feet. Partly under this bridge, and about 10 or 12 

 feet below it, is another, which is wider, but not 

 long; for at the east end they form one body of 

 rock, 12 or 14 feet thick, and under this the water 

 Hows, It is evident, from the appearance of the 

 rocks, that the water, in some plates, fomnerly flowed 

 40 01' 50 feet above its present bed. Many cavities^ 

 of different figures and dimensions, but generally cir- 

 cular, are worn out in the rocks. One of these ia

 four or five teet deep ; the rock is on one Tside worn 

 through at the bottom. A Httle above the briclge, 

 on the west side of the chasm, is a cave or littlfe

 are mostly white, though in some places clouded or

 added to the terrific noise within, has hitherto pre-
