That dogs sometimes make mistakes in the exercise of their intelligence, with somewhat ludicrous results, is of course true. A dog once accompanied a gentleman's servant to a tailor's with a coat of his master's which needed repair. Having his suspicions with regard to the transaction, the dog watched his opportunity, seized the coat from the counter and carried it back with evident satisfaction to his master. Another dog caused great amusement at a swimming match by insisting upon the rescue of one of the competitors. Dogs have also been known to cause both amusement and consternation by leaping upon the stage to rescue the defenceless characters of the melodrama from the hands of the heavy villain of the play. The story of the dog who failed to recognise his master who had been bathing, and who therefore refused to allow him to have his clothes, is probably apochryphal, but if true is another illustration of the awkwardness of dogs' mistakes.
Colonel Hamilton Smith in his classification of dogs begins with those which belong nearest to the arctic circle, and it will be convenient to follow his order in so far as space will allow. Speaking of the Eskimo dog Captain Lyon says:--"Having myself possessed during our hard winter a team of eleven fine dogs, I was enabled to become better acquainted with their good qualities than could possibly have been the case by the casual visits of the Esquimaux to the ships. The form of the Esquimaux dog is very similar to that of our shepherd's dog in England, but it is more muscular and broad-chested, owing to the constant and severe work to which he is brought up. His ears are pointed, and the aspect of the head is somewhat savage. In size a fine dog about the height of the Newfoundland breed, but broad like a mastiff in every part except the nose. The hair of the coat is in summer, as well as in winter, very long, but during the cold season a soft, downy under-covering is found, which does not appear in warm weather. Young dogs are put into harness as soon as they can walk, and being tied up, soon acquire a habit of pulling, in their attempts to recover their liberty, or to roam in quest of their mother. When about two months old, they are put into the sledge with the grown dogs, and sometimes eight or ten little ones are under the charge of some steady old animal, where, with frequent and sometimes severe beatings, they soon receive a competent education. Every dog is distinguished by a particular name, and the angry repetition of it has an effect as instantaneous as an application of the whip, which instrument is of an immense length, having a lash from eighteen to twenty-four feet, while the handle is one foot only; with this, by throwing it on one side or the other of the leader, and repeating certain words, the animals are guided or stopped. When the sledge is stopped they are all taught to lie down, by throwing the whip gently over their backs, and they will remain in this position even for hours, until their master returns to them. A walrus is frequently drawn along by three or four of these dogs, and seals are sometimes carried home in the same manner, though I have in some instances seen a dog bring home the greater part of a seal in panniers placed across his back. Cold has very little effect on them; for although the dogs at the huts slept within the snow passages, mine at the ships had no shelter, but lay alongside, with the thermometer at 42° and 44°, and with as little concern as if the weather had been mild. I found, by several experiments, that three of my dogs could draw me on a sledge, weighing one hundred pounds, at the rate of one mile in six minutes; and as a proof of the strength of a well-grown dog, my leader drew one hundred and ninety-six pounds singly, and to the same distance, in eight minutes. At another time seven of my dogs ran a mile in four minutes, drawing a heavy sledge full of men. Afterwards, in carrying stores to the Fury, one mile distant, nine dogs drew one thousand six hundred and eleven pounds in the space of nine minutes. When the dogs slackened their pace, the sight of a seal or bird was sufficient to put them instantly to their full speed; and even though none of these might be seen on the ice, the cry of 'a seal!'--'a bear!'--or 'a bird!' &c., was enough to give play to the legs and voices of the whole pack. The voice and long whip answer all the purposes of reins, and the dogs can be made to turn a corner as dexterously as horses, though not in such an orderly manner, since they are constantly fighting; and I do not recollect to have seen one receive a flogging without instantly wreaking his passion on the ears of his neighbours.
