Documentary History of the State of New York, Vol. III
The cord hung perpendicular, and I was then 24 feet from the base of the rock. The cord measured 155 by a square. 15 rods below the falls, the perpendicular rock is about 40 feet higher than where we measured. At the bottom where the water strikes, it is 120 feet wide. About 25 rods below this, there is a place where it is possible for people to get down; but extremely steep, and something dangerous; but we passed down without injury. At y« bottom of y^ river there is } ^ same rock --which rock extends all over this counly; how deep, no one can tell. The rock is a great curiosity; i'L is all aliinesloMe,and is tilled with every kind of sea-shells, petrified. I knocked out of yc solid rock, 155 feet below the surlace of the earth, various shells, which may now be seen. This gulf is without any iloubt all made from f'^s of a mile below by the wearing of the water, which makes the curiosity of the shells vastly greater. And, indeed, this whole rock, which is certainly 155 feet dee[). ai.d which extends to Sandy Creek-- and perliaps 50 or 100 miles round in all directions, made up of sea-shells of every kind,-- as cockles, clams, oysters, and a thousand others. At Zadock Bush's.
14/A.-- Rode about 2 miles to another gulf upon a small creek in Lowville. The Ml is about 70 feet, among clay rocks. Tliese rocks are singular. They aj.pear to be laid up in the most exact and curious manner. The stones in some places in couises of 4 feet wide, are an inch, and half inch square at the ends, and may be taken out about 8 inches long, in y« shape of horn s-- and tliey are said indeed to be most excellent hones; others ai-e 2, 3, and 4 feet wide, and from G to 12 inches thick.
