While I was looking at the magnificent horns of some of the beasts, Pehr remarked: "The horns of the males, which often weigh forty pounds, attain the full size at the age of six or seven years, those of the cow at about four years. The time the reindeer drops his horns is from March until May. In the adult animals they attain their full size in September or at the beginning of October. After the age of eight years the branches gradually drop off. They are the easiest animals that man can keep. They require no barns. They are never housed. They like cold weather and snow. Food has not to be stored for them. They will not touch the moss that has been gathered unless brought up to do so by farmers. They get their food themselves. We do not give them water. When thirsty they eat the snow. When our people go among them they will often not even raise their heads, and remain quiet when we pitch our tents. Once in a while there is so much snow in some districts that it is impossible for reindeer to get at the moss; then the only way is to go to the lowlands, or into the forest, where the reindeer can feed on the moss hanging from the firs or pines. "Some of the reindeer," he went on, "though trained to eat kept moss, hay, and even bread, thrive only when they are free to roam about; they cannot be kept all the time in their stables. They must wander over the snow and eat it. Otherwise they are sure to degenerate and become useless as draught animals." "How many reindeer," I asked, "does a family require for its support?" He replied, "A thousand at least. A herd of two thousand to two thousand five hundred gives from two hundred to two hundred and seventy-five, perhaps three hundred, calves a year. Sometimes we have bad years with our reindeer. Some years prove unfavorable to their increase. Some years the snow is very deep, which prevents them from digging for food; the herd then become emaciated from their exertions and want of sufficient food, and many die. "Some Lapps," he added, "own five or six thousand reindeer, one or two among us, eight or ten thousand. The spring is a bad time for them; the snow melts during the day from the sun's heat, and a thick crust forms at night from the frost, so that their feet break through, causing lameness and disease. At that time we move them as much as we can only during the day, but it is hard work for them to go through the soft snow. "Without the reindeer we could not exist in this northern land of snow. The reindeer is our horse, our beast of burden. On him we feed. He gives us our clothing, our shoes, our gloves; his skin is our blanket and our bed; his sinews our thread. On the march a herd of reindeer is easily managed. We keep them together without much trouble, and in winter they remain where we leave them to get the moss; but if the wolves are after them, then they flee in every direction, and many herds then become mixed together."
