sons' Kiver and between that and Fort Walsh. Between Fort Walsh 
and Old Wives' Lake, too, more than half of the country was burnt. 
At several points along the river where we camped, I made small col- 
lections of various species of locusts and other insects. These were 
found close to the river on little spots somewhat isolated from the other 
country, and hence were not reached by fires. 
From the scarcity of all classes of insect life in these burnt districts, 
it would appear that the fires destroy the insects in great numbers. 
But whether this is done in time to prevent the depositing of eggs, or 
not, I did not learn. I found many charred bodies of locusts that ap- 
parently belonged to several species. Some of these contained eggs, 
and others were still in coition. They were too much disfigured, in most 
cases, to tell with certainty the species to which they belonged. 
During the journey down the river, short excursions were made back 
into the country at six different points. These were from three to six 
miles in length, but disclosed nothing in reference to the Rocky Mountain 
locust, more than to give us an idea of the surface of the country. We 
were thus enabled to make comparisons, from time to time, of the coun- 
try now being traversed with that already passed over. Although the 
general features of the entire country were those heretofore mentioned, 
we could discern a slight variation, from time to time, both in the veg- 
etation and soil. The farther down we went the more sage-brush was 
seen. This sage is not the same as the sages of Wyoming and Utah, 
but more nearly resembles Artemisia ludoviciana. It grows more abun- 
dantly on sandy soil comparatively free from rocks. Several other 
Arteinisias are also occasionally met with, but these are small and in- 
conspicuous. 
At a point about twelve miles above the mouth of Bow River, on the 
south side, the upland is quite sandy, and much pawed over by buf- 
falo. Of course, this has been done several years ago, as there are but 
few of those animals left in the country at the present time. At various 
other points also there is very similar soil, one of these being several 
miles to the northward of Medicine Hat, or the crossing of the Sas- 
katchewan at the mouth of Seven Persons' River. At this latter locality 
we hired a man with his team to take us across country to the terminus 
of the Canadian Pacific Railroad. Our route lay through the Cypress 
Hills to Fort Walsh, and thence eastward for some forty-odd miles, 
after which we turned to the northeast and traveled in that direction 
until we struck the surveyed line of the Canadian Pacific Railroad, near 
Rush Lake, after which we again turned east. 
In making this journey a great diversity of country was passed over 
and a distance of about 300 miles traveled. During the first day we 
followed up the course of a small coulee that extends back from the 
Saskatchewan to the Cypress Hills, part of the time keeping the high 
land and at other times choosing the valley. Here also the surface 
was bared of its vegetation, save in a few isolated spots, by prairie
