes, the Shropshire

Union Canal at Ellesmere, the Leeds and Liverpool Canal at the Docks,

and the Manchester Ship Canal, now under construction, at Eastham. The

position of these several canals in relation to the river may be traced

in a map accompanying a paper read by Mr. Lyster, the engineer, before

the Institution of Naval Architects. These canals are important factors

in assisting the growth of the trade of the Mersey. The Leeds and

Liverpool is, however, the only canal that has a direct connection with

the Liverpool Docks.

By this canal Liverpool has water communication with the important town

of Leeds, and thence, by the Aire and Calder Canal, with Hull and the

other ports on the Humber. By the Shropshire Union Canals the Mersey is

connected with the network of canals in the Midland Counties and with

the River Severn.

In Camden’s time Liverpool must have been a very obscure place. The

author of ‘Britannia’ dismisses it almost in a sentence, observing that

“from Warrington, the River Mersey, spreading abroad, and straightwaies

drawing in himselfe again, with a wide and open outlet, very commodious

for merchandise, entereth into the Irish Sea, where Litherpoole, called

in the elder ages Lipen-poole, common Lirpoole, is seated, so named, as

it is thought, of the water spreading itself in manner of a poole.”

With the exception of the Thames—which it rivals, and with which for

a number of years past it has run a neck-to-neck race—the Mersey is,

so far as its volume of business is concerned, the most important river

in the world. This, however, is an attainment of comparative modern

origin. The first wet dock was constructed at Liverpool, in 1708-9,

on the site now occupied by the Custom House. In the latter part of

the same century several other docks were constructed. The dock estate

has now an area of 1078 acres, the whole of which is appropriated to

basins, docks, quays, and premises worked in connection therewith.

THE WEAVER.

The history of the navigation of the river Weaver, which adjoins the

Mersey in Cheshire, supplies a notable example of what may be made of

an originally insignificant and tortuous stream in order to adapt it

for the requirements of commerce. The river has been canalised between

Northwich and Chester, twenty miles of the navigation being artificial

navigation, and the other thirty miles being river proper.

In 1721 three Cheshire gentlemen obtained the first Act of Parliament

for making the river Weaver navigable. The depth then provided for was

only 4 feet 6 inches, and boats of more than 40 to 50 tons could not

enter.

About the year 1760, the navigation was carried down so as to enable

vessels to enter at nearly all tides, and in 1810 the river was further

improved by the Weston Canal, which is four miles long, enabling

vessels of much deeper draught to enter without navigating a dangerous

part of the old river. This canal forms a junction with the Bridgwater

Docks at Weston Point, and a dock was formed in connection with it so

as to enable vessels to wait for the tide.

In 1830 the depth was increased to 7 feet 6 inches, with locks 88 feet

long and 18 feet wide, capable of taking cargoes of 100 to 150 tons.

There were at this time eleven single locks on the river, not including

the entrances to the Mersey. About 1860, a second set of locks, having

10 feet of water on the sills, and 100 feet long by 22 feet wide, was

placed by the side of the existing locks, and the number was reduced to

nine pairs. The larger size, owing to the vessels being built almost to

the shape of the lock, were capable of passing vessels with nearly 320

tons on board.

This continued until about seventeen years ago, when it was decided to

replace these locks by some of very much larger dimensions, and also to

greatly reduce the number. With this object, locks were built at Dutton

and Saltersford near the site of existing locks, and of sufficient

height of walls to enable the two ponds above to be thrown into one,

thus doing away with the four smaller locks. The same has been done at

Hunts, and, more recently, at Valeroyal, above Northwich. The locks at

Dutton and Saltersford are entirely built of masonry, having limestone

sills and rubbling courses, with the intermediate part sandstone. All

the work on the river is of this description, with the exception of the

Hunts and Valeroyal large locks, which are built of concrete.

When these improvements are completed there will be only four locks on

the twenty miles of navigation, the larger of each pair of locks being

220 feet long, by 42 feet 6 inches wide, and having 15 feet of water

on the sills. Most of the river is now dredged to 12 feet, there only

being 10-feet bars at certain points. The ordinary width is about 95 to

100 feet at water level, and 45 feet at the bottom. More than a million

tons of salt annually pass down the Weaver to the Mersey.

THE TYNE.

