I was very much interested in this animal, and took a great deal of pains to tame her, though I never fully succeeded. Her nose, as I have said, was excellent; and though quite mute she could hunt very well, as I found by repeated trials when out rabbit shooting. She would never leave a hole, working at it with her feet and teeth until she got at the inmate. These qualities confirmed me in my opinion that a cross with the fox-hound would produce a good result. As an illustration of her keenness of smell, I may mention that one day when we were lying in the Tamar river, she winded some sheep on the bank, and was instantly overboard and after them, swimming so rapidly that she had reached the land, and, though herself only the size of a large dog-fox, had pulled down a fine ram before a party could get on shore to prevent her. When they landed, instead of trying to make her escape, she slunk into the boat. This freak of hers cost me five pounds. PECULIARITIES OF THE WILD DOG. In cold weather her coat was always best, and the brush on her tail most perfect. She was of a light tan colour, with a little white on the tip of the tail, and a few black hairs sprinkled in the brush; there was a little black also about her face. Her step was light and stealthy; and in her eye meekness and cunning were curiously blended. Though very shy of man, when once taken up in the arms she lay as quiet as a cat; but with all dogs she was very quarrelsome, fighting savagely with a greyhound bitch I had on board, and several times nearly killing a small dog. It was always difficult to catch her, as she would generally manage to escape either between the legs or by springing over the shoulders, except when we were going on shore; then she would allow herself very quietly to be put into the boat; but on our return the difficulty was how to get her off, and it became necessary to pounce upon her suddenly. She was never heard to bark, the only noise she ever made being the dismal howl peculiar to her breed, and this only when tied up, which consequently, for the sake of peace, was but of short duration, and always had to be done with a chain, as she would instantly bite through a rope. Her mischievous propensity was remarkable, as she often stole into the officers' cabin and pulled books down from the shelves, tearing the backs off and then destroying the leaves. As an instance of her sure-footedness and activity I may mention that I have seen her leap twice her own height from the stem of the midship boat, in endeavouring to seize fowls or meat that was hung on the mainstay, always alighting on the point she sprang from. At other times she would attempt to crawl up it like a cat, in order to steal what was there. Her proneness to thieving was very great; I have frequently seen her eating stolen things when she would refuse what was offered her; it was never safe to take her near poultry.
