We travel about 2 miles and | with tliese appearances ; and then come perpendicular rocks, which appear to be laid up like y^ most exact hewn stone of different widths, and lengths -- and perfectly square. These works become nigher together until they are witliin 9 feet of each other, both at toj) and bottom, The gulf, or walls, are here 100 feet perpendicular. We are now 30 rods from the fall, which is about 50 feet ; but ye bottom of y^ gulf being tilled with water, I could proceed no farther. I could look up into tiiis awful place about 10 rods before there was any bend in the gulf -- and then it appeared to be a right angle. Those rocks for about thirteen rods, appear to be laid up with hewn stones, entirely perpendicular, and more perfect than is in t!ie power of man. Such a place as this baffles all description. The stones are in general from one to 4 feet wide in front, and from 3 to 10 inches thick. From the bottom layers of these perpendicular walls, I knocked off pieces of the stones containing sea-shells of various kinds -- and there is every appearance that the whole of those rocks are composed of shells. These are not lime-stones in general ; but of a consistency between clay and flint, and are exceeding liard and thick, I think that the pliilosopher and the historian will be puzzled to account for those facts. Surely they open a wide field for contemplation, and conjecture. In examining the above gulf, I was happy in having tlie company and assistance of Major Bush and Capt. Clap. Capt. Clap has been in town 2 or 3 years ; Major Bush is now making preparations to remove his family next winter.
