A small additional supply is doubtless obtainable from Byram river, if it were not necessary, in availing of it, to resort to the territory as well as the waters of another State.

The running supply of the Bronx was ascertained on the 4th and 5th of September. It was necessary to repeat the guaging several times in order to separate the accidental flow of the mills from the regular discharge of the river. The latter, however, was at

length satisfactorily ascertained, viz. 4,331,880 gallons and reducing this in the ratio of ;

one-fifth, for the reason heretofore mentioned, we get 3,465,504 gallons as the daily summer flow in seasons of extreme drought. Add to this, the quantity above estimated from the Rye Pond reservoir, = 2,286,900 gallons, and we have the aggregate of 5,752,404 as the amount of all that can safely be depended upon from this quarter."

Tn communicating the Report to the Common Council, the Commissioners strongly

urge the importance to the health, security, and comfort of the city, of an adequate supply of pure water. " The " of the utility," say they, undertaking being acknowledged, as the Commissioners believe it is, by a large majority of the citizens, the only questions of importance which can arise on the subject, are, first, the source from which the water is to be brought second, the manner of bringing it and third, the difficulties to be encountered, ; ;

and the expense of the project. With the information in the possession of the Corporation, should they decide to carry the project into effect, the first and second considerations may safely be left to the judgement of those who shall be selected to superintend and direct the operations. The difficulties to be encountered, are much less in the opinion of the Commissioners, than those which have been overcome, both in this county and in Europe.
