The younger man saw that the engagement at this end of the line was no longer general, but had become a series of individual combats, so he made what haste he could toward the scene of the more serious encounter to the right of the crossing. He judged that the issue was still in doubt there, although he could make out little in the confusion on account of the glaring headlight, which dazzled him. As he ran, however, he discovered that the S. R. & N. forces were in possession of the middle ground, having divided the enemy's ranks like a wedge, and this encouraged him. Out of the darkness to right and left came shouts, curses, the sounds of men wallowing about in the knee-deep tundra. They were Gordon's helpers who had been routed from their positions. Now that Appleton had time to collect himself he, too, grew sick with suspense, for he knew that arms had been stacked inside the barricades. Any instant might bring them into play. He began to wonder why Denny withheld the word to fire. As a matter of fact, the explanation was simple, although it did not appear until later. Mr. Denny at that moment was in no condition to issue orders of any kind, the reason being as follows: when preparations for the advance were made, Dr. Gray, who understood perhaps more fully than any one else except O'Neil the gravity of the issue and the slender pivot upon which the outcome balanced, had taken his place in the vanguard of the attacking party instead of in the background, as befitted his calling. The first rush had carried him well into the fray, but once there he had shown his good judgment by refusing to participate in it. Instead, he had selected Denny out of the opposing ranks and bored through the crowd in his direction, heedless of all efforts to stop him. His great strength had enabled him to gain ground; he had hurled his assailants aside, upsetting them, bursting through the press as a football-player penetrates a line; and when the retreat had begun he was close at the heels of his victim. He had overtaken Denny beside one of the barricades just as Denny seized a rifle and raised it. With one wrench he possessed himself of the weapon, and the next instant he had bent the barrel over its owner's head. Then, as the fight surged onward, he had gathered the limp figure in his arms and borne it into the light of a gasolene-torch, where he could administer first aid. He was kneeling over the fellow when Appleton found him as he came stumbling along the grade.
