"It couldn't," said Cousin Tom. "I tied it myself, and I am a good enough sailor to know how to tie a boat so it won't work loose."
"Yes, I guess you are," said Mr. Burnett. "The youngsters must have loosened the rope themselves. Or some older children did it, for those two are pretty small," and he looked at Margy and Mun Bun, for the motor-boat was now quite near the drifting rowboat.
"All right, Margy! All right, Mun Bun! We'll soon have you back safe!" called Daddy Bunker to them, waving his hands. Both children were crying.
Up alongside the drifting rowboat went the lobster craft. Cousin Tom caught hold of the boat in which the children sat, and held it while Daddy Bunker lifted out Margy and her brother.
Then the rowboat was tied fast to the stern of the other boat, which was steered around by Mr. Burnett, and headed up the inlet.
"I've got time to take you back to your pier," he said to Cousin Tom. "I started out a bit early this morning, so I don't have to hurry. Besides, the tide is running pretty strong, and you'd have it a bit hard rowing back."
"It's a good thing you came along," said Daddy Bunker, as he thanked the lobsterman. "The children might have been carried out to sea."
"Oh, the life guard at the station on the beach would have seen them in time," returned Mr. Burnett. "But I'm just as glad we got them when we did."
"What made you go off in the boat?" asked Daddy Bunker of Margy.
"We didn't mean to," answered Mun Bun. "We got in to play sail, and the boat went off by itself."
