III. An Account of the Falls of the ^her Niagara, 
taken at Albany, 0(5lob. lo. i/is. from 
Monfieur Boralfaw , a French Flatiye of 
Canada, ©y the Honourable Paul Dudley, 
F. R. S> 
T he Falls of t^iagira are a mighty Ledge or Preci- 
pice of folid Rock, that lies acrofs the whole 
breadth of the River (a little before it empties it felf' 
into, or forms the Lake Ontario) and very deep; 
Monfieur Boraffaw never meafur’d the Falls himfelfi 
though he has been there at feven different Times : 
But what he fays is. That, 
This laft Spring the Governour of Canada^ Mon- 
fieur f^Audreil, ordered his own Son, with three other 
Officers, vfz. Meflieurs Longue I[le, St. Fille^ and 
Lauhineau to Survey Niagara, and take the exad: 
height of the Catarac3', which they accordingly did 
with a Stone of half an hundred Weight, and a large 
Cod-line, and found it upon a Perpendicular no more 
than twenty fix Fathom; his W'ords were Fingt ^ 
Six Bras. 
This differs very much from the Account Fatlier 
Tdemepin has given the World of that Catarad, for he^ 
makes it an hundred Fathom ; and our Modern Maps , 
from him, as I fuppofe, mark it at fix hundred Feet ; . 
but I believe Hciamftn never meafured it, and there: 
is no gueffing at fuch Things.. 
When?
