RUNNING THE RAPIDS. Si 
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.* 
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 suc- 
cessfully 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.

Survey of Canada.
