from this time they stay together till the rutting season is over 
and it is time to seek the woods once more.” 
Of their curious migration he says, ‘‘They are extremely un- 
certain in their movements, seldom taking the same course in 
two consecutive years, ... this is in a great measure accounted 
for by the fact that great stretches of the country have been 
burnt, and so rendered incapable of growing the lichen so dearly 
loved by these animals.” In the fall of 1889 he personally en- 
countered one of the migrations. ‘‘ With the increasing depth of 
the snow there was a noticeable migration of life, from the 
Barren Grounds. Ptarmigan came literally in thousands, while the 
tracks of wolves, wolverines and Arctic foxes made a continuous 
network in the snow. Scattered bands of caribou were almost 
always in sight from the top of the ridge behind the camp and 
increased in numbers till the morning of October 20th, when we 
were awakened before daylight by the cry of ‘‘La foule,” ‘‘La 
foule,”’ and ever in the lodge we could hear the curious clatter 
made by a band of travelling caribou. La Foule had really come 
and during its passage of six days I was able to realize what 
an extraordinary number of these animals still roam in the Barren 
Grounds. From the ridge we had a splendid view of the migra- 
tion; all the south side of Mackay Lake was alive with moving 
beasts, while the ice seemed to be dotted all over with black 
islands, and still away on the north shore, with the aid of the 
glasses, we could see them coming like regiments on the march. 
In every direction we could hear the grunting noise that the 
caribou always make when travelling; the snow was broken into 
broad roads and I found it useless to try to estimate the num- 
ber that passed within a few miles of our encampment. 
This passage of the caribou is the most remarkable thing that | 
have ever seen in the course of many expeditions among the 
big game of America. The buffalo were for the most part killed 
out before my time, but I cannot believe that the herds on the 
prairie ever surpassed in size La Foule of the caribou.”’
