It was with regret that we turned our backs on Chesuncook, which McCauslin had formerly logged on, and the Allegash lakes. There were still longer rapids and portages above; among the last the Rippogenus Portage, which he described as the most difficult on the river, and three miles long. The whole length of the Penobscot is two hundred and seventy-five miles, and we are still nearly one hundred miles from its source. Hodge, the assistant State Geologist, passed up this river in 1837, and by a portage of only one mile and three-quarters crossed over into the Allegash, and so went down that into the St. John, and up the Madawaska to the Grand Portage across to the St. Lawrence. His is the only account that I know, of an expedition through to Canada in this direction. He thus describes his first sight of the latter river, which, to compare small things with great, is like Balboa's first sight of the Pacific from the mountains of the Isthmus of Darien. "When we first came in sight of the St. Lawrence," he says, "from the top of a high hill, the view was most striking, and much more interesting to me from having been shut up in the woods for the two previous months. Directly before us lay the broad river, extending across nine or ten miles, its surface broken by a few islands and reefs, and two ships riding at anchor near the shore. Beyond, extended ranges of uncultivated hills, parallel with the river. The sun was just going down behind them, and gilding the whole scene with its parting rays."

About four o'clock, the same afternoon, we commenced our return voyage, which would require but little if any poling. In shooting rapids the boatmen use large and broad paddles, instead of poles, to guide the boat with. Though we glided so swiftly, and often smoothly, down, where it had cost us no slight effort to get up, our present voyage was attended with far more danger: for if we once fairly struck one of the thousand rocks by which we were surrounded the boat would be swamped in an instant. When a boat is swamped under these circumstances, the boatmen commonly find no difficulty in keeping afloat at first, for the current keeps both them and their cargo up for a long way down the stream; and if they can swim, they have only to work their way gradually to the shore. The greatest danger is of being caught in an eddy behind some larger rock, where the water rushes up stream faster than elsewhere it does down, and being carried round and round under the surface till they are drowned. McCauslin pointed out some rocks which had been the scene of a fatal accident of this kind. Sometimes the body is not thrown out for several hours. He himself had performed such a circuit once, only his legs being visible to his companions; but he was fortunately thrown out in season to recover his breath. In shooting the rapids, the boatman has this problem to solve: to choose a circuitous and safe course amid a thousand sunken rocks, scattered over a quarter or half a mile, at the same time that he is moving steadily on at the rate of fifteen miles an hour. Stop he cannot; the only question is, where will he go? The bow-man chooses the course with all his eyes about him, striking broad off with his paddle, and drawing the boat by main force into her course. The stern-man faithfully follows the bow.

We were soon at the Aboljacarmegus Falls.
