A considerable quantity is also supplied to fountains, or hydrants, on the side-walks, and in the alleys, or closes.

The Cranston Hill Works, made many and costly experiments, as to the best mode of filtering the water, which they, too, drew from the Clyde, and eventually so impaired the capital of the company, that in 1834 they were fain to sell out to the Glasgow Company. The experience thus dearly purchased, was, however, productive of benefit to the community, for the water now supplied, about 3,500,000 gallons daily, is thoroughly filtered.

Greenock, which may be called the seaport town of Glasgow, is most prodigally supplied with water, and, like Edinburgh, without the intervention of machinery, being situated at the foot of mountains, from which issue numerous streams. Mr. Thorn, a skilful engineer, in 1824, devised a plan by which he gathered into vast reservoirs various

mountain rills, and after passing them through filters, conducted them in great profusion

to all parts of the town ; and not only furnished in this way, water for all domestic uses, but enough for the operations of several mills. The filtering reservoirs are 200 feet above the level of the town. The receiving reservoirs are capable of containing 700,000,000 cubic feet. The number of inhabitants of Greenock is 25,000, receiving each two cubic feet, or about fourteen and one-tenth gallons daily.

Paris will next occupy our attention and considering the skill in all departments of engineering, which on all hands is acknowledged to belong to the French, it is remarkable that their capital, and, as it is often called, and really considered, the capital of Europe, is so much behind England in its contrivances for an adequate supply of water.
