There are both wild and tame rein-deer in Lapland. In the rutting season the females are let loose to seek the wild males in the woods; and as these wild males are more robust, and stronger than the domestic ones, the breed from this mixture are preferred for harness. These rein-deer are not so gentle as the others, for they not only sometimes refuse to obey those who guide them, but often turn and furiously attack them with their feet, so that they have no other resource than to cover themselves with the sledge until the fury of the beast is subsided. This sledge is so light that the Laplander can with ease turn it over himself; the bottom of it is covered with the skins of young rein-deers, the hair of which is turned backwards, so that the sledge glides easily forwards, and is prevented from recoiling on the mountains. The harness of the rein-deer is only a collar made of the skin, with the hairs remaining on it, from whence a trace is brought under the belly, between the legs, and fastened to the fore part of the sledge. The Laplander has only a single cord, as a rein, fastened to the animal's horn, which he throws sometimes on one side and sometimes on the other of the beast, according as he would direct him to the right or left. They can travel four or five leagues an hour; but the quicker he goes the more inconvenient is the motion, and a person must be well accustomed, and travel often, to be able to sit in the sledge, and prevent it from turning over. The rein-deer have outwardly many things in common with the stag, and the formation of their interior parts is nearly the same. From this conformity of Nature, analogous customs and similar effects result. The rein-deer sheds his horns every year like the stag, and, like him, makes very good venison. The rutting season of both is towards the end of September. The females of both species go eight months with young, and produce but one at a birth. The males have the same disgustful smell in their rutting time; and among the female rein-deer there are also found some who are barren. The young rein-deer, like the young fawns of the stag, are variously coloured; it is at first of a reddish colour, and becomes, as they grow old, almost of an entire brown. The young follow their mothers two or three years, and they do not attain their full growth till the age of four; it is at this age that they begin to dress and exercise them for labour. In order to render them more manageable they are castrated when young, which operation the Laplanders perform with their teeth. The uncastrated males are very difficult to manage, and they therefore make use only of those which are gelded, among which they choose the most lively and nimble to draw their sledges, and the more heavy to carry their provisions and baggage. They keep only one stallion rein-deer for five or six females. These animals are troubled with an insect, called the gad-fly, who
