[Illustration: “BIERSTADT” HEAD. KILLED 1880, BOUNDARY OF NEW BRUNSWICK AND MAINE EXTREME SPREAD, 64! INCHES]
A similar change takes place in the bell. This pendulous gland is long and narrow in the young hull, but as he ages it shortens and widens, becoming eventually a sort of dewlap under the throat.
One of the best heads from Maine that I can recall, was in the possession of the late Albert Bierstadt, a member of the Boone and Crockett Club. The extreme spread of these antlers was 64-1/4 inches. This bull was killed in New Brunswick, near the Maine line, some twenty years ago; another famous Maine head was presented to President Cleveland during his first term. Photographs of both of these heads appear herewith. Many very handsome heads have been taken in the Ottawa district, sometimes running well over five feet. It is safe to assume that a little short of six feet is the extreme width of an eastern head.
The moose of the Rocky Mountains are relatively smaller than the eastern moose, and their antlers are seldom of imposing proportions.
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.
