The light of the fired train had hardly flashed before the first sentry who saw it, fired, to be followed by one after another, till the bugles rang out, first one and then another, whose notes were still ringing when there was a muffled roar, then another, and another, till six had shaken the earth and a series of peculiar metallic clashes deafened all around. But before the first sentry had raised his piece to his shoulder and drawn, the sergeant, seen in the brilliant light of the running train, seemed to have gone frantically mad. "Chuck, sir, chuck!" he yelled, though Lennox needed no telling. The light which suddenly shone on the back of the cluster of sheet-iron huts had shown him what was necessary, and after raising the bag he had picked up with both hands high above his head, and hurling it as far as he could, he dashed at the others he could see packed close up against the colonel's hut, so that between him and the sergeant five had been torn from the ground and hurled in different directions outward from the buildings, leaving only the contents of a sixth and seventh bag which had been emptied in a heap connected with the long train before the others had been laid upon it in a little pile. They were none too soon, for the last bag had hardly been hurled away with all the strength that the young officer could command, and while the sergeant was yelling to him to run, before the hissing fiery serpent was close upon them. Fortunately the sergeant's crawling and the following trampling of the excited pair had broken up and crushed in the regularly laid train, scattering the powder in all directions, so that the rush of the hissing fire came momentarily to an end and gave place to a sputtering and sparkling here and there, giving Lennox and the sergeant time to rush a few yards away in headlong flight. There was a terrific scorching blast, and a tremendous push sent them staggering onward in a series of bounds before they fell headlong upon their faces; while at intervals explosion after explosion followed the fiery blast, the burning fragments setting off three of the other bags, fortunately away from where the pair had fallen. The sergeant was the first to recover himself, and raising his face a little from the ground, he shouted, "Don't move, sir! Don't move! There's two or three more to go off yet." Lennox said something, he did not know what, for he was half-stunned, the shock having had a peculiar bewildering effect. But at the second warning from his companion he began to grasp what it meant, and lay still without speaking; but he raised his head a little, to see that beneath the great canopy of foul-smelling smoke that overhung them the earth was covered with little sputtering dots of fire, either of which, if it came in contact, was sufficient to explode any powder that might remain.
