The western division consists of low fen or clay soil and presents a monotonous expanse of rich meadow-land, carefully drained in regular lines of canals bordered by stunted willows, and dotted over with windmills, the sails of canal craft and the clumps of elm and poplar which surround each isolated farm-house.
Following the example of the great Kampen irrigation canal in Belgium, artificial irrigation is also practised by means of some of the smaller streams, especially in North Brabant, Drente and Overysel, and in the absence of streams, canals and sluices are sometimes specially constructed to perform the same service.
The main ditches, or canals, afterwards also serve as a means of navigation.
In addition, various kinds of canals and endiked or embanked lakes had come into existence, forming altogether a vast network of more or less stagnant waters.
In time of drought the water in the canals and boezems is allowed to run back into the polders, and so serve a double purpose as water-reservoirs.
The united length of the canals exceeds 1500 m.
After 1849 the canal programme was again taken up by the state, which alone or in conjunction with the provincial authorities constructed the Apeldoorn-Dieren canal (1859-1869), the drainage canals of the " Peel " marsh in North Brabant, and of the eastern provinces, namely, the Deurne canal (1876-1892) from the Maas to Helenaveen, the Almelo (1851-1858) and Overysel (1884-1888) canals from Zwolle, Deventer and Almelo to Koevorden, and the Stieltjes (1880-1884), and Orange (1853-1858 and 1881-1889) canals in Drente, the North Williams canal (1856-1862) between Assen and Groningen, the Ems (1866-1876) ship canal from Groningen to Delfzyl, and the New Merwede, and enlarged the canal from Harlingen by way of Leeuwarden to the Lauwars Zee.
The large ship canals to Rotterdam and Amsterdam, called the New Waterway and the North Sea canal respectively, were constructed in 1866-1872 and 1865-1876 at a cost of 21 and 3 million pounds sterling, the former by widening the channel of the Scheur north of Rozenburg, and cutting across the Hook of Holland, the latter by utilizing the bed of the Y and cutting through the dunes at Ymuiden.
In 1876 an agreement was arrived at with Germany for connecting the important drainage canals in Overysel, Drente and Groningen with the Ems canal system, as a result of which the Almelo-Noordhorn (1884-1888) and other canals came into existence.
The canals differ in character in the different provinces.
Again, a totally different character belongs to the canals in North Brabant, and the east and north-east of Holland where, in the absence of great rivers, they form the only waterways which render possible the drainage of the fens and the export of peat; and unite the lesser streams with each other.
Thus in Overysel, in addition to the canals already mentioned, the Dedemsvaart connects the Vecht with the Zwarte Water near Hasselt; in Drente the Smildervaart and Drentsche Hoofdvaart unites Assen with Meppel, and receives on the eastern side the drainage canals of the Drente fens, namely, the Orange canal and the Hoogeveen Vaart (1850-1860; 1880-1893).
In Friesland, finally, besides the ship canal from Harlingen to the Lauwers Zee there are canals from Leeuwarden to the Lemmer, whence there is a busy traffic with Amsterdam; and the Caspar Robles or Kolonels Diep, and the Hoendiep connect it with Groningen.
Other branches of industry include carpet-weaving at Deventer, the distillation of brandy, gin and liqueurs at Schiedam, Rotterdam and Amsterdam, and beer-brewing in most of the principal towns; shoe-making and leather-tanning in the Langstraat district of North Brabant; paper-making at Apeldoorn, on the Zaan, and in Limburg; the manufacture of earthenware and faience at Maastricht, the Hague and Delft, as well as at Utrecht, Purmerend and Makkum; clay pipes and stearine candles at Gouda; margarine at Osch; chocolate at Weesp and on the Zaan; mat-plaiting and broom-making at Genemuiden and Blokzyl; diamondcutting and the manufacture of quinine at Amsterdam; and the making of cigars and snuff at Eindhoven, Amsterdam, Utrecht, Kampen, &c. Shipbuilding is of no small importance in Holland, not only in the greater, but also in the smaller towns along the rivers and canals.
To obtain a correct idea of the trade of Holland, greater attention than would be requisite in the case of other countries must be paid to the inland traffic. It is impossible to state the value of this in definite figures, but an estimate may be formed of its extent from the number of ships which it employs in the rivers and canals, and from the quantity of produce brought to the public market.
Great Britain has many valuable ore beds, some rich in iron, many of them near to beds of coal and to the sea-coast, to canals or to navigable rivers.
The canals of Belgium are scarcely less numerous or important than those of Holland, especially in Flanders, where they give a distinctive character to the country.
The government also did much in the way of improving the internal communications of the country, in repairing the roads and canals, in forming new ones, in deepening and widening rivers, and the like.
Though navigable for a few months only, the rivers of Poland have always been of considerable importance for the traffic of the country, and their importance is further increased by several canals connecting them with the Russian and German rivers.
All these canals are, however, beyond Russian Poland.
Several are navigable, and the facilities for inland water traffic are increased by canals.
The Saone (q.v.), which has received (left) the Doubs, is the real continuation of the Rhone, both from a geographical and a commercial point of view, and it is by means of canals branching off from the course of the Saone that the Rhone communicates with the basins of the Loire, the Seine, the Rhine and the Moselle.
The flank defences of the main wall are insufficient; indeed there is no pretence at scientific structure about any part of the defences; but the site of the city is well chosen for defence, and the water supply (drawn by canals from the Arghandab or derived from wells) is good.
The plains about Kandahar are chiefly watered by canals drawn from the Arghandab near Baba-wali, and conducted through the same gap in the hills which admits the Herat road.
