"Oh, if they can only do it! If they can only do it!" Nan said over and over to herself as she beat her hands one upon the other and stared after the racing boats. "I wish Jo were stroke. She'd manage the trick some way."

But in this she did Sadie an injustice. Sadie might not be as good as either of her chums on the tennis courts. But in a boat, with the oars in her hand, she was a different person.

They had reached the island. Ruth and Carol were in the lead, with two of the other boats trailing close behind. Sadie and Jo brought up the rear. A poor chance for victory, it would seem, with Jo and Sadie apparently quite out of the race.

But this was far from the fact. Sadie had deliberately allowed her boat to fall behind so that she would be able to seize the desired opening when it came.

It came!

"All ready, Jo?" called Sadie softly.

"Ready!" returned Jo.

They had reached that portion of the lake where the water off shore was deepest. A gap showed between the third boat and the island. It was through this gap that Sadie and Jo must force their boat if they hoped to make the inside of the course.

Having conserved their strength, they had it for use now. Swiftly their oars flashed in the water. Rapidly the gap closed up between them and the leading boat. They worked as they had never worked before, bending their backs to the task.

Carol and Ruth guessed their intention—but too late.
