THE AMERICAN REINDEER. 133 



America is fiir Icsh nntjjratory in its hal)it8 than the larger 

 species, and with the mnsk-sheep (()vil)os) ri'inains in the 

 same localities throughout the year. 



In forest districts, in many parts of its range over the 

 1 Northern American continent, the cari])oo is found to- 



gether with the moose in the same woodlands. They 

 a[»pear, however, to avoid each other's com]);tny; and I 

 luive observed in following the tracks of a travellino- band 

 of cariboo, that, on passing a fresh moose-yard, they have 

 broken into a tr(jt — a sure sign of alarm. In many 

 districts, especially those in which the existing southern 

 limits of the caril)00 are marked, this animal is gradually 

 disappeai'ing, whilst the moose is taking its place. To a 

 great extent this is the result of an inci-easing settlement 

 of the country by man. The moose is a much more i 



domestic anim;d in its habits, and will remain and '■• 



multipl}' in any small forest district, however the latter * 



may be surj-ounded by roads or settlements ; whereas the ;' 



caril)oo is a great Avanderer, and recjuires long and i 



unbroken ranges of wild country in which he can r 



uninterruptedly indulge his vagrant habits. Being more- ', 



over more jeahjus of the advance of civilisation than the I' 



moose, he is surely disappearing as his old lines of i* 



periodic migration are encroached upon and broken by j\ 



new settlements and their connectinr^ roads. i 



In winters of great severity the cariboo always travel 

 to the soutliernmost limits of their haunts, which i.- 



thev occasionallv exceed and enter the settlements. '■• 



Some years aw, durini'' an unusuallv cold winter, the ;• 



deer crossed in large bands from Labrador into New- 

 foundland over the frozen straits. As assumed by Dr. j- 



Gray, a variety appears to be established in the case of 1^
