a man of worth and great skill in natural 
hi (lory, and his little piece befidcs the candour 
and veracity of the writer, derives a great value 
from its being the only account in our language 
of this ftupendous objed. T. Charlevoix an 
Author of good credit, ( 'where the inter ejl af 
his nation and religion are unconcerned) has 
given us a defer iption perfectly agreeable to 
Mr. Malm% tho’ much lefs circumftantial : 
It was in 1722, he was on the fpot, and the 
heights had not then probably been taken by 
inftruments, for he feerns to think it very diffi- 
cult if poffible • He gueOes the great Fall to 
be, 1 40 or 1 50 feet from a meafure taken by 
founding ; and adds, that he has feen finall 
birds flutter juft above the fall itfelf we have 
likewile an account of this cataract ‘Phil. Trans . 
N c . 1. p. rip. from Mi\ Ecrtifjdn tranfmitted 
by Mr. Dudley. Mr. BoruJJan relates that the 
Governor of Canada's fbn the Marquis de Ca- 
vagnal had founded it, a.nd fixed the perpen- 
dicular fall at ari fathom, this was alio in 1722.

are conlcious their enjoyment of this Fort is a. 
manifeft violation of the treaty of Utrecht tho* 
they know the juftice of the EngliJlj Nation. 
will not permit them to com pell the Scneka ' s 
againft their inclination to dillodge them. 
Among other curious parts of Mr. Bart ram's 
journal are his thoughts (thrown together at the 
end) on the Origin of the Aborigines of Ame-
