I WILL endeavour to improve a little, upon the description above, of our grand water-works; and give you, in a small compass, their present state. The place is named

FAIR MOUNT.

SUPPLY.

3 Wheels in motion, 15, 16, 16, feet diameter. The Shafts, of iron, weight five tons each, connected with

3 double Forcing pumps,

connected with

3 iron Mains, sixteen inches diameter, two hundred and eighty-six feet long, discharging into

2 Reservoirs, contents seven millions gallons.

Height of reservoirs,

102 feet above Schuylkill low-water at Fair

Mount;

Quantity of water every twenty four hours, raised by these three wheels in mo

1 large iron distributing Main, from Fair Mount to the intersection of Broad Street and Chestnut Street, viz.

2661 feet, of 22 inches diameter, runrunning from Fair Mount to Callowhill and Broad Streets.

6909 feet, of 20 inches diameter, running along Broad Street North, to Chestnut Street.

9570 feet of Main.

Pipes from this Main, are laid along Chestnut Street, through to Water Street, Delaware, also along other streets in part, and are to be laid throughout. Diameter from six to eight inches.

The old wooden pipes measured in length, through the streets of the city, about thirtytwo miles. These are, from time to time, as they decay, to be replaced with iron ones, which will be extended likewise into the Liberties, N. and S.

Total cost of these works, at their present extent of machinery and pipes, Doll. 426,330

The site of them, is designated on a small map, here affixed, of the city of Philadelphia and environs. And, in order to convey a better impression of the spot, and some of its interesting objects, than my bare mention of them may perhaps do, I have also here annexed, an engraved view of Fair Mount.

FOR Some of my Statistical representations, I am indebted to the elaborate work of Doctor Adam Seybert.

I could wish that gentleman were induced to give the public a second or supplementary edition. There is, in the occurrences of the few years which have already elapsed, together with what is now occurring, and very soon will occur, matter sufficient to form an interesting, and very useful addition to the work, as published in 1818.
