“Much worse,” Dick told him, resolutely. “Whenever you feel your knees beginning to get weak under you, just shut your eyes and see father, mother and little Mary sitting by the fireside at home. It will do wonders. I know, for I have often tried it myself.”

By this time the Indians had finished binding their arms behind them. Evidently they expected to go to some other place to camp.

The day was not far from its close. Dick wondered whether they were to be taken to the place where Jasper Williams was being held prisoner. Lascelles had said it was a camp where his son Alexis and some other Frenchmen were in charge, showing that he must wield considerable influence over the warlike Blackfeet.

There was nothing to indicate what the result of the pursuit of Mayhew had been, up to the time they started forth. This in itself gave the boys a faint hope the guide might have eluded his pursuers. They had considerable faith in Mayhew, and believed that he would not desert them.

Still, what could one man do against such a legion of enemies, and especially when in almost as much fear of the wonders of that enchanted region as the superstitious Indians themselves?

Some of the Indians walked ahead, while others brought up the rear, once they started. Dick was curious enough to take note of the course they pursued. He had a dogged faith to believe that sooner or later he would want to know something about this ground, for he hoped to tread it again on the return journey to the explorers’ camp.

It was, he found, a difficult task to keep track of their passage. This was chiefly caused by the meanderings of the Indians. Whenever they fancied they were approaching one of the spouting wells, with its steam column, and its roaring voice, they would sheer off to one side, and circle around it.

All this made their course an eccentric one, and Dick found it beyond his power to figure it out. All he could do was to note the general direction in which they were heading, and store it away in his memory for future use.

Roger was close enough to him to allow of an occasional interchange of remarks. Their captors seemed to pay no attention to what they were saying; and of course none of them understood a word of it, so the boys saw no need of restricting themselves when discussing their hopes and fears.

“I believe they intend to camp before long,” Dick said presently, as they continued to move along through the pine-clad side of the slope that rose to form a foothill to the mountain chain further away.
