The Kid was now old enough to be dangerous, and his life had been one of irresponsibility and lawlessness. He was nearly at his physical growth at this time, possibly five feet seven and a half inches in height, and weighing a hundred and thirty-five pounds. He was always slight and lean, a hard rider all his life, and never old enough to begin to take on flesh. His hair was light or light brown, and his eyes blue or blue-gray, with curious red hazel spots in them. His face was rather long, his chin narrow but long, and his front teeth were a trifle prominent. He was always a pleasant mannered youth, hopeful and buoyant, never glum or grim, and he nearly always smiled when talking. The Southwestern border at this time offered but few opportunities for making an honest living. There were the mines and there were the cow ranches. It was natural that the half-wild life of the cow punchers would sooner or later appeal to the Kid. He and Jesse Evans met somewhere along the lower border a party of punchers, among whom were Billy Morton and Frank Baker, as well as James McDaniels; the last named being the man who gave Billy his name of "The Kid," which hung to him all his life. The Kid arrived in the Seven Rivers country on foot. In his course east over the mountains from Mesilla to the Pecos valley he had been mixed up with a companion, Tom O'Keefe, in a fight with some more Apaches, of whom the Kid is reported to have killed one or more. There is no doubt that the Guadalupe mountains, which he crossed, were at that time a dangerous Indian country. That the Kid worked for a time for John Chisum, on his ranch near Roswell, is well known, as is the fact that he cherished a grudge against Chisum for years, and was more than once upon the point of killing him for a real or fancied grievance. He left Chisum and took service with J. H. Tunstall on his Feliz ranch late in the winter of 1877, animated by what reason we may not know. In doing this, he may have acted from pique or spite or hatred. There was some quarrel between him and his late associates. Tunstall was killed by the Murphy faction on February 18, 1878. From that time, the path of the Kid is very plain and his acts well known and authenticated. He had by this time killed several men, certainly at least two white men; and how many Mexicans and Indians he had killed by fair means or foul will never be really known. His reputation as a gun fighter was well established.
