and, when she thought the proper time had come, she started her motor on the reverse.
For a moment it seemed that, even with this, the Gem would not come off the bar, and the girls looked anxiously over the side to detect the first motion.
Then there came a quiver to the stranded boat, and a shout from the colored men:
"She's movin', boss!"
"Turn on a little more gas!" cried the steersman to Betty. "I think we have her now!"
She speeded up her motor, and in another instant the Gem came free so suddenly that there was danger of a collision.
"Shut down!" called Hank Belton quickly. "You're all right now."
Betty turned off the power, and Mollie cast loose the tow rope.
"Thank you very much," she called to the man.
"I wish you would let us pay you," added Betty.
"Nary a pay, Miss," was his answer. "I'm glad I could help you. Just give my message to Mr. Stonington, and I'll be obliged to you. Better back down a bit before you turn. That bar sticks out a ways. It's a wonder you didn't hit it before. You can't draw much."