This noble river, from Newcastle to the sea, is one of the greatest

triumphs of modern engineering. Good old Camden quaintly remarks, that

“where the wall (Roman) and the Tine almost met together Newcastle

sheweth itself gloriously, the very eye of all the townes in these

parts, ennobled by a notable haven, which Tine maketh, being of that

depth that it beareth very tall ships, and also defendeth them, that

they can neither easily be tossed with tempests nor driven upon

shallows and shelves.”[36]

No better example of what has been done within recent years in the way

of providing additional facilities for the wants of British shipping,

could be quoted than the case of the Tyne. That river is the natural

outlet of the great northern coalfield. It is also the outlet for a

very great trade in chemicals, engineering, iron and steel, and other

industrial products. But in order to adapt it for the purposes of

its large and rapidly-growing commerce, it was necessary not only to

provide several docks—the more important of which, the Northumberland

and the Coble Dene, cost 352,000_l._ and 528,000_l._ respectively—but

it was also requisite to expend over 1,300,000_l._ in dredging the bed

of the river, so as to provide access for the largest size of vessels,

to expend nearly three-quarters of a million on other river works,

to construct North and South Piers at a cost of over 820,000_l._;

and to incur a total outlay considerably exceeding 4,000,000_l._ The

effect of these improvements and structural works has been that the

Tyne has been transformed from “a series of shoals, with a narrow and

generally serpentine channel between and past them, through which

vessels of about 15-ft. draught could get up at high-water spring

tides, whilst at low-water it was a not uncommon occurrence for small

river steamers, drawing from 3 to 4 ft. of water, to be aground on

their passage between Shields and Newcastle for three or four hours,”

to a magnificent navigable highway, that admits vessels of 3000 tons

and upwards at all states of the tide with perfect safety. At the time

that the great work was commenced, and for many years afterwards,

the revenue from shipping dues was quite insufficient to enable any

substantial progress to be made, and the trade grew so rapidly that

it became imperative to either borrow money in order to carry out the

required works, or allow the shipping to seek other ports, where better

facilities were provided. The works to the end of 1882 had, therefore,

to be chiefly carried out by the aid of borrowed money. As a matter of

fact, only 426,000_l._ was expended out of income, while 3,673,000_l._

was borrowed. The results, however, appear to have justified the

course. The annual income from dues and tolls has grown, within twenty

years, from 91,000_l._ to over 251,000_l._

The Tyne Improvement Commission, chiefly under the presidency of Sir

Joseph Cowen, have deepened the river to a uniform depth of nearly 30

feet, built training walls, dredged the bar, built new channels, and

otherwise revolutionised the old order of things. The results have been

extremely striking. In 1888 14,668 vessels, having a total tonnage of

6,734,000 tons, cleared from the Tyne ports; while 6093 ships, having

1,662,000 tons register, entered the same ports. The people of Tyneside

are proud of their river, as well they may be.

THE RIBBLE.

Preston is a busy town and port in the county of Lancashire, situated

on the river Ribble, about seventeen miles from the sea. The navigation

of the port has hitherto been confined to coasting vessels drawing

about 14 feet of water. The amount of shipping entering the port has

been under 30,000 tons a year. The Ribble rises in the West Riding of

Yorkshire, at the east foot of Whernside, and arrives at Preston after

a course of fifty-seven miles. With its tributaries it drains about 800

square miles of land, a great part of which is moorland. The annual

rainfall over this district averages about 37 inches. Below Preston,

the channel of the river opens out into a broad sandy estuary, four or

five miles in width, the whole of which is covered at high water of

spring tides, and the greater part of which is dry at low water. The

course of the river, after it leaves the trained portion, is along the

northern shore of this estuary to Lytham, whence the main navigable

channel, called “The Gut,” bends in a south-westerly direction between

the Salt-house and the Horse-shoe banks to the Irish Sea. The width of

the estuary between the two forelands on the coast, Stanner Point on

the north, and Southport on the south, is five miles. The sands extend

four miles seaward beyond this line, and are uncovered at low water.

