of the river banks, from three to five hundred feet in height, presents the appearance of running tar, and here and there tar wells are found, having been formed by the accumulation of the viscid tar in natural receptacles of the rock. Thus collected it has been commonly made use of by workmen in the calking of the scows on the river.[1]
Sixteen miles farther down, the Boiler Rapid, so called from the fact that in 1882 a boiler intended for the steamer Wrigley was lost in it, was successfully run on the following day, and early in the afternoon the third rapid was reached. In attempting to run it on the left side, we found, after descending perhaps half-way, that there were too many rocks in the channel ahead, and therefore an effort was made to cross to the right side, which looked to be clearer. My brother's canoe, steered by old Pierre, avoided all rocks and was taken successfully across, but mine was not so fortunate. In attempting to follow, we struck a large rock in mid-channel, but happily the collision occurred in such a way that my canoe was not seriously damaged. It was merely whirled end for end in the current and almost filled with water, though not quite sufficiently to sink us. Leaving the two Indians to pull for the shore, I seized a tin kettle and lost no time in dashing out some of the water. After a sharp struggle we managed to land. Of course all we had in the canoe—instruments, blankets, provisions and clothing—was soaked, and it was therefore necessary to unload and turn everything out.
