It is clear, then, that the portage was on the east side, whence it would be safe to conclude that the vessel was built on the same side. Hennepin says that she was built at the mouth of a stream (_riviere_) entering the Niagara two leagues above the falls. Excepting one or two small brooks, there is no stream on the west side but Chippewa Creek, which Hennepin had visited and correctly placed at about a league from the cataract. His distances on the Niagara are usually correct. On the east side there is a stream which perfectly answers the conditions. This is Cayuga Creek, two leagues above the Falls. Immediately in front of it is an island about a mile long, separated from the shore by a narrow and deep arm of the Niagara, into which Cayuga Creek discharges itself. The place is so obviously suited to building and launching a vessel, that, in the early part of this century, the government of the United States chose it for the construction of a schooner to carry supplies to the garrisons of the Upper Lakes. The neighboring village now bears the name of La Salle. In examining this and other localities on the Niagara, I have been greatly aided by my friend, O. H. Marshall, Esq., of Buffalo, who is unrivalled in his knowledge of the history and traditions of the Niagara frontier.] Trees were felled, the place cleared, and the master-carpenter set his ship-builders at work. Meanwhile two Mohegan hunters, attached to the party, made bark wigwams to lodge the men. Hennepin had his chapel, apparently of the same material, where he placed his altar, and on Sundays and saints' days said mass, preached, and exhorted; while some of the men, who knew the Gregorian chant, lent their aid at the service. When the carpenters were ready to lay the keel of the vessel, La Salle asked the friar to drive the first bolt; "but the modesty of my religious profession," he says, "compelled me to decline this honor."