The depth at low water spring tides on the bar, or the portion of the

navigable channel with deep water, is four feet. Beyond this the depth

seawards rapidly increases, from 20 feet immediately beyond, till,

at the Nelson buoy—which is two miles beyond the bar, and the first

buoy belonging to the Ribble navigation—the depth is six fathoms. The

depth above the bar along the Gut channel, which is rather tortuous

and narrow, being shown on the Admiralty chart as less than a quarter

of a mile wide, varies from 4 to 24 feet. This channel is buoyed out

with eight buoys, which are shifted as the channel varies. There are

three other channels between Lytham and the sea, called, respectively,

the South Channel, the Penfold, and the North Channel. These are more

or less navigable; but the Gut is the main sea-fairway. From Lytham a

shallow channel runs near the shore for about a mile to “The Dock,”

where ships can lie at anchor. Thence it winds towards the Wage through

the sands. This channel is continually shifting its course, owing to

gales and freshets. From this point the river has been trained by

rubble-stone training walls, put in about thirty-four years ago, which

continue for seven miles up to Preston. These walls rise seven feet

above low water, and are 300 feet apart at the top. Spring-tides rise

24 feet at the bar, and neaps 17 feet, and at Preston the rise is 10

feet and 4 feet 6 inches. The project of constructing a dock at Preston

has been agitated for some years, and has been strongly advocated

by Mr. Garlick, M.I.C.E., who was the engineer to the Navigation

Commissioners. It was considered that by providing deep-water

accommodation to the town, its trade and prospects would be greatly

increased, having regard to the large manufactories by which it is

surrounded, the immense population in the immediate neighbourhood, and

the nearness of the Wigan coalfield. This work is now in progress,

including the division of the river; the estimated cost being about

440,000_l._

THE SEVERN.

This famous river is navigable up to Welshpool, a distance of 155 miles

by water, from the mouth of the Bath Avon river. The extreme branch

of this river may be traced for about 45 miles above Welshpool, to

Plinlimmon Hill, and numerous other branches extend for great distances

into the country on both sides. The whole of this great length of

navigation was, till lately, unimproved by art, the river having no

locks, weirs, or other erections throughout its whole length, for

surmounting the numerous shallows and irregularities which the current

over variable strata had formed in its bed. The first or lowest 42

miles of this river, extending to the city of Gloucester, are very wide

for a great part of the way, and have a most rapid tide; but the last

28 miles are so crooked, that ships are said to be often several days

in passing it; on which account, a ship canal, calculated for vessels

of 300 tons burthen, was in the year 1793 projected and begun between

Gloucester and Berkeley, of 18¼ miles in length, for avoiding these 28

miles of the river. From Gloucester to Worcester the distance is 30

miles by the course of the stream, the rise in this length being 10

feet, or at the rate of 4 inches a mile; from Worcester to Stourport

the distance by water is 13 miles, and the rise 23 feet, or at the rate

of 1 foot 9 inches per mile; from Stourport to Bridgnorth it is 18

miles, and the rise 41¾ feet, or 2 feet 4 inches per mile on the

average; and from Bridgnorth to the new town at the junction of the

Shropshire canal, called Coalport, the distance is about 7 miles, and

the rise about 19 feet, being a rate of about 2 feet 8 inches per mile.

William Reynolds, the founder of Coalport, caused an account to be

daily registered of the depth of the stream in the bed of the Severn at

that place, between the 7th of October, 1789, and the 23rd of December,

1800, of which Mr. Telford has given the particulars, except on twelve

occasions when the river had overflown its bounds and covered the usual

marks (on Sundays during some part of the time), the intervals of frost

in which the river was frozen over, and for three short intervals,

when, unfortunately, the experiment was by some accident suspended.

During all the months of January, in the above period of eleven years,

ending the 6th of October, 1800, the river does not appear to have

exceeded the depth of 16 feet, that being the greatest depth at any

time recorded; and several times, when no depths are inserted to the

great floods, it is stated in the table that the water was above all

the marks. Besides these, there were thirty-two smaller floods, or

times when the water had risen, and was falling again for some days

after; the highest of these had a depth of 13 feet (5th January, 1790),

the lowest 4 feet, and the mean of the whole of these floods is 7½

feet. In the months of February there were two of these overflowings,

one of which (11th February, 1795) followed a frost and continued for

five successive days: nineteen floods, the two highest of which were

equal (17th and 20th February, 1799) to 12 feet.

THE WITHAM.

On the Witham, for a distance of thirty miles, between Boston and

Lincoln, the river is practically a canal. The tide is stopped by

a sluice at Boston, and a weir and locks had to be constructed at

Bardney and Lincoln. The inland water is held up to a constant height

on the sill of this sluice by penstocks, for the purposes of the

navigation. The navigation having been taken over by the Great Northern

Railway Company, the works are maintained in efficient condition; but

the obligation imposed by the original Act of holding up the water

seriously affects the drainage. The river Slea, from Sleaford to the

Witham, was made into a canal in 1792. The navigation on this river

having almost entirely ceased, the company was dissolved by an Act of

Parliament. The Bane, another affluent of the Witham, was also

canalised, forming a navigation from the Witham to the town of

Horncastle; but the dues obtained are insufficient to maintain the

works in proper order.

