The author was determined to practice medicine awhile in some wild place far from cities. He graduated at Bellevue Medical College, New York, interned at Charity Hospital, was a surgeon at the prison on Blackwell's Island and had a six months surgical service in New York Hospital; but such places did not appeal to him. He started for the silver mining region of western Colorado in the heart of the Rocky Mountains with little money or experience, intending to try this sort of living for one year; but he stayed fifty years. His has been the delight of seeing snow covered mountains, breathing pure air, having the sunshine and blue sky and of knowing men in the rough. At first he practiced in the silver camps, high, often above the timberline, with deep snow covering the ground for nine months in the year ; then he moved to the cattle country at a lower altitude around 6,000 feet. Here he practiced medicine among cowboys, Indians, hunters, outlaws, gamblers and fugitives, men rough in speech and action and yet with a fine regard for honor, honesty and truth. The author was 5 feet 7 inches tall and never weighed more than 110 pounds. He writes of narrow escapes from snow slides, of long horseback rides over dangerous mountain trails, of professional contact with lawless characters, of cutting and shooting affairs, of babies born in snow
