 terminus for the southern section of the river. The whole distance of eighty miles is not a continuous rapid, but eleven or twelve more or less impracticable sections occur in it, so that no great length of navigable water is found at any place. As its name suggests, the Grand Rapid is the main rapid of the river, and has a fall of seventy or eighty feet. This fall occurs mostly within a distance of half a mile, though the total length of the rapid is about four times that. The upper part is divided by a long narrow island into two channels, and it is through these comparatively narrow spaces that the cataract rushes so wildly. Above and below the island, the river may with great care be navigated by the loaded scows, but the water upon either side is so rough that goods cannot be passed down or up in safety. The method of transportation adopted is as follows: About a mile above the island, at the head of the rapid, the steamer Athabasca ties up to the shore. There she is met by a number of flat-bottomed boats or scows capable of carrying about ten tons each, and to these the boat's cargo is transferred. When loaded the scows are piloted one by one to the head of the island in the middle of the river, where a rough wharf is built, and to it all goods are again transferred, whence they are carried to the lower end of the island by means of a tramway. The unloaded scows, securely held with ropes by a force of men on the shore, and guided with poles by a crew on board, are then carefully lowered down stream to the foot of the island, where they again receive their loads. Accidents frequently happen in passing down the unloaded scows, for the channel (the eastern one always being chosen) is very rough and