THE NENE AND OUSE.

On the Nene, which is canalised from Peterborough to Northampton, the

navigation is reduced to a few barges. The constant floods on this

river are ascribed in a great measure to the defective condition of the

works. The proprietors of the navigation, on whom was cast the duty of

maintaining the river, no longer have the funds, and there is nobody

to take their place. The same thing has occurred on the Ouse between

Earith and Bedford.

On some of the affluents of these rivers, which, under legislative

powers granted last century, had been converted into “navigations,” the

proprietors have obtained Acts of Parliament relieving them of their

rights and liabilities, and there is now no jurisdiction over these

rivers, or anybody responsible for removing shoals or cutting weeds.

The beds of these streams have consequently become shallow, and they

are no longer capable of acting as efficient arterial drains. Thus,

on the Ivel, an affluent of the Ouse, the navigation trust, created

in the reign of George II., was abolished in 1876. The river is said

to have since diminished one-half in width, and one-half in depth,

and the bottom is being gradually raised to the level of the land. In

like manner, the Lark, another canalised affluent, has almost entirely

silted up since the navigation of the river ceased. The Ouse itself,

above Earith, is obstructed by numerous shoals, and an enormous growth

of weeds. These were originally kept down by the constant passage

of the vessels, and the shoals were removed by the trustees of the

navigation.

THE TEES.

The improvements that have been carried out for the purpose of opening

up the navigation of the river Tees, although less considerable than

those carried out for some of the larger rivers of Great Britain, are

yet entitled to take rank as among the most notable river engineering

achievements of the century. They are also among the most recent. It

was not until 1852 that the Act was passed creating the Tees Navigation

Commission. At that time there were three or four channels in the

estuary, all of them very shallow. The shifting sandbanks caused great

trouble and not a little danger to navigation, and the depth of water

near to Middlesbro’ did not admit of the passage of vessels of large

size. Since then, about twenty miles of low water training walls have

been erected for the purpose of confining the navigable channel. The

volume of water and its scour have thereby been much increased. The

river has been continuously dredged in order to secure a depth of

water that would allow of the passage of vessels of large tonnage into

the Middlesbro’ Docks. About 23 million tons of material have been

dredged from the bed of the river, and the channel has been generally

straightened and widened. Breakwaters have been constructed on both

sides, one of them, called the North Gare, being about two miles and a

half long. A remarkable feature of the work is that these breakwaters

have been constructed of slag, obtained from the blast-furnaces in the

neighbourhood. Some millions of tons of slag have been employed in this

way, the ironmasters having paid to the Conservancy Commissioners a

small sum for removing the slag, the disposal of which had been a great

source of difficulty previous to this application.

As a result of the works that have been carried out for the improvement

of the navigation of the Tees, the shipping trade of the river, and

especially of the port of Middlesbro’, has greatly increased. The main

element in this development has been the growth of the iron industry;

but the second element has undoubtedly been the increased facilities

for navigation. The popular impression about Middlesbro’ is that only

a single house stood in 1830, where there is now a busy town of more

than 70,000 inhabitants. This may or may not be a legend, but there is

no doubt about the fact that in 1850 there were only from two to three

feet of depth on the bar of the Tees, where it was possible to wade

across at low water; whereas now there is about 20 feet of water, and a

harbour of refuge has been provided in which ships can ride in safety

whatever the condition of the usually stormy seas outside.

THE IRWELL.

This river has been partly canalised, in order to afford a means

of communication between Warrington, Manchester, and other large

towns, and Liverpool, but it was only adapted for light craft and

has consequently fallen largely into disuse. The Mersey and Irwell

Navigation was acquired by the Bridgwater Company, and has now, with

the rest of the Bridgwater property, passed under the control of the

Manchester Ship Canal Company.

THE WEAR.

