"Sure," said Si confidently. "You watch the other side o' the bridge and I'll look out for the rest."
The eager boys had already begun firing, entering into the spirit of the thing with the zest of a Fame of town-ball. Shorty took Gid Mackall and Harry Joslyn down to the cover of some large stones, behind which they could lie and command the approach to the other end of the bridge with their rifles. Si took the other boys and placed them behind rocks and stumps along the crest and instructed them to fire with as good aim as possible at the flashes from the other side. In a minute or two he had a fine skirmish-line in operation, with the boys firing as deliberately and accurately as veterans. The engineer had backed the train under the cover of the cut, and presently he and the conductor came up with guns and joined the firing-line.
"I say, Shorty," said Si, coming down to where that worthy was stationed, "what d' you think o' the boys now? They take to this like a duck to water. They think it's more fun than squirrel-huntin'. Listen."
They heard Monty Scruggs's baritone call:
"Say, Alf, did you see me salt that feller that's bin yellin' and cussin' at me over there? He's cussin' now for something else. I think I got him right where he lived."
"I wasn't paying any attention to you," Alf's fine tenor replied, as his rammer rang in his barrel. "I've got business o' my own to 'tend to. There's a feller over there that's firing buckshot at me that I've got to settle, and here goes."
"The 200th Injianny Volunteers couldn't put up a purtier skirmish than this," murmured Si, in accents of pride, as he raised his gun and fired at a series of flashes on the farther bank.
"I say, tell that engineer to uncouple his engine and bring it back up here where the head-light'll cover the other side," said Shorty. "It'll make the other side as light as day and we kin see every move, while we'll be in the dark."
"Good idee," said Si, hastening to find the engineer.
He was none too soon. As the engine rolled up, flooding its advance with light, it brought a storm of bullets from the other side, but revealed three men creeping toward the other end of the bridge. Two were carrying pine knots, and the third, walking behind, had a stick of blazing pine, which he was trying to shield from observation with his hat.
