"We'll have to get some more grub before long," was the reply, "or it'll be appetite and nothing else with us. I can eat bacon with the next man, but I don't want to feast on it six days running. What we need, Wade, is variety." "And plenty of it," sighed the other, stretching his tired legs and finding a new position. "The fact is, even after this banquet I feel a little hollow." "Same here, but I figure we'd better go a little short till we get nearer town. We ought to strike Bosa Grande to-morrow night." "Why not hop the train and go down to Aroya? We can find some real grub there." "Couldn't get back before to-morrow afternoon. What's the good of wasting a whole day?" "Looks to me like we'd wasted about twenty of them already, Ed." Craig made no reply. He fished a corn-cob pipe and a little sack of tobacco from his pocket and began to fill the bowl. Wade watched for a moment in silence. Then, with a protesting groan, he rolled over until he could get at his own pipe. Craig drew an ember from the edge of the fire with calloused fingers, held it to his bowl and passed it on to Wade. Then with grunts of contentment they settled back against the sagging canvas of their tent and puffed wreaths of acrid smoke into the twilight. The shadows were creeping up the mountain side. Overhead the wide sweep of sky began to glitter with white stars. A little chill breeze sprang up in the west and fanned the fire, sending a fairy shower of tiny lemon-yellow sparks into the air. And borne on the breeze came a hoarse pounding and drumming that grew momentarily louder and reverberated from wall to wall. The ground trembled and the grazing burros lifted their shaggy heads inquiringly. "She's almost up," said Wade. Craig nodded and replaced his pipe between his teeth. The noise became multisonous. With the clangor of the pounding wheels came the stertorous gasping of the engines, the creak and clatter of protesting metal. The uproar filled the pass deafeningly. "She's making hard work of it," shouted Craig. "Probably a heavy train," Wade answered. Then a path of pale light swept around the elbow of the mountain and the wheezing, puffing monsters reached the head of the grade. The watchers could almost hear the sighs of relief from the two big mountain-climbers as they found the level track beneath them. Their breathing grew easier, quieter as they clanged slowly across the pass a few rods below the camp. The burros, having satisfied their curiosity, went back to supper. The firemen in the cab windows raised their hands in greeting and the campers waved back. Behind the engines came a baggage and express car, then a day coach, a diner and a sleeper. Slower and slower moved the train and finally, with a rasping of brakes and the hissing of released steam, it stopped. "What's up?" asked Wade. "Hot-box on the diner; see it?" "Yes, and smell it. Let's go down."
