Note 3 — Chapter IV

I have purposely avoided stating whether Radisson went by way of Lake Ontario or the Ottawa. Dr. Dionne thinks that he went by Ontario and Niagara because Radisson refers to vast waterfalls under which a man could walk. Radisson gives the height of these falls as forty feet. Niagara are nearer three hundred; and the Chaudière of the Ottawa would answer Radisson's description better, were it not that he says a man could go under the falls for a quarter of a mile. "The Lake of the Castors" plainly points to Lake Nipissing.