It bears a strong resemblance to a Dutch town, for the houses are built in the style of those of Amsterdam, and the narrow channel separating it from its western suburb of Overzijde and the waters of the Waigat, which intersect it, recall the canals.
It is still, territorially, the largest province of the empire, and includes some of the most fertile lands in the Euphrates-Tigris valleys; but while possessing great possibilities for fertility, by far the larger portion of the vilayet is to-day a desert, owing to the neglect of the irrigation canals on which the fertility of the valley depends.
Wherever there is any pretence at irrigation, along the banks of the two great rivers and by the few canals which are still in existence, the yield is enormous, and the shores of the Tigris and Euphrates in the neighbourhood of Bagdad and Hilla seem to be one great palm garden.
Canals and dikes have been constructed to control and distribute the much-needed water, and the officials are housed in new buildings of substantial appearance.
The settled population lies entirely along the banks of these streams and the canals and lagoons westward of the Euphrates, between Kerbela and Nejef.
Irrigation effected by river-fed canals naturally depends on the regimen of the rivers.
Elsewhere in India the rainfall is usually sufficient for all the cultivation of the district, but about every eleven years comes a season of drought, during which canal water is so precious as to make it worth while to construct costly canals merely to serve as a protection against famine.
When a river partakes of the nature of a torrent, dwindling to a paltry stream at one season and swelling into an enormous flood at another, it is impossible to construct a system of irrigation canals without very costly engineering works, sluices, dams, waste-weirs, &c., so as to give the engineer entire control of the water.
Such may be seen on the canals of Cuttack, derived from the Mahanadi, a river of which the discharge does not exceed 400 cub.
Very differently situated are the great canals of Lombardy, drawn from the Ticino and Adda rivers, flowing from the Maggiore and Como lakes.
India possesses no great lakes from which to draw rivers and canals, but through the plains of northern India flow rivers which are fed from the glaciers of the Himalaya; and the Ganges, the Indus, and their tributaries are thus prevented from diminishing very much in volume.
For this monsoon irrigation there is always abundance of water, and so long as the canals and sluices are kept in repair, there is little trouble in distributing it over the fields.
Closer examination, however, shows that if the prevailing slopes are not more than a few inches in the mile, yet they do exist, and scientific irrigation requires that the canals should be taken along the crests and drains along the hollows.
To the left of the diagram is shown (by firm lines) a system of canals laid out scientifically, and of drains (by dotted lines) flowing between them.
The expense of forming canals, embankments and sluices for warping land is from Do to £20 an acre.
Lombardy is quite as well off as Piedmont for the means of irrigation and, as already said, its canals have the advantage that being drawn from the lakes Maggiore and Como they exercise a moderating influence on the Ticino and Adda rivers, which is much wanted in the Dora Baltea.
It is easy, then, when the Nile is low, to cut short, deep canals in the river banks, which fill as the flood rises, and carry the precious mud-charged water into these great flats.
Mehemet Ali began by deepening the canals of Lower Egypt by this amount, a gigantic and futile task; for as they had been laid out on no scientific principles, the deep channels became filled with mud during the first flood, and all the excavation had to be done over again, year after year.
With a serf population even this was not impossible; but as the beds of the canals were graded to no even slope, it did not follow that if water entered the head it would flow evenly on.
As the river daily fell, of course the water in the canals fell too, and since they were never dug deep enough to draw water from the very bottom of the river, they occasionally ran dry altogether in the month of June, when the river was at its lowest, and when, being the month of greatest heat, water was more than ever necessary for the cotton crop. Thus large tracts which had been sown, irrigated, weeded and nurtured for perhaps three months perished in the fourth, while all the time the precious Nile water was flowing useless to the sea.
The obvious remedy was to throw a weir across each branch of the river to control the water and force it into canals taken from above it.
The river was thus to be emptied, and to flow through a whole network of canals, watering all Lower Egypt.
An essential part of the barrage project was the three canals, taking their water from just above it, as shown in fig.
The heads of the existing old canals, taken out of the river at intervals throughout the delta, were to be closed, and the canals themselves all put into connexion with the three high-level trunk lines taken from above the barrage.
Moreover, in the meantime the eastern, or Tewfikia, canal was dug and supplied with the necessary masonry works for a distance of 23 m., to where it fed the network of old canals.
This had been totally neglected in Egypt; but very large sums have been spent on it, and the country is now covered with a network of drains nearly as complete as that of the canals.
To water the valley, therefore, it is necessary to construct canals having bed-slopes less than that of the river, along which the water flows until its surface is higher than that of the fields.
Occasionally the desert cliffs and slopes come right down to the river, and it is difficult, if not impossible, to carry the higher-level canals past these obstructions.
There being at its head no weir across the Nile, the water in the Ibrahimia canal used to rise and fall with that of the river, and so the supply was apt to run short during the hottest months, as was the case with the canals of Lower Egypt before the barrage was built.
In the famine year1877-1878the area irrigated by productive canals was 5, 1 7 1, 497 acres.
In addition to these great perennial canals, much has been done since 1878 in enlarging and extending what are known as the " inundation canals " of the Punjab, which utilize the flood waters in the rivers during the monsoon season and are dry at other times.
By these canals large portions of country throughout most of the Punjab are brought under cultivation, and the area thus watered has increased from about 180,000 to 50o,000 acres since 1878.
It is on inundation canals such as these that the whole cultivation of Sind depends.

In1877-1878these canals irrigated 241,790 acres.
It should be mentioned in favour of these canals that although the irrigation is not of yearly value, they supply very important water communication through a province which, from its natural configuration, is not likely to be soon intersected by railways.
If, moreover, such a famine were again to occur in Orissa as that of 1866--1867, there would be no doubt of the value of these fine canals.
