In a state of nature, the beast is accustomed to wander over large tracts especially favoured by sun and light; even the water he swims in is warmed by the sun. In the gardens in which you strive to rear these beasts, they are kept in dark miserable places, where the water is cold, and which the sun rarely penetrates. You are not kind to them yourselves, and, besides, you allow visitors to tease them.
These errors alone are sufficient to prevent the mother bringing forth a calf that will thrive.
In your cold and variable climates you would do well to have an enclosed place, a kind of conservatory covered over with glass, arranged so as to be opened in warm weather, particularly when the sun shines, and closed during the greater part of the winter, at which time the water, in which the beasts swim, should be warmed by a genial heat diffused through the building. This plan would be much more profitable than your actual dear economy.
If from any cause it is found judicious to separate the mother and the young one, care should be taken to effect the separation immediately after the birth, before the natural food has been tasted, or at least before it has become familiar to the young one, and the calf should be placed where it cannot hear the mother's moaning call.
Warmed sand and moss should be in readiness, in which to immerse and all but cover the little one.
Goat's milk, or other substitutes for the mother's milk, must be administered whilst quite warm and just drawn from the goat. If allowed to stand, the liquid would injure instead of doing good, and even if artificially warmed would not be so beneficial as the new milk.
It is not improbable that the calf will at first refuse the proffered beverage. The expedients for causing the animal to drink should be devised so as to avoid all unnecessary annoyance, and if this precaution be attended to the animal will of its own accord soon drink the warm milk, and take other proper food.
The room where the young one is kept should be of an equal warmth both day and night. In a state of nature the mother obtains this equalization of the temperature, and protects the young one from the comparative chilliness of the night air by lying across the sand in which she has placed the object of her care.
The removal of the young one from the mother is effected with ease; and as this process is with you accompanied by many inconveniences, besides being very difficult and dangerous, a few hints as to our mode of proceeding may be of use.
We have four very long sockets peculiarly formed at their base, so that they can be thrust for a long distance into the sandy ground, and there take the firmest hold. They are placed at certain distances about the spot where the mother lies, and into them are inserted four poles of great strength, so arranged that they stand at the angles of a square or parallelogram, sustaining a framework surmounted by planks sufficiently strong to support four men in case of need, though sometimes two only are required. The men, who are very skilful, are stationed one on each side of the plank, armed with a large strong net, made of a soft and agreeable material, which, as soon as the young one is born, they let down very gradually, so as to disturb the mother as little as possible. Should she be annoyed at the appearance of the net, they hold their hands, keeping it suspended, and as soon as she is appeased and closes her eyes, let it down again, still very slowly, almost imperceptibly, until it has reached the ground, close to where the young one is lying, so contriving that when the little creature moves it will be upon the net.
