The brother and sister rode on through the valley they had traveled before and up to the top of the ridge from which they had seen the cabin by the side of the stream. The cabin was now in truth deserted. There was no fire before it and not a person in sight.
"Maybe those Indians took them captive. The poor little baby!" murmured Rose.
"Don't be a little dunce, Rose!" exclaimed Russ, with exasperation. "You know that nice Black Bear would not hurt them. And, anyway, I guess that baby was only a doll. That is what that soldier said when you told him about it. He said it was Mr. Props' rag baby."
"Who do you suppose Mr. Props is?" asked Rose. "And Mrs. Props? It must have been Mrs. Props we saw holding the--er--baby. For maybe it was a real baby."
Russ saw there was no use in arguing on this point. He urged his calico pony forward and Pinky followed promptly. The two Bunkers went along the trail past the cabin and up the next slope. They struck into a woodsy sort of road then, and by and by the children saw that the trail was leading them to a ravine between two steep hills. There was much shrubbery, so they could not see very clearly what was before them, but as they continued to ride on there came suddenly a lot of noise from the ravine. Horses whinnied, men shouted, and two or three guns were discharged.
"Oh! It's a fight, Russ!" shrieked Rose. "Do come away!"
But Russ had seen something that interested him very much. Among the bushes on one side of the ravine he saw several Indians creeping. They wore feathers in their scalp-locks, and had bows and arrows and guns. He did not see Black Bear with this company of Indians, but they were acting just as though they were fighting somebody down in the bottom of the ravine.
"It's an--an ambush, Rose!" cried Russ excitedly. "Oh! There's a man with a machine----"
In fact he saw two men with boxes on tripods, standing side-by-side and not many yards away in the trail. The men were turning cranks on the sides of the boxes.
Another man turned and saw the Bunker children apparently riding nearer. He started back toward them, shouted and waved his arms.
"Oh, dear me!" shrieked Rose. "It's--it's dynamite! They are going to blow up something! Come, Russ!"
