EDGAR RICE BURROUGHS

after the hardships we had endured among the peaks of the Mountains of the Clouds—we came upon a broad flood that rushed majestically onward in the direction of the great sea we had seen from the snowy slopes of the mountains.

For three long marches we followed the left bank of the growing river, until at last we saw it roll its mighty volume into the vast waters of the sea. Far out across the rippling ocean we descried three islands. The one to the left must be Anoroc.

At last we had come close to a solution of our problem—the road to Sari.

But how to reach the islands was now the foremost question in our minds. We must build a canoe.

Perry is a most resourceful man. He has an axiom which carries the thought-kernel that what man has done, man can do, and it doesn't cut any figure with Perry whether a fellow knows how to do it or not.

He set out to make gunpowder once, shortly after our escape from Phutra and at the beginning of the confederation of the wild tribes of Pellucidar. He said that some one, without any knowledge of the fact that such a thing might be concocted, had once stumbled upon it by accident, and so he couldn't see why a fellow who knew all about powder except how to make it couldn't do as well.

He worked mighty hard mixing all sorts of things together, until finally he evolved a substance that looked like powder. He had been very proud of the stuff, and had gone about the village of the Sarians exhibiting it to every one who would listen to him, and explaining what its purpose was and what terrific havoc it would work, until finally the natives became so terrified at the stuff that they wouldn't come within a rod of Perry and his invention.

Finally, I suggested that we experiment with it and see what it would do, so Perry built a fire, after placing the powder at a safe distance, and then touched a glowing ember to a minute particle of the deadly explosive. It extinguished the ember.

Repeated experiments with it determined me that in searching for a high explosive, Perry had stumbled upon a
