146 CARIBOU highest state of development, and in every respect exceed any other species of that family. In body growth they almost come up to the wapiti; in fact, some of the bulls put on such an enormous amount of fat that they might easily weigh heavier, even if they are not as tall. Nobody whom I know has ever weighed a full-grown bull caribou, but if bull-moose ever reach a weight of 1,400 lb., which they are said to, and which I very much doubt, some of the Osborn caribou should go 700 Ib. at the very least. All I actually know of their weight is that it is a hard struggle for one man to roll the carcase of a big bull over by himself unless he has a slope to help him. To the north and south of Cassiar the caribou deteriorate; in the first case grading off into the Arctic and in the second into the mountain species. Both species of our caribou migrate more or less, but in no case are the distances travelled in these migrations to be compared with those of their Arctic relatives; nor do they band up into the like huge droves of thousands, but move in small companies of anywhere from ten to forty. Curiously, the mountain caribou of the Selkirks seem to have more regular migrations than the Osborn, and year after year they keep to the same route, crossing valleys, lakes, and rivers at the same places. Nor does the time of these migrations often vary more than a few days, and there are several places where anybody could go to and sit down and be almost sure of seeing a few head within the period of a week, though at other times of the year there would not be one of these beasts within miles of the spot. One of these crossings is situated on the main line of the C.P.R., where you could camp right beside the railway track, and all you would have to do would be to watch one small gravel bar that is not more than seventy-five yards long. Usually when they come to this bar, whether singly or in twos or threes, they linger about on it for a time, perhaps only for half an hour or perhaps for half a day, The engineers on the trains often see them at this place. Luckily such crossings are only known to the favoured few, who keep the know-
