As in a subsequent part of this Memoir, we shall have occasion to detail with some minuteness, the particulars, on all these heads, of the route finally adopted and perfected, our readers will feel that analagous details here would be superfluous. Suffice it here to say, that upon striking an average of the various estimates of the cost of introducing and distributing the Croton water, the Commissioners report it at five and a half millions of dollars.

They next estimate the source and amount of revenue. Proceeding upon the facts furnished, and by the experience of other cities, both in the United States and Europe, and upon calculations founded in most cases upon information derived from personal inquiry at the houses, hotels, taverns, livery stables, shipping, &c.j as to the amount annually paid for water obtained from the water carriers, and other sources of supply, and as to the sum that would willingly be paid for water, if brought to the premises or establishments of the persons inquired of, the Commissioners compiled the table, on the following page, relative to the probable receipts from the Croton water.

After entering into copious details in justification of their estimate, they still further

justify their calculation by this statement.

An opinion is gaining ground with many of those who require large quantities of water for conducting their business, that the supply on this island is annually diminishing. The Commissioners have understood that at the chemical works on the North river, at 33d street, and at an extensive turpentine distillery on the East river, some distance above the Alms House, water cannot be procured in sufficient quantity from the large wells on their premises, where but a few years past, it was obtained in abundance j and, consequently, they are now compelled to cart a portion of their water from a distant place on the island.
