"You have all seen what has happened to-day," he said quietly. "A bright, innocent, harmless child murdered simply because he was working for us. We hardly deserve the name of human if we do nothing to avenge his death. It is getting too near night to do anything to-day, but I am going to call for volunteers to go with me to-morrow morning to either capture his murderers or wipe them out of existence. Who will go with me?"
His chums and the two engineers stepped promptly to his side, and the Spaniards followed one by one.
"Good," said the lad, with a sad smile. "We will start at daylight."
There was no singing or laughter in the camp that night, for each man carried to his tent with him the reflection that the morrow might see him as dead as the Indian child they were going to avenge. There were plenty of men to act as guards for the night now that the machine was not working, so Charley retired early to his tent and soon fell asleep. At daybreak the guards awoke him and his companions as they had been ordered to do, and reported that the night had passed off without alarms. Chris soon had breakfast ready and over cups of strong steaming coffee their plans for the expedition were made.
When the sun arose ten Spaniards and seven Americans armed with guns and pistols filed out of the little camp and silently tramped away for where a distant smudge of smoke showed the location of the gunmen's campfire. Only enough more remained behind to guard the camp.
The little party of avengers advanced with caution. They marched in a twisting line so as to always keep a hummock or a bunch of spruces between them and the distant camp smoke so that their approach would not be noticed. As they slowly drew nearer double caution was observed, but at last they came upon an open stretch of prairie which they must cross to reach the thicket in which the gunmen's camp was located.
"Here is where they take the alarm," commented Charley, as they emerged out upon the open prairie.
But the little party crossed the open stretch without any sign of life from the gunmen.
"They have either moved or are sound asleep," he said. "Get your guns ready. Don't fire unless I give the word. Follow me, and make as little noise as you can."
