On the Herbert River the natives find dingo puppies and bring them up with the children. A puppy is usually reared with great care; he is well fed on meat and fruit and often becomes an important member of the family. His keen scent makes him very useful in trailing game, and his fleetness of foot frequently enables him to run it down. His master never strikes him, though he sometimes threatens to do so.

The threats often end in extravagant caresses. And he seems to respond to this kindly treatment, for the dingo is said to be a "one-man" dog, refusing to follow any one but his master. Nevertheless, the call of the wild, especially in the mating season, often proves too strong for him, and he will rejoin the pack never to return to bis human friends.

When we consider, then, the doglike friendliness of which these wild forms are capable, even in the first generation, it is not difficult to believe that they are the ancestors of our domestic dogs, with which they freely interbreed.

Our belief is still further strengthened if we consider how closely many of the domesticated dogs resemble the wild forms of the same regions. The resemblance is nowhere stronger than in the Eskimo dogs of Greenland and Alaska, which are believed to be simply domesticated wolves. Some of the Arctic explorers have called attention to the difficulty of distinguishing them from the wild wolves of the same region.

A ship's mascot is as truly essential in the maintenance of morale among bluejackets as are clean quarters, good food, and strict discipline. These tiny tykes, with their blankets bearing service stripes, are important units of the United States battleship Oklahoma's complement of fighters.

Captain Parry, in the journal of his second voyage, speaks of a pack of 13 wolves which came boldly within a few yards of his ship, The Fury, but which he and his men dared not shoot, because they could not be quite sure that they were not shooting sledge dogs and thus doing the Eskimos an irreparable injury.

A few years ago Admiral Peary kindly conducted me over Flag Island, in Casco Bay, that I might see the pure-bred North Greenland Eskimo dogs which he brought back after his discovery of the North Pole. When these animals carried their tails curled over their backs, as they usually do. there was no mistaking them for anything else but dogs, but the moment they lowered their tails, as they often did, to all appearances they were gray wolves.

Another striking example of this similarity between Eskimo dogs and wolves is shown in a photograph by Donald B.

MacMillan of one of his female Eskimo dogs, standing with lowered tail watching a litter of puppies which she is nursing. The puppies, which are spotted, are evidently not pure breed, but the mother looks as much like a timber wolf as any timber wolf I ever saw.

In the same way some of the dogs which in former years were found among the Indians farther south closely resembled coyotes.

Many of the pariah dogs of India look much like the wolves of that country; in southeastern Europe and the south of Asia many of the breeds of dogs bear a close resemblance to the jackals of the same districts, and some of the South American dogs show a marked similarity to the small South American wolves. It was such considerations which led Darwin to the following conclusion:

"It is highly probable that the domestic dogs of the world are descended from two well-defined species of wolf, namely, Canis lupus and Canis latrans, and from two or three doubtful species, namely, the European, Indian, and North African wolves; from at least one or two South American canine species; from several races or species of jackals, and perhaps from one or more extinct species".
