and desolate country. Food, some blankets—their guns—as much of the gold as they could hastily gather together—their weapons and some ammunition—all this was carried from the cabin outside the cave. The entrance was rapidly growing smaller. The roof was already pressing down on the gas-bag.
Tom gave one last look at his fine craft. There were tears in his eyes. He started into the cabin for something he had forgotten. Mr. Parker grabbed him by the arm.
"Don't go in!" he cried hoarsely. "The cave will collapse in another instant!" He rushed with Tom out of the cavern, and not a moment too soon. The others were already outside.
Then with a rush and a roar, with a sound like a great explosion, with a rending, grinding and booming as the great pieces of ice collapsed one against the other, the big ice cave settled in, as does some great building when the walls are weakened!
Down crashed the roof of the ice cave! Down upon the Red Cloud, burying out of sight, forever, under thousands of tons of ice and snow, the craft which was the pride of Tom Swift's heart! It was the end of the airship!
Tom felt a moisture of tears in his eyes as he stood there in the midst of the snowstorm.
