The Indians rode round the upper side of Sidney--_i.e._ west--after the affray with the conductors, and attacked the section-men, circling round and round (as usual in their mode of Indian warfare, to draw out the fire of their enemies, till they exhaust their ammunition), till they had killed several of the poor Irishmen at work. These men had with them a hand-car, and the boss had a rifle with him, and only one charge or cartridge in his gun. He did the best he could, however, by jumping on the car and taking aim at his enemies, and keeping the gun pointed towards them, while the men worked the hand-car safe into Sidney Station. He escaped with his life, and several of his comrades. These two conductors had about seven arrows shot into each of them, several going right through their bodies, and which had to be broken off to draw them out. One--Thomas Cahoone--was scalped twice, on the top and back of his head. The other--William Kinney--kept his captor at bay by a pistol he had, and thus aiming at the Indian, saved his hair. Both were brought up carefully in the caboose-car to Cheyenne, and next day I saw them under Dr. Latham's treatment. All thought that both would surely die, but both got well; and the one who was scalped is now living at a station on the Union Pacific Railroad. It is a terrible operation to be scalped, and few survive it. But, thanks to the surgeon's skill, these men are living, and feel very much like taking vengeance on their tormentors,--_if they ever catch them_! WHY DO INDIANS SCALP THEIR ENEMIES?
