trees, After rowing feveral miles, we 

 pa fled another water-fall, which is longer 

 and more dangerous than the preceding one. 



Giants-pots *, which I have defcribed 

 in the memoirs of the Royal Sivediff} Aca- 

 demy of Sciences, are abundant near the fall 

 of the rock which extends acrofs the river. 

 The rock was almoft dry at preient, the 

 river containing very little water at this lea- 

 fon of the year. Some of the giants-pots 

 were round, but in general they were ob- 

 long. At the bottom of molt of them 

 lay either ftones or grit, in abundance. Some 

 were fifteen inches in diameter, but lb me 

 were lefs. Their depth was likewile diffe- 

 rent, and fome that I obferved were above 

 two foot deep. It is plain that they owed their 

 origin to the whirling of the water round a 

 pebble, which by that means was put in 

 motion, together with the fand. 



We intended to have gone quite up 

 to Fort JSlicholfonm the canoe, which would 

 have been a great convenience to us ; but 

 we found it impoflible to get over the upper 

 fall, the canoe being heavy, and fcarce any 

 water in the river, except in one place where 

 it flowed over the rock, and where it was 

 imroflible to get up, on account of the 



fleep-
