A more important work than that of the warehouse at the mouth of the river was now to be begun. This was the building of a vessel above the cataract. The small craft which had brought La Motte and Hennepin with their advanced party had been hauled to the foot of the rapids at Lewiston, and drawn ashore with a capstan to save her from the drifting ice. Her lading was taken out, and must now be carried beyond the cataract to the calm water above. The distance to the destined point was at least twelve miles, and the steep heights above Lewiston must first be climbed. This heavy task was accomplished on the twenty-second of January. The level of the plateau was reached, and the file of burdened men, some thirty in number, toiled slowly on its way over the snowy plains and through the gloomy forests of spruce and naked oak trees; while Hennepin plodded through the drifts with his portable altar lashed fast to his back. They came at last to the mouth of a stream which entered the Niagara two leagues above the cataract, and which was undoubtedly that now called Cayuga Creek. [Footnote: It has been a matter of debate on which side of the Niagara the first vessel on the Upper Lakes was built. A close study of Hennepin, and a careful examination of the localities, have convinced me that the spot was that indicated above. Hennepin repeatedly alludes to a large detached rock rising out of the water at the foot of the rapids above Lewiston, on the west side of the river. This rock may still be seen, immediately under the western end of the Lewiston suspension-bridge. Persons living in the neighborhood remember that a ferry-boat used to pass between it and the cliffs of the western shore; but it has since been undermined by the current and has inclined in that direction, so that a considerable part of it is submerged, while the gravel and earth thrown down from the cliff during the building of the bridge has filled the intervening channel. Opposite to this rock, and on the east side of the river, says Hennepin, are three mountains, about two leagues below the cataract.--_Nouveau Voyage_ (1704), 462, 466. To these "three mountains," as well as to the rock, he frequently alludes. They are also spoken of by La Hontan, who clearly indicates their position. They consist in the three successive grades of the acclivity: first, that which rises from the level of the water, forming the steep and lofty river bank; next, an intermediate ascent, crowned by a sort of terrace, where the tired men could find a second resting-place and lay down their burdens, whence a third effort carried them with difficulty to the level top of the plateau. That this was the actual "portage" or carrying place of the travellers is shown by Hennepin (1704), 114, who describes the carrying of anchors and other heavy articles up these heights in August, 1679. La Hontan also passed the falls by way of the "three mountains" eight years later.--La Hontan, (1703), 106.
