As we go north into British Columbia, through the headwaters of the Peace and Liard rivers, the animal becomes very large in size, perhaps larger than anywhere else in the world as far as his body is concerned, and it is highly probable that somewhere in this neighborhood the range of the giant Alaska moose begins. The species, however, does not show great antler development in this locality, but for some reason the antlers achieve their maximum development in the Kenai Peninsula. In the Kenai Peninsula and the country around Cook Inlet, Alaska, with an unknown distribution to south and east, we find the distinct species recently described as _Alces gigas_. The animal itself has great bulk, but perhaps not more so than the animals of the Cassiar Mountains, to which it is closely related. The antlers of these Alaska moose are simply huge, running, on the average, very much larger and more complex than even picked heads from the east. These antlers, in addition to their size, have a certain peculiarity in the position of the brow antlers, the plane of which is more often turned nearly at right angles to the plane of the palmation of the main beam than in the eastern moose. In a high percentage of the larger heads there is on one or both antlers an additional and secondary palmation. In the arrangement and development of the brow antlers, and in the complexity produced by this doubling of the beam, a startling resemblance is shown to the extinct _Cervalces_, a moose-like deer of the American Pleistocene, possibly ancestral to the genus _Alces_. If this resemblance indicates any close relationship, we have in the Alaska moose a survivor of the archaic type from which the true moose and Scandinavian elk have somewhat degenerated. The photographs of the Alaska moose shown herewith have this double palmation. [Illustration: PROBABLY LARGEST KNOWN ALASKA MOOSE HEAD--KENAI PENINSULA, 1899 EXTREME SPREAD, 78-1/2 INCHES--WEIGHT OF SKULL AND ANTLERS, 93 LBS] Several heads from the Kenai Peninsula ranging over six feet are authentic; a photograph of the largest moose head in the world is published herewith. This head is in the possession of the Field Columbian Museum at Chicago, and measures 78-1/2 inches spread. The animal that bore it stood about seven feet at shoulders, but this height is not infrequently equaled by eastern moose. The weight of the dried skull and antlers was ninety-three pounds, the palmation being in places 2-1/8 inches thick.
