Below, the channels unite, and in one deep stream the waters flow on gently between the quarried cliffs of fine black marble, which rise in some places from thirty to seventy feet in height, and are beautifully stratified. Many fossils are imbedded in the rocks, among which the _trilobite_ is quite plentiful. Here the heads (so exceedingly rare) are frequently found. By the contribution of a York shilling to an intelligent lad who kept "watch and ward" at a flight of steps below the bridge, we procured his permission to descend to the rocks below, and his services as guide to the "Big Snake" and the "Indian Cave." The former is a petrifaction on the surface of a flat rock, having the appearance of a huge serpent; the latter extends through the small island from one channel to the other, and is pointed out as the place where Cooper's sweet young heroines, Cora and Alice, with Major Heyward and the singing-master, were concealed. The melody of a female voice, chanting an air in a minor key, came up from the cavern, and we expected every moment to hear the pitch- pipe of David and the "Isle of Wight." The spell was soon broken by a merry laugh, and three young girls, one with a torn barege, came clambering up from the narrow entrance over which Uncas and Hawk Eye cast the green branches to conceal the fugitives. In time of floods this cave is filled, and all the dividing rocks below the main fall are covered with water, presenting one vast foaming sheet. A long drought had greatly diminished the volume of the stream when we were there, and materially lessened the usual grandeur of the picture. We passed the Sabbath at the falls. On Monday morning I arose at four, and went down to the bridge to sketch the cascade. The whole heavens were overcast, and a fresh breeze from the southeast was driving portentous scuds before it, and piling them in dark masses along the western horizon. Rain soon began to fall, and I was obliged to retreat under the bridge, and content myself with sketching the more quiet scene of the river and shore below the cataract. We left Glenn's Falls in a "Rockaway" for Caldwell, on Lake George, nine miles northward, at nine in the morning, the rain falling copiously. The road passes over a wild, * * This view was taken from under the bridge, looking down the river. The noted cave opens upon the river just below where the figures stand. Williams's Rock.--Approach of Dieskau.--Hendrick, the Mohawk Sachem. 106 broken, and romantic region. Our driver was a perfect. Jehu. The plank road (since finished) was laid a small part of the way, and the speed he accomplished thereon he tried to keep up over the stony ground of the old track, to "_prevent jolting!"_
