WESTERN PARTS of PENNSYLVANIA. 229 



a circumftance which attends tlie falls of Chenefcco, as 

 well as thofe of Niagara. 



A fmgular appearance is obferved at thefe falls, which 

 has never perhaps been noticed by any writer. Imme- 

 diately below the great pitch a commixture of foam aiid 

 water is puffed up in fpherical figures, about the fize of 

 a common haycock. They burit at the top, and difcharge a 

 column of fpray to a prodigious height ; they then fub- 

 fide, and are fucceeded by others which exhibit the fatne 

 appearances. 1 hefe fpherical forms are moff confpicuous 

 about midway between the weft: fide of the flreight, and 

 the ifland which divides the falls, and where the lareeft 

 column of water defcends. This appearance is produced 

 by the afcenfion of the air, which is carried down by the 

 column of falling water in great quantities CO the bed of 

 the river. 



The river at the falls is about feven hundred and forty 

 three yards wide, and the perpendicular pitch is one 

 hundred and fifty feet in height. In the lafl half miFe 

 immediately above the falls the defcent of the water is 

 fifty eight feet ; but the difficulty which would attend 

 the bufinefs, prevented me from attempting to level the 

 rapids in the chafm below ; though from conjecture, I 

 concluded that the waters mull defcend at leaft fixty five 

 feet, and from thefe refults it appears that the water falls 

 about two hundred and feventy three feet, in the dif- 

 lance of about feven miles and an half.

 Your friend,
