"I've thought of that, Roger. But what if we slip when we get out? Why, the bottom of the valley is quarter of a mile further down. I don't want such a tumble, on top of the one we have already experienced."

"If we ever get out we'll have plenty of news to send home," was the senator's son's comment.

"True; but let us get out before we think of sending news."

They talked the matter over, and at length concluded to do a little more exploring of the cave. Dave turned up the pocket lantern as high as possible, and as he did this Roger took from his pocket a short, strong cord. "I thought this might come in useful, for tying up our supplies," explained the senator's son, "so I brought it from the last house we stopped at. Tie one end around your waist, Dave, and I will hold fast to the other end. Then I'll walk behind you, and if you go into a hole——"

"I may drag you behind me," finished Dave.

"No, I'll look out for that,—only be as careful as you can."

"I'll take no more risks than are necessary."

They moved forward slowly and cautiously, first to one side of the cavern and then to the other. At last they struck what appeared to be a passageway running parallel to the mountain side.

"Let us follow this," suggested Dave. "It may bring us out somewhere on the road."

Roger was willing to do anything his chum suggested. It was a hard journey, over rocks that were sharp and slippery. In some spots they found a coating of ice and above their heads long icicles hanging from the roofing. Roger slipped and fell and came down with such a jar that a great icicle weighing at least twenty pounds came down close to his head, smashing into many pieces and scattering over both him and Dave.
