THE BIGHORN OF THE ROCKIES 23 wander over to the Purcells, but his residence there is never of long duration, and I have only heard of such a thing happening on one or two occasions. The sheep of the Cascades are also locally called “ Big- horn,” but in my opinion, while they may bear a strong resemblance to those of the Rockies, and may not have sufficiently distinct differences.to warrant them being classed separately, they are of such an inferior type that they are not worthy of the name of “ Bighorn.” Sucha fitting title should be reserved to distinguish the grand monarchs of the Rockies of Canada, who stand in a class by themselves, not only from those of the Cascades, but also from all other brown sheep, whether from Wyoming, California or Mexico, as far as size of horns, weight of body and value as a trophy are concerned. While brown sheep are to be found from north of the North Fork of the Fraser River—their extreme northern limit has not been positively determined—to as far south as Mexico, they reach their highest stage of development in the limestone mountains of that portion of the main range of the Rockies which lies between the United States boundary line and the vicinity of the main line of the Canadian Pacific Railway. The finest trophies ever taken have come from this area, either on this side of the Rockies or that in Alberta. The summit of the range divides the two Provinces, and there you must go if you covet an exceptionally fine head. The sheep range on the British Columbia side of the Rockies is by no means continuous ; in fact, it is only in spots that it is suitable for this animal; much of it is far too broken up and precipitous, and only inhabited by Mountain Goats. This is particularly the case where the main line of the Canadian Pacific Railway cuts the range ; from that point there are no sheep for many miles north and for a short distance south, This statement only applies to this Province, as on the Alberta side of the line the sheep range is less divided up. While the main line of the Canadian Pacific Railway passes through country where there are no sheep, the Crow’s TT
