Then, in my desperation, I took the flat stick again, and pulled with it in the water, and the boat went farther, and soon, as I looked about, I saw that I was close to the wood on the other side of the lagoon. I pulled with the flat stick again, and the boat touched land again, and I climbed out and lay down upon the ground.

Long I thought. Could the flat stick make the boat go back? I would try. I clambered into the boat, and turned it about with the pole, so that it pointed toward the other shore, and then took the stick and pulled with it in the water again, and was carried back to very nearly the place from which I had started. I sprang upon the bank, and yelled and leaped up and down. I wonder why it is that men always dance up and down and yell when they are happy? The other creatures do not act in that foolish way.

So I danced and whooped, and then, finally, I became tired. But I was the greatest man in the tribe. I alone had the flat stick, and none should take it from me. There was another flat stick lying on the shore, and I took it up in sport, and got into the boat with it, laughing, because I knew it would not make the boat move. I was wrong. I pulled with it as I had with the other, and, behold! the boat moved as it had done before! Other flat sticks I took then, and pulled with them, and the boat obeyed them all. Any flat stick would move the boat, if it were only to be pulled with the flat side against the water. I was no richer than any other man of the tribe. Then I tried to move the boat with round sticks—many of them—but it lay still. The sticks simply glided through the water, and the boat would not heed them.

I shouted again, still more loudly, because I wanted to tell about the flat stick, and Thin Legs came running from the wood where he had been gathering nuts and roots. No game had he, for Thin Legs does not often hunt, though he alone can chip the best arrow-heads and spear-heads. I told him of the wonderful flat stick, and all it had done, and there came the thinking look in his eyes which I do not understand, and then he tried the flat stick himself in the boat, and then climbed ashore and leaped and shouted almost as wildly as I had done. After a time he sat down upon a little rock, and sat there long, saying no word, holding the flat stick in his hand, and looking at it. He could think long. It did not hurt his head as it did mine, and the heads of others of the Cave men, if we thought too much. Then we went to the caves together. Thin Legs carried with him the flat stick, but he said nothing.

When I left the cave the next morning the big yellow thing that makes the light had not yet come up above the great forest to the east. I could not wait. I was too eager to try to go upon the water again with a flat stick to move the boat. I ate but a mouthful or two of the flesh of the little deer I had killed in the ravine in the hills, and then I ran to where were the boat and the flat sticks. I took my bow and arrows with me. I would get across the lagoon, and go into the beech wood where many birds fed on the nuts, and where it was good hunting. There was no boat there! Then there came to my ears a yell from the other shore.

I called aloud in answer, and from the shadow of the distant bushes across the water came out the boat with Thin Legs kneeling in it, and digging the water, as it seemed, with a flat stick again, and the boat was coming toward me. But far more swiftly and straight it came than it had done the day before, and I knew in a moment that Thin Legs, the wise, had been at work in the night, at work by his fire in the cave, and that, somehow, he had given more strength to the flat stick.

It was the same flat stick at one end, but not at the other. The day before it had been hard to grasp and hold, because it was so broad, and I could not get my fingers round it. I could hold it only with a hard clutch, pressing on each side, and so could not pull it through the water without a strain. Now it was another kind of stick. All night long Thin Legs had worked with his stone hatchet and with his knife. For what would be the length from a man’s foot to his knee he had chopped and chipped on each side of the wood until there was left something that could be clasped easily in the hand, and this part he had cut and scraped until it was round, like a spear-handle. At the end was still a flat stick with which a man could pull in the water with all his strength, grasping the round handle above. No man had seen such a stick before, and I spoke not, though Thin Legs grinned.

“We will call it a paddle—which means what pulls,” he said, and grinned again. “Get into the boat.”

I got into the boat, and took the strange stick, and dug it into the water, and pulled swiftly with all my might, and the boat shot away as do some of the swimming birds upon the water; for now I had my grip and I was strong. I went to the other shore, and, very swiftly, back again. What a thing had we!

And another paddle made Thin Legs, so that we each had one, and day by day we learned about the boat and the flat stick, until, when we pulled together, we went over the water like the queer clacking water bird of the rushes, which need not fly from danger, so swiftly can it swim.
