Gray-wolf 763 



Of the above-mentioned brood of 8 young Wolves in the 

 London Zoo, 4 were raised by a coUie foster-mother, and they 

 became very tame as well as unusually fine specimens. The 

 rest were left with the mother; 2 died. The others grew up, 

 but were weaklings and very shy and wild. The collie was fed 

 on dog-biscuit, the mother Wolf on raw meat, the only food she 

 would touch. 



"After the collie-raised 4 were put in a paddock by them- 

 selves they also grew wild and timid, except i, which for some 

 unknown cause remained tractable and dog-like. This is a 

 most interesting case of individual variation in temperament 

 and suggests how breeds of domestic dogs have been brought 

 to their present condition of tameness by breeding from stock 

 artificially selected for that attribute." {R. I. Pocock in 

 letter.) 



"One was sold to a member of the Society, who lives in 

 the country, where the young Wolf has all the liberty of a dog. 

 It follows a carriage, attends garden parties, and is a favourite 

 with children. It is larger than either of its parents." {Dr. 

 y. D. Drewitt in letter.) 



The following year Dr. Drewitt wrote me, June 25, 

 1905: "Blanca has had another litter of puppies, and, as 

 usual, those that were brought up by a collie wet-nurse were 

 tame, and those which were nursed by the mother, wild. All 

 the puppies had lead-coloured iris. 



Miles Spencer says'^ that the young are suckled for two 

 months after birth, in the region about Hudson Bay. 



Carson, however, writes me: "It is probable they would 

 nurse for five or six months, but as a rule we took them from 

 the mother before they were entirely weaned. The weaning 

 was very gradual, and towards the last the mother would snap 

 when they attempted to suckle her." 



At this time the only enemies that the young Wolves have enemies 

 to fear are eagles, man, insects, and disease. Eagles very often 

 pick up the youngsters, as they play around the den door; man
