Williams was regarded as a warm-hearted, brave, and generous man. He was at last killed by the Indians, while trading with them, but has left his name to many mountain peaks, rivers, and passes discovered by him. Tom Tobin, one of the last of the famous trappers, hunters, and Indian fighters to cross the dark river, flourished in the early days, when the Rocky Mountains were a veritable terra incognita to nearly all excepting the hardy employees of the several fur companies and the limited number of United States troops stationed in their remote wilds. Tom was an Irishman, quick-tempered, and a dead shot with either rifle, revolver, or the formidable bowie-knife. He would fight at the drop of the hat, but no man ever went away from his cabin hungry, if he had a crust to divide; or penniless, if there was anything remaining in his purse. He, like Carson, was rather under the average stature, red-faced, and lacking much of being an Adonis, but whole-souled, and as quick in his movements as an antelope. Tobin played an important role in avenging the death of the Americans killed in the Taos massacre, at the storming of the Indian pueblo, but his greatest achievement was the ending of the noted bandit Espinosa's life, who, at the height of his career of blood, was the terror of the whole mountain region. At the time of the acquisition of New Mexico by the United States, Espinosa, who was a Mexican, owning vast herds of cattle and sheep, resided upon his ancestral hacienda in a sort of barbaric luxury, with a host of semi-serfs, known as Peons, to do his bidding, as did the other "Muy Ricos," the "Dons," so called, of his class of natives. These self-styled aristocrats of the wild country all boasted of their Castilian blue blood, claiming descent from the nobles of Cortez' army, but the fact is, however, with rare exceptions, that their male ancestors, the rank and file of that army, intermarried with the Aztec women, and they were really only a mixture of Indian and Spanish. It so happened that Espinosa met an adventurous American, who, with hundreds of others, had been attached to the "Army of Occupation" in the Mexican War, or had emigrated from the States to seek their fortunes in the newly acquired and much over-rated territory. The Mexican Don and the American became fast friends, the latter making his home with his newly found acquaintance at the beautiful ranch in the mountains, where they played the role of a modern Damon and Pythias. Now with Don Espinosa lived his sister, a dark-eyed, bewitchingly beautiful girl about seventeen years old, with whom the susceptible American fell deeply in love, and his affection was reciprocated by the maiden, with a fervour of which only the women of the race from which she sprang are capable.
