The Glutton or Wolverine ( Oulo luscusj is allied to the Bears, Badgers, 
Otters, and Mustelidce. Old authors have told wonderful tales of its 
climbing trees and pouncing upon the backs of Eeindeer and Elks as they 
passed beneath. It is no doubt extremely voracious, but modern travellers 
assert that its attacks upon the larger animals are chiefly made upon them 
during their sleep, or upon weaker dying deer or young fawns. It is 
extremely mischievous, and a great pest to the hunters and trappers of the 
fur countries by destroying their traps for the sake of the bait. Its strength 
is prodigious. It has been known to disarrange piles of wood among which 
were trees that had required two men to lift them. 
The Esquimaux Dog ( Canis familiaris. var. BorealisJ is well known. His 
sagacity in the chase, his patience and perseverance in the sledge-team and 
his great speed, render him an invaluable possession to the native inhabitant 
or the more civilized explorer of the northern regions. Though generally 
treated with harshness by their masters and often half-starved they seldom 
rebel against human authority. They will attack the Bear and every other 
animal except the "Wolf, to which they have a great antipathy. 
The Wolf is one of the tyrants of the northern parts of the world, and is 
found in both hemispheres. Its great strength, rapidity of movement and 
savage disposition render it the terror of all animals inferior to itself in 
these qualities. Its strength and courage even after being wounded are 
the subject of many interesting anecdotes by writers on northern research 
and adventure. 
The resemblance between the Wolf and the Dog has been noticed by 
many writers. Cases are on record in which dogs have themselves mistaken 
wolves for animals of their own species and have fallen victims to the 
delusion. Dr. Kane says " There is so much of identical character between 
our Arctic Dogs and Wolves, that I am inclined to agree with Mr. 
Broderip, who in the ' Zoological Eecreations ' assigns to them a family 
origin. Both animals howl in unison alike. Their footprint is the same, 
at least in Smith's Sound. Dr. Eichardson's remark to the contrary made 
me observe tho fact that our northern dogs leave the same ' spread track ' 
of the toes when running, though not perhaps as well-marked as the 
Wolfs." 
The Arctic Fox (Vulpes lagopus) is found in both hemispheres. It has a 
fine fur, bluish gray in summer and pure white in winter. Its habits are 
gregarious, twenty or thirty burrowing together. It is easily taken in 
traps and tamed without difficulty. It is said that this little animal hunts 
with the Bear, and "It is certain, " says Dr. Kane, " that they are of ten
