The animals in the wilderness are not ferocious, and they wisely flee from the coming of Christian people. Extraordinary skill is required to get close to any wild animal. Even the camera will put the biggest wild folk to flight! They attack only in self-defense, only when cornered and assailed by the hunter. The animals that have survived and left descendants are those which used their wits for flight and not in ferocity. The grizzly constantly uses his wits to keep out of a locality where human beings are. Wolves may once have been ferocious, but at present the aggressive ones are those in the jungles of nature-faking; wolves keep apart from civilization, and travelers are not likely to go out of their way to find them. In story-books the mountain lion crouches upon the cliff or lies in wait upon a tree-limb to spring upon human prey; but real lions do not do this sort of thing. Each year thousands of people scale peaks in the Rockies, the Sierra, and the Selkirks, or spend a less strenuous vacation in the heights, up several thousand feet above the sea. From anæmics who stay at home they hear the common superstition that altitude is harmful! But the travelers return to their homes in high hopes and in vigorous health. The heights are helpful, and the outdoors is friendly at all times. These are splendid sources of hopefulness. They "knit up the raveled sleave of care." They arouse new interests, give broader outlooks. They are great blessings that every one needs. There is a growing appreciation of the safe and sane outdoors. People are rapidly realizing that vacations in the Parks and wild places are needful first aids to impaired health, and also that outdoor life is absolutely necessary for sustained or increased efficiency. From the wilderness the traveler returns a man, almost a superman. Its elemental songs, pictures, and stories are a language of eloquent uplift. Go to the wilderness and get its good tidings! The wilderness is democratic and is full of ideas. It gives efficiency and sympathy. The mingling of all classes in the Parks is a veritable blessing; it is one of the greatest means of preventing internal strife and also of averting international war.
