The man who addressed them looked no older than themselves, but he was more than twenty years of age. His face was smooth shaven, his complexion clear and his eyes bright. His weight could not have been much above a hundred pounds, and a glance revealed his perfect horsemanship. Alden noted the mail pouches strapped one in front of his knees and the other behind him, and each secured by a lock. He carried a rifle in his left hand and a revolver showed at his hip. He was a fine specimen of the superb Express Rider, temperate, brave, alert, and with extraordinary powers of endurance.
