This natural arch affords a striking illustration of the wearing effect of water. The waves constantly washing and often beating in fury upon the line of sandstone cliffs has, in the course of ages, { 209} hollowed this arch at the point where the rock was softest. The immense amount of material thus washed from the face of the cliffs has been thrown ashore, blown along the coast, and heaped up in the sand-hills which Radisson describes, and which are reliably reported to vary from one hundred to three hundred feet in height.
A few days later the party came to a place where they made a portage of some miles, in order to save going around a peninsula jutting far out into the lake. "The way was well beaten," says Radisson, "because of the comers and goers, who by making that passage shortens their journey by 8 dayes." From this circumstance it is evident that our travelers were on a frequented route, and that the Indians knew enough of the geography of the country to avoid a canoe journey of several hundreds of miles, by carrying their light craft and their goods across the base of the peninsula, which is here very narrow, being almost cut in two by a chain of lakes and rivers.[3]
Radisson was told that "at the end of the point there is an isle all of copper." This is not very far from the truth, for this peninsula contains, about Keweenaw Point, the richest copper deposit in the world. In 1857 there was taken from one of the mines a mass of ore weighing 420 tons and containing more than ninety per cent of pure copper.
Traveling on, the party met with some Christinos, or Crees, who joined it "in hopes," says Radisson, "to gett knives from us, which they love better then we serve God, which should make us blush for shame." In time they came to "a cape very much elevated like piramides," probably the "Doric Rock." In a certain "channell" they took "sturgeons of a vast bignesse and Pycks of seaven foot long," probably the well-known muscalonge.[4]
Now the long canoe voyage had come to an end, and as the Indians said that five days' journey would be needed to bring them to their homes, and the two white men had heavy packs which they were loth to carry so long a distance, they { 211} decided to remain where they were and let their red friends either come or send back for them. Then, being but two men, surrounded by wild tribes, they built themselves a little triangular log fort by the water-side, with its door opening toward the water. All around it, at a little distance, was stretched a long cord, to which were fastened some small bells, "which weare senteryes" (sentries), Radisson says.[5]
