VIEW IN HOLLAND.

Holland is one of the most remarkable countries on the globe. The peculiarities which make it remarkable arise from the fact that it is almost perfectly level throughout, and it lies so low. A very large portion of it, in fact, lies below the level of the sea, the waters being kept out, as every body knows, by immense dikes that have stood for ages.
Indeed, the dikes alone would not prevent the country from being inundated; for it is not possible to make them perfectly tight, and even if it were so, the soil beneath them is more or less pervious to water, and thus the water of the sea and of the rivers would slowly press its way through the lower strata, and oozing up into the land beyond, would soon make it all a swamp.
Then, besides the interpercolation from the soil, there is the rain. In upland countries, the surplus water that falls in rain flows off in brooks and rivers to the sea; but in land that is below the level of the sea, there can be no natural flow of either brooks or rivers. The rain water, therefore, that falls on this low land would remain there stagnant, except the comparatively small portion of it that would be evaporated by the sun and wind.
Thus you see, that if the people of Holland were to rely on the dikes alone to keep the land dry, the country would become in a very short time one immense morass.
To prevent this result it is necessary to adopt some plan to raise the water, as fast as it accumulates in the low grounds, and convey it away. This is done by pumps and other such hydraulic engines, and these are worked in general by wind mills.
