St. Johns kicked the foremost murderer in the stomach, and as the man fell, sprang for a rifle which he kept in the room. The other two attacked him with their axes. He parried one blow, aimed at his head, and the blade buried itself in its hip. While the man was tugging to free the weapon St. Johns felled him with a blow on the jaw. The third Mexican struck downward at almost the same instant, severing St. Johns' left arm near the shoulder. Then the white man got his right hand on his rifle and the three murderers fled. They had killed one of the Americans who was sleeping in the enclosure, left another dying near him and the third gasping his last outside the gate. St. Johns staunched the blood from his wounds and crawled to the top of a pile of grain-sacks whence he could see over the unroofed wall. Here he stayed for three days and three nights. With every sunrise the magpies and buzzards came in great flocks, to sit upon the wall after they had sated themselves in the corral, and watch him. With every nightfall the wolves slunk down from the mountains and fought over the body outside the gate. Night and day the thirst-tortured mules kept up a pandemonium. A road-grading party came along on Sunday morning. They gave him such first aid as they could and sent a rider to Fort Buchanan for a surgeon. The doctor amputated the arm nine days after the wound had been inflicted. Three weeks later St. Johns was able to ride a horse to Tucson. Silas St. Johns is offered as a sample of the men who built and operated the overland mail lines. Among the drivers, stock-tenders, and messengers there were many others like him. Iron men, it was not easy to kill them, and so long as there was breath in their bodies they kept on fighting. John Butterfield and his associates were made of the same stuff as these employees. How many hundred thousand dollars these pioneer investors put into their line before the turning of a single wheel is not known; it must have been somewhere near a cool million, and this was in a day when millions were not so common as they are now; a day, moreover, when nothing in the business was certain and everything remained to be proved.
