Both males and females are capable of generating when two years old. It is probable that the female may be more forward than the male; it is, however, certain, that they are not inclined to copulate before the second winter, which necessarily implies 18 or 20 months of age; a she-wolf, which I reared, discovered no symptoms until the third winter, when she was more than two years and a half old. Huntsmen assert that in every litter there are more males than females, which seems to confirm the general remark, that Nature, in all species, produces more of the former than the latter. From them also we learn that some of the males attach themselves to the females, and accompany them until they are about to bring forth, when she steals from him, and carefully hides her young, lest he should devour them immediately after birth; but that when brought forth, he takes the same care of them as the female, carries them provisions, and if the mother happens to be killed, he carefully brings them up. I cannot, however, pretend to vouch for the truth of these facts, which appear to me contrary to their natural dispositions. These animals require two or three years to complete their growth, and live to the age of 15 or 20; another proof of our position that the growth takes up one seventh part of life. As the wolf grows old he turns grey, and his teeth appear much worn. He sleeps when full or fatigued, but more by day than night, and is always very easily awakened. He drinks frequently, and in times of drought, when there is no water in holes or trunks of trees, he will come to the brooks or rivulets several times in the day. Although very voracious, he will go four or five days without meat, provided he is well supplied with water. He has great strength, particularly in his fore parts, in the muscles of his neck and jaws. He will carry off a sheep in his mouth, without letting it touch the ground, and at the same time outrun the shepherds, so that nothing but dogs can overtake or oblige him to quit his prey. He bites cruelly, and always with greater vehemence in proportion as he is less resisted, for with such as can defend themselves he is cautious and circumspect. He is cowardly, and never fights but from necessity. When wounded by a bullet he will cry out, and yet when surrounded and dispatched by clubs, he never complains like the dog, but defends himself in silence, and dies as hard as he lived. He is more savage, has less sensibility, and more strength than the dog. He travels and roams about for nights and days together, and perhaps of all animals is the most difficult to be hunted down. The dog is gentle and courageous; the wolf though savage is fearful. If entrapped in a snare he is for some time so frightened and overcome, that he may be killed or taken alive, without offering to resist; he will suffer himself to be chained, muzzled, and led along without giving the least signs of anger or resentment. His senses, particularly
