ters of both forms of Dall's sheep are
Messrs. Dali DeWeese, of Colorado, and A.J. Stone, Collector of Arctic
Mammals for the American Museum of Natural History. Mr. Stone gives two
distinct ranges for this sheep, (1) the Alaska Mountains and Kenai
Peninsula, and (2) the entire stretch of the Rocky Mountains north of
latitude 60 degrees to near the Arctic coast just at the McKenzie,
reaching thence west to the headwaters of the Noatak and Kowak rivers
that flow into Kotzebue Sound.

Stone's sheep, which was described by Dr. Allen in 1897, came from the
head of the Stickine River, and two years after its description Dr. J.A.
Allen quotes Mr. A.J. Stone, the collector, as saying: "I traced the
_Ovis stonei_, or black sheep, throughout the mountainous country
of the headwaters of the Stickine, and south to the headwaters of the
Nass, but could find no reliable information of their occurrence further
south in this longitude. They are found throughout the Cassiar
Mountains, which extend north to 61 degrees north latitude and west to
134 degrees west longitude. How much further west they may be found I
have been unable to determine. Nor could I ascertain whether their range
extends from the Cassiar Mountains into the Rocky Mountains to the north
of Francis and Liard River. But the best information obtained led me to
believe that it does not. They are found in the Rocky Mountains to the
south as far as the headwaters of the Nelson and Peace rivers in
latitude 56 degrees, but I proved conclusively that in the main range of
the Rocky Mountains very few of them are found north of the Liard
River. Where this river sweeps south through the Rocky Mountains to
Hell's Gate, a few of these animals are founds as far north as Beaver
River, a tributary of the Liard. None, however, are found north of this,
and I am thoroughly convinced that this is the only place where these
animals may be found north of the Liard River.

"I find that in the Cassiar Mountains and in the Rocky Mountains they
everywhere range above timber line, as they do in the mountains of
Stickine, the Cheonees, and the Etsezas.

"Directly to the north of the Beaver River, and north of the Liard River
below the confluence of the Beaver, we first meet with _Ovis
dalli_."

A Stony Indian once told me that in his country--the main range of the
Rocky Mountains--there were two sorts of sheep, one small, dark in
color, and with slender horns, which are seldom broken, and an
