If you think the first steam engine was a marvel of ingenuity, how much more ingenuity must it have taken to conceive and make the first stone knife.

Do not look down with condescension upon the men of the Old Stone Age, for their culture, by comparison with what had gone before, was greater than yours. Consider, for example, what marvelous inventive genius must have been his who first conceived the idea and then successfully created fire by artificial means. That nameless creature of a forgotten age was greater than Edison .

As our canoe approached the river bank opposite the village, I was unbound; and when we touched I was yanked roughly ashore. The other canoes followed us and were pulled up out of the water. A number of warriors had come down to greet us, and behind them huddled the men and the children, all a little fearful it seemed of the blustering women warriors.

I aroused only a mild curiosity. The women who had not seen me before looked upon me rather contemptuously.

"Whose is he?" asked one. "He's not much of a prize for a whole day's expedition."

"He's mine," said Gluck. "I know he can fight, because I've seen him; and he ought to be able to work as well as a woman; he's husky enough."

"You can have him," said the other. "I wouldn't give him room in my hut."

Gluck turned toward the men. "Glula," she called, "come and get this. Its name is David. It will work in the field. See that it has food, and see that it works."

A hairless, effeminate little man came forward. "Yes, Gluck," he said in a thin voice, "I will see that he works."

I followed Glula toward the village; and as we passed among the other men and children, three of the former and three children followed along with us, all eying me rather contemptuously.

"These are Rumla, Foola and Geela," said Glula; "and these are Gluck's children."

"You don't look much like a man," said Rumla; "but then neither do any of the other men that we capture outside of the valley. It must be a strange world out there, where the men look like women and the women look like men; but it must be very wonderful to be bigger and stronger than your women."
