The boys had been in as much apprehension because of the possible return of the occupant of the cave as they had been because of the presence of the men. So now, when one danger was removed, they had time to think of the other. As soon as they thought the men were far enough away for them to venture out, Tom, who was nearest the opening, looked out to see if the way were really clear.

He sprang back in alarm as a great pile of dirt and stones came hurtling down the mountain side with a roar like thunder and with a force that made the ground tremble. The great mass was piled high before the opening of the cave, shutting out every vestige of light and air.

CHAPTER VIII
THE BOY SCOUTS TO THE FORE

“Jack, Jack, where are you?” Tom called wildly, groping around in the inky blackness for his friend.

“Here, old man!” Jack replied from his corner. “I thought from the roar a lion had come to interview us. What has happened, anyway?”

“What has happened? Why, man, it seems as if the whole mountain has slid down to cover the cave. It’s shut out all the air, and we can’t breathe very long with the little we have in here. Why, Jack, do you realize that unless someone finds us in a hurry we will die in this horrible smelling hole like rats in a trap?”

“It sure is some tight place, old fellow, but what we’ve got to do now is to brace up and think of some way to get out.”

“Oh, yes, that sounds all right, but how are we going to do it? Can we dig our way through rocks and dirt with our fingers? Can we change into moles and burrow our way out underground? I tell you, Jack, we’re goners unless somebody discovers us within the next hour at the most.”

“Tom, Tom, don’t talk like that! Brace up and be a man! If we’ve got to face Death, let’s meet him bravely, as a true Scout should. Besides,” he added after a moment’s thought, “don’t you remember the bones that we saw scattered around here the other day? Let’s hunt around and see if we can find some. They might possibly help us to dig our way out.”

The boys searched desperately for a bone big enough to be of service to them. Finally they found a couple that they thought might serve and they set to work fearfully to see what they could do.
