They may do this for better food opportunities and increased safety from enemies, but it is also plain that many birds come chiefly to satisfy their desire for human society. It has been often demonstrated that shy, well-fed birds and animals are hoping and waiting for friendly advances on our part. Wild neighbors are glad of the opportunity to call on us, whether we break bread or not. They are also glad to have friendly calls returned. Birds and animals have individuality. Food and kindness, and speaking to animals in the universal language--friendly tones--are all means of promoting acquaintance. In the past we have greatly underrated the mental powers of animals. An intimate association with wild life in the Parks will probably convince most people that wild animals have the power to think and reason. It may also acquaint people with the fact that animals as well as human beings possess the traits of love, hatred, jealousy, anger, and revenge. Any one who associates much with wild life will discover the exceptional keenness of animal senses. In most animals scent is amazingly developed, and probably is the first of the senses to warn them of danger. Most animals may be spoiled by excessive or improper feeding. In the Yellowstone Park the bears, which are omnivorous feeders, have free access to the garbage-dumps and eat all sorts of unwholesome abominations. This improper eating is bound to have a bad influence upon their habits, and is already spoiling their disposition. Beasts of prey in the Parks are held in check by the Government. Lions, lynxes, and other animals that become numerous and destructive, or bears that develop killing habits, are disposed of by the Government. The excess of big game and birds in the Parks overflows and stocks the territory outside. Each year, too, hundreds of elk and other big animals are shipped from Yellowstone to many parts of the country. Well might these Parks supply city zoos, or, better still, big wild-life reservations, with all available kinds of animals needed. As well ship deer, moose, bears, beavers, and antelopes as to ship elk. Here is a large field for the distribution of wild life all over the United States. The general restocking of state and government wild-life reservations may enable cities to cease maintaining their animal prisons--the zoos. XVIII IN ALL WEATHERS
