bit Baldy, and then, her head being free, turned upon me. Fortunately, Tony caught her free paw on that side, while I jammed the gun-butt into her jaws with my left hand and struck home with the right, the knife driving straight to the heart. The deep fang marks she left in the stock, biting the corner of the shoulder clean off, gave an idea of the power of her jaws. If it had been the very big male cougar which I afterward killed, the stock would doubtless have been bitten completely in two. The dogs were pretty well damaged, and all retired and lay down under the trees, where they licked their wounds, and went to sleep; growling savagely at one another when they waked, but greeting us with demonstrative affection, and trotting eagerly out to share our lunch as soon as we began to eat it. Unaided, they would ultimately have killed the cougar, but the chance of one or two of them being killed or crippled was too great for us to allow this to be done; and in the mix-up of the struggle it was not possible to end it with the rifle. The writhing, yelling tangle offered too shifting a mark; one would have been as apt to hit a dog as the cougar. Goff told me that the pack had often killed cougars unassisted; but in the performance of such feats the best dogs were frequently killed, and this was not a risk to be taken lightly. In some books the writers speak as if the male and female cougar live together and jointly seek food for the young. We never found a male cougar anywhere near either a female with young or a pregnant female. According to my observation the male only remains with the female for a short time, during the mating season, at which period he travels great distances in search of his temporary mates—for the females far outnumber the males. The cougar is normally a very solitary beast. The young—two to four in number, though more than one or two rarely grow up—follow the mother until over half grown. The mother lives entirely alone with the kittens while they are small. As the males fight so fiercely among themselves, it may be that the old he-cougars kill the young of their own sex; a ranchman whom I knew once found the body of a young male cougar which had evidently been killed by an old one; but I cannot say whether or not this was an exceptional case.
