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. As soon as the young one is fairly on the net, the men apply several long canes furnished with grappling-hooks, and draw up the net containing the young one. While doing this, they throw over the mother a material which impedes her movement, and which we call by a name that may be freely translated, "Clinging Flannel." The animal thus encumbered cannot disentangle herself for a few minutes, more than sufficient to secure the capture of the little one, which, as soon as it has been raised is let down into a vehicle ready to receive it. The instant this is done, the driver and all being in readiness, the horses start off at full gallop, and the calf is secured in a place far out of hearing of the mother.