This river, which has its rise in the district that unites Durham and

Westmoreland, falls into the North Sea at Sunderland after a course

of thirty miles. The river is under the jurisdiction of the Wear

Commissioners from about nine miles from the bar to the sea. Over this

distance very considerable improvements have been carried out during

the last half century. These improvements have resulted in making the

Wear one of the foremost shipbuilding rivers in the United Kingdom, and

have given it the second place in the coal-shipping trade. The revenue

of the Wear Trust, which only averaged about 14,000_l._ a year between

1840 and 1850, has within recent years amounted to about 130,000_l._ a

year. One of the most extensive works undertaken on the river, besides

graving docks, wharves, &c., and the deepening of the bed, was the

construction of a lock at the sea outlet, designed to obviate the

detention of screw-colliers when waiting for the tide. This lock is 481

feet in length by 90 feet in breadth, and has a depth of 29½ feet at

ordinary spring tides. The present docks can accommodate 200 ships of

large size, drawing up to 24 feet of water. The area of the docks is

over 78 acres, and they are fitted with nineteen coal spouts, at which

15,000 tons of coal can be shipped daily.

In this chapter we have dealt with a few only of the more notable

examples of river improvement in modern times. The list might be almost

indefinitely extended. There is hardly a brawling mountain torrent

between Land’s End and John o’ Groat’s that has not been reclaimed,

deepened, widened, or otherwise improved upon by the art and the genius

of the engineer. Nor has the work been confined to modern times. The

Romans are known to have constructed embankments for the control of

British rivers during the period of their occupation, although for

something like 1000 years afterwards their example was not followed.

The engineers and the local authorities of the nineteenth century have

done much to redeem this reproach. The improvement and conservancy of

rivers have now been reduced to a science, founded mainly upon the

following general principles[37]:—

1. That the freer the admission of the tidal water, the

better is the river adapted for all purposes, whether of

navigation, drainage, or fisheries.

2. That its sectional area and inclination should be made to

suit the required carrying power of the river throughout its

entire length, both for the ordinary flow of the water and

for floods.

3. That the downward flow of the upland water should be

equalised as much as possible throughout the entire year; and

4. That all abnormal contaminations should be removed from

the streams.

Our tidal rivers are undoubtedly one of the chief sources of our

maritime supremacy. For this reason it is of the utmost importance

that they should be kept in good repair, free from unnecessary

obstructions, and well adapted to the purposes of navigation. As it is,

however, this is not always the case. The chief reason for existing

maladministration, where it exists, is the absence of a uniform system

of control. The Thames, for example, has been hitherto controlled

partly by the Thames Conservancy and partly by the Metropolitan Board

of Works. The Great Sluice, at Boston, in Lincolnshire, was constructed

in 1764 by Smeaton, for the purpose of stopping the flow of the tide

in the river Witham, and converting the upper part of the river into a

fresh-water canal as far as Lincoln. As, however, the control of the

river is divided—one body dealing with the tidal part from the Grand

Sluice to the sea, and the other with the canal and drainage of the

land above—each opposes the schemes of the other, and the navigation

has been ruined.[38]

There is one course whereby this condition of things, where it

exists, may be prevented. It has been suggested that a new Government

Department should be created, with entire charge of and control over

all estuaries and navigable channels, and presided over by a member of

the Cabinet. The interests at stake are sufficiently large to justify

this.[39] They are as vital to our commerce and industry as any matter

now dealt with by the State, affecting our material well-being, and

they are every year increasing in extent and importance. As regards

the principal rivers—the Mersey, the Tyne, the Tees, the Clyde,

and the Wear especially—they are now controlled in accordance with

the recommendation made by the Duke of Richmond’s Select Committee,

that “each catchment area should be placed under a single body of

conservators, who should be responsible for maintaining the river, from

its source to its outfall, in an efficient state.” There are other

rivers, however, that are administered rather in the interest of the

landed proprietors than in that of navigation, and where these two come

into conflict the State should have powers that would enable the public

interest, which is both national and international, to be effectually

protected.

Many of the above rivers are not navigable for vessels of any size,

and are therefore not of much value to the transportation resources

of the country. In the majority of cases, also, the character of the

waterways, as regards locality, water-supply, &c., would not justify

any large expenditure in adapting them for purposes of transport.

[32] Andrew Yarranton was born in the parish of Astley,

Worcestershire, in the year 1616. He wrote a work which is well known

to economists, entitled ‘England’s Improvement by Land and Sea, or

How to beat the Dutch without Fighting,’ describing observations

that he had made during his travels in Holland, Saxony, and other

countries.

[33] Smiles states that Yarranton was offered 250_l._ and eight salt

vats at Upwich, valued at 80_l._ per annum, with three quarters of

a vat in Northwich for 21 years, in payment for the work. It is

interesting to compare these terms with those on which some of our

modern streams have been deepened and improved.
