"They are a fine, earnest, intelligent, and public-spirited body of men, these rangers. Though small in number, their influence is large. Many and long are the duties heaped upon their shoulders. If a trail is to be blazed, it is "send a ranger". If an animal is floundering in the snow, a ranger is sent to pull him out; if a bear is in the hotel, if a fire threatens a forest, if someone is to be saved, it is " send a ranger." If a dude wants to know why, if a sagebrusher is puzzled about a road, it is "ask the ranger." Everything the ranger knows, he will tell you, except about himself."
- Stephen Mather (first director of the NPS)
