    west side of the ravine named, the raceway would be con- structed around the course of the high ground along the north or left bank of Tiffany's run, and south of the dwelling of Mr. Richards, to the distributing reservoir. The entire distance (by line) of works proposed, is not over 4500 feet, and I am confident, (having lately examined the route) it is by no means a difficult or expensive one. The level of the lake in Herring Run being spme 10 feet higher than the Tiffany lake, a canal or raceway of small transverse area for water-way will be sufficient to pass a large amount of water; but I propose the area for water-way in the raceway shall be sufficient for the passage of from one and a half to two millions gallons per day; so that every advantage of a rise of the waters in Herring Run may be availed of for filling the Tiffany valley reservoir, as well as the lake in Herring Run. The reservoir in the valley of Tiffany's Run, I propose to be constructed as per plans recommended in my former com- munication relative to the same, or per plans as recommended by Mr. Sickels, raising, of course, the dam or embankments higher and having more extensive excavations according to increased area. For the line of works through the dividing ridge between the valley of Tiffany's Run and Homestead valley, I recommend it should pass through the same, near the dwelling of Mr. Tiffany, by cut and tunnel, and terminate by conduit in the valley of Homestead, near what is known as Patterson's place on the north of the valley and within some 2500 feet of the city limits.
