[AS.] A family of ruminating animals, with slender limbs, and large antlers or horns on the head of the male animal. These are solid, and are shed annually in the spring; but new ones grow rapidly and send out branches, so that in a few months the deer has another pair of horns, each year's antlers increasing in size till the seventh year, after which they get smaller. The deer feed on vegetable substances, and they are wont to swallow large quantities without much chewing, and masticate at their leisure; this they can do because they have a complicated stomach divided into four chambers. (See Digestion.) The reindeer is found in the north of Europe and America. It is used for drawing sleds ; and its flesh and milk supply the natives with food, and its skin with covering. It eats moss and lichen. The horns of the wapiti, or Canadian red deer, weigh more than 60 pounds. The moose, or elk, is the giant of the Deer tribe. The fallow deer has palmated horns. The musk deer is about 20 inches in height. The musk, from which it is named, is secreted in the abdomen.-Deer-stalking, hunting the stag by stealing on it unawares.
