generally cultivated as grazing farms; the whole presenting an aspect of extraordinary cleanliness. The water is perfectly soft and clear, and fed by such springs, can scarcely be otherwise than pure. The quantity of saline matter, according to the analysis of Chilton, does not exceed two-and-eight-tenths of grains in the gallon.

The Lake.

Having thus disposed of the sources of supply, we, at five miles below the confluence of the Muscoot, arrive at the Lake or Reservoir, which is irregular in shape, and so formed by the variations in the banks of the river and the ob struction to the channel, by the Dam erected at the head of the works. The Lake is four miles in length, and covers an area of four hundred acres, varying in depth from one to fifty feet, and holding an available supply of five hundred millions of gallons above the level, which will allow the Aqueduct to discharge thirty-five millions of gallons per day. About two miles above the Dam, the Lake is crossed by Pine's Bridge, at a location and crossing well-known as such in the revolutionary history of the County. The beauty of this sheet of water strikes every visitor with pleasure, while the cleanliness of the banks reflect credit on the keeper of this portion of the works, as well as on the precautionary measures, adopted by the projectors of this magnificent undertaking, to preserve the banks from the encroachments of the adjoining owners, or the evils to be apprehended from the designs of the vicious.

The Dam.

This structure, on the stability of which, perhaps, more depends, thau on any other part of the work, is built of interlocked wood and stone-work, of sufficient strength to withstand the pressure of the immense body of water in the Lake, rises to the height of forty feet above the rocky bed of the river, which at this point is two hundred and eighty feet wide. The face of the Dam. built of cut granite, is in two sections or parts, the east of which is ninety feet wide, having a fall of forty feet; the western division has a fall of the same height, with a width of one hundred and eighty feet, over a beautifully formed facing of an ogee shape. Between the divisions of this structure, a pier forms the foundation for the gate-house and sluice-way for relieving the structure of its pressure from the Lake, or for the discharge of the waters during the repairs which may be required on the Dam, or the aprons of hewn timber which receive the water after the overflow. The gate-house is reached by a bridge from the eastern shore, running parallel with the Dam immediately over the lip. The waters after leaving the aprons, overflow a gravelled bed for about two hundred feet, at the extremity of which they are again broken by a brush dam composed of hemlock logs, after passing which the river flows on in its natural channel until it reaches the Hudson, at about six miles from this point. Over the brush dam, and about three hundred feet below the face of the main structure, a bridge has been erected for the convenience of travellers, and from a position on which, the fall over the Dam is received with the most facility and to the greatest advantage-the water, in its passage over the Dam, presenting a beautiful lacework-like appearance, and eliciting the admiration of the visitor. By far the greater and most difficult part of this structure is hidden from the view, but sufficient will be found in this part of the work to arrest the attention of the tourist, and will repay the admirer of the beautiful in art and nature, for his trouble in reaching this sequestered spot.
