. Annual report of the New York State College of Agriculture at Cornell University and the Agricultural Experiment Station. New York State College of Agriculture; Cornell University. Agricultural Experiment Station; Agriculture -- New York (State). 1212 Home Nature-Study Give us a chance and we will keep clean Facts for Teachers.—That the hog has become synonymous with filth is the result of the influence of man upon this animal, for of all animals the pig is naturally the neatest, always keeping !ts bed clean and often in the most discouraging circumstances of ill-kept pens. The pig is sparsely clothed with bristles and hairs, which yield it no protection from the attacks of flies and other insects. Thus it is that the pig in order to rid itself of these pests has learned to wallow in the mud. And as the pig does not perspire freely the mud baths seem to keep the body cool during the hot weather. The wild hogs of India make for them- selves grass huts thatched above and with doors at the sides, which shows that the pig, if allowed to care for itself, understands well the art of nest building. One of the most interesting things about a pig is its nose. This is a fleshy disc with nostrils in it and is a most sensitive organ of feeling; it can select grain from chaff, and yet is so strong that it can root up the ground in search for food. The expressive word " root " was evidently coined to describe the act of the pig when digging for roots. The pig's nose is almost as remarkable as the elephant's trunk; the pig's sense of smell is very keen, and it will follow a track almost as well as will a dog. More than once has a pig been trained as a pointer in hunt- ing birds, a fact which shows the keener sense of smell and keener intelligence in this capacity than in dogs. French pigs are taught to hunt for truffles, fungi that grow on tree roots a long way below the surface of the ground. The pig's sense of smell is keen enough to detect their presence.
