Wild Beasts and Their Ways, Reminiscences of Europe, Asia, Africa and America — Volume 1

by Sir Samuel White Baker

On the following day I managed to get through the pass, and to my intense disgust, upon arrival, I found that I was a day too late, as the Maire, who was a great chasseur, had killed two bears, a mother and half-grown young one, on the preceding day, thus verifying the information I had received.

I saw the freshly killed skins pegged out to dry, and a few days later I ate a portion of the paws in an excellent stew when dining with the Prefect of Bagneres-de-Bigorre, to whom they were forwarded as an esteemed present.

The larger bear-skin gave me the impression that the original owner must have been the size of a heifer twelve or fifteen months old. This was the ordinary brown bear of Europe, which still exists in Transylvania, Hungary, Italy, and especially in Turkey. The same bear inhabits Asia Minor, and both these varieties hybernate at the commencement of winter. In the extensive forests and mountains about Sabanja, beyond the Gulf of Ismid, I have seen the wild fruit trees severely injured by the brown bears, which ascend in search of cherries, plums, apples, walnuts, and sweet chestnuts. The heavy animal knows full well that the extremity of the boughs will not support its weight, it therefore stands erect upon a strong limb and tears down the smaller fruit-laden branches within its reach. Although bears are numerous throughout the forests, there is only one season when they can be successfully hunted; this is in late autumn, when the fruits are closing their maturity, and the apples and nuts are falling to the ground. The bears then descend from the mountain heights, and may be found late in the evening or before sunrise in the neighbourhood of such food.

Asia Minor and Syria possess two distinct varieties of bears, although the countries are closely connected, and these animals are not inhabitants of the same district. The Syrian bear is smaller than the ordinary brown bear, and would hardly exceed 300 lbs. in weight. The fur is a mixed and disagreeable colour, a dusky gray of somewhat rusty appearance, but blanched in portions as though by age. This species is to be found at the present day upon Mount Horeb, and the natives assured me that, when the grapes are ripe, it is necessary to protect them by watchers armed with guns, to scare the bears during night.

Wild animals which hybernate have a peculiar instinct for selecting hiding-places, which can seldom be discovered; in these they lie, free from all intrusion.

The fruits of late autumn fatten the bear to a maximum condition, and when the harvest is over, and the ground is covered with a dense sheet of snow, it retires to some well-known cave, high among the mountains, in such undisturbed seclusion that it is seldom visited by the foot of man. Within a cave, nestled in ferns or withered leaves and grass, the fatted bruin curls itself to sleep throughout the winter months, and the warmth necessary to its existence is supplied by its own fat, which, being rich in carbon, supports vitality at the expense of exhaustion of supply.

If the fat bear could see itself previous to hybernation in November, and again be introduced to its own photograph upon awakening from its sleep in March, it would be prepared to swear against its own identity. It arises from its winter's nap in wretched condition, having lived entirely upon capital instead of income. Young shoots, and leaves of spring, wild tubers which it scratches from the ground, detected by its keen sense of smell, together with snails, beetles, worms, and everything that creeps upon the earth, now form the bill of fare, until the summer brings forth the welcome fruits that reproduce the condition which the bear had lost through hybernation.

It is impossible to unravel many of the mysteries of Nature, and the cause which prompts the instinct of a winter's sleep will always remain doubtful. I should myself attribute hybernation to the necessity of repose at a period when food was impossible to procure. The body can exist for an incredible length of time, provided that it is capable of undisturbed rest, which appears in a certain degree to take the place of extraneous nutriment. It is well known that every exertion of the muscles is a loss of power, the force of the body being represented by heat. To lift a weight or to move a limb requires a certain expenditure of heat, which means force; this loss of heat and power is recuperated by food; thus in the absence of provisions for the necessary supply, there would be no loss of heat if there is no exertion. Sleep is the resource, as the body is not only at rest, but the brain is also tranquil; there is accordingly a minimum of exhaustion. Human beings have been known to live without food of any kind (excepting water) for a period of forty days, and have then resumed their ordinary course, simply confining themselves to moderate diet for the first few days after their long abstinence. In a time of starvation in Africa I have frequently composed myself to sleep in the absence of my daily food, and I have awoke without any disagreeable craving for a meal. Continued sleep will to a certain extent render the body independent of other nutriment, and I should imagine that the custom of hybernation has been induced by necessity. At a season when the fruits of the earth are exhausted, the ground frozen to a degree that would render scratching for roots impossible, an animal that was dependent upon such productions for its existence must either starve or sleep. The sleep is in itself a first stage of the process of starvation. The creature that can sleep through an existence of four months without food, and lose the whole of its fat during that interval of inaction, has already lost all that supported life during the period of total abstinence—the fat, or carbon. If it were to begin another turn of sleep in its exhausted state, it would be unable to support its existence.

I therefore regard hybernation as the result of the highest physical condition, the animal being thoroughly fat; the food ceases, and the beast, knowing this fact, lays itself down to sleep, and exists upon its own fat, which gradually disappears during the interval of starvation. The bear wakes up in spring with a ragged ill-conditioned skin, instead of the glossy fur with which it nestled into rest; and it finds its coat a few sizes too large, until an industrious search for food shall have restored its figure to its original rotund proportions.

The proof of this necessity for repose during a period of enforced abstinence will be observed in the independence of tropical bears, which do not hybernate, for the best of all reasons, "that there is no winter," therefore they can procure their usual food throughout every season without difficulty or interruption.
