When the roller broke on the shallow shore, Biff was tossed off in the foaming breaker. He grabbed his board and held on until the wave smoothed out.

“Gee! That’s the most thrilling ride I’ve ever had!” he exclaimed.

“You did great, Biff,” Li said. “But just wait. If you think that was a charge, wait till you ride the board standing up. How about it?”

“Let’s go!” Biff agreed promptly.

Out they went again. Again they waited for the right feel of the roller. Biff felt one take his board. He was speeding shoreward. He looked over the water at his friend. He saw Li rise to a knee crouch, then slowly straighten up until he was standing straight, head held high.

Biff tried it. He got to his knees. Carefully feeling for his balance, he started straightening up. “I’ve done it,” he said triumphantly to himself. He looked shoreward just in time to catch a blinding splash of salt spray. He blinked his eyes, and the next thing he knew, he was floundering in the water.

Li, seeing what had happened, leaped off his board, turned it, and came paddling back to Biff.

“I meant to tell you. When you get up, hold your head high, and back. Then the salt spray doesn’t hit you in the eyes.”

Now you tell me,” Biff said, laughing. “I’m going to make it this time.”

They started out even. Li got up first. Biff took seconds longer. He was more careful this time. The tough part was straightening up from a crouching position to an erect one, then placing one foot ahead of the other, and getting a good balance. Biff arose slowly, slowly but surely. He made it. The two boys rode standing up, only a few feet separating their two boards.
