138 Account of a Remarkable Storm. 
great Polentte and produced ravages not less remarkable. 
de of the Kaaterskill, about three and a half 
miles from the. town, a small brook empties into that stream. 
This breok-is usually from one to two feet in width, and does 
notcontain more water than might pass rons a  eylindrieal 
tube of six or eight inches in diameter. The distance from 
the source of the brook to its mouth is about eos quarters 
ofamile. The country bordering it is hilly. In the after- 
noon and evening of the storm the brook was enlarged to a 
Suen extent. For halfa mile from its mouth upwards, 
t e from two to four rods in width, except in certain 
hing Ww te it was six, eight, and ten rods wide. In some 
places it was twenty feet deep. The quantity of tn and 
stones, and rocks in rolled masses, washed out of the banks, 
during the afternoon, was prodigiously great, It has been 
estimated by several judicious persons, to exceed a hundred 
thousand tons. The average width of the ravine, I estima- 
to be four or five rods. I am not confident of the ex- 
actness of these estimates, nor are they intended to be very 
exact y as relatesto the quantity. In some places, 
s rocks washed out of the banks, have been heaped up 
by the ia ag a to the height of from ten to fifteen feet, and 
several rods in width. A considerable number of these 
rocks are calmicd to weigh from six to ten tons each. I 
measured one, which was ten feet in length, seven feet in 
breadth, and eighteen inches in thickness. This rock, 
which is a mass of compact carbonate of Rot is almost
