There was a restless movement on the part of the marines. Those who had been drowsing awakened, to grip more firmly the rifle which, since darkness, no longer held the knife-like bayonet. One man quietly opened the bolt of his rifle and nervously fingered a clip of cartridges in his belt.

"Easy, men!" came the caution down the length of the train, and the slight flutter of nerves calmed to steadiness. But the tension was there, and only the excellent discipline held them in check, for these rebels were too close for comfort. Then followed the slow ringing of the locomotive's bell, brakes were released and the train moved on, crossed a high trestle bridge, and again halted.

"Pile out, everybody! Throw our company stores off the cars at once and stow them alongside the track. Get some lanterns working, men. On the jump, now!" and Captain Henderson strode along the embankment shining his flash-light and encouraging his men to do good work.

Lights flickered along the train. Stores were tossed off in quick order, camp sites selected, police parties immediately prepared latrines, and the guard was posted. Then, the immediate requirements being attended to, the men rolled up in their blankets on the hard earth to get such sleep as they could.

"Who were all those hombres[#] surrounding us before we crossed the big bridge, Sergeant?" asked Dick, pulling his knapsack into a more comfortable position beneath his head.

[#] Hombres--Men.

"They was the chief army of the rebels in these parts," replied Dorlan. "When we stopped back there we were right in the middle of the biggest town in Nicaragua, and the one where all the trouble starts. The people of Leon are always ready to revolute with the hope of makin' it the capital instead of Managua, and bein' on the only railroad from the capital city to the seaport, Corinto, they're in a foine place to control things. The nearest Federal troops are at a place called La Paz, about twenty-three kilometers from here."

"How long is a kilometer, Sergeant?" questioned one of the men.

"It's about five-eighths of a mile, so La Paz would be about fourteen miles south of here. From there on the Federal troops hold the railroad to the southern outskirts of Managua, and as this line goes on to Granada, I figure it's up to us to do considerable of work yet, for they say that we'll never get through the rebel lines beyond the capital without a fight. However, so far things seem to be goin' pretty slick."

"Do you know how many troops there are in Leon, Sergeant?"
