The big girls had been out in the boat and Ruth had left Agnes to bring up the oars and crab nets, as well as to moor the boat, while she hastened to get dinner.

The tide being on the turn they could not very well pull the boat up to the mooring post; but there was a long painter by which it could be tied to the post. Agnes, however, carried the oars up to the tent and then forgot about the rest of her task as she dipped into a new book.

Tess and Dot came to the empty boat and at once climbed in. Tom Jonah objected at first. He ran about on the sand—even plunged into the water a bit, and put both front paws on the gunwale.

If ever a dog said, “Please, please, little mistresses, get out of the boat!” old Tom Jonah said it!

But the younger Corner House girls paid no attention to him. They went out to the stern, which was in quite deep water, and began clawing overboard with the crab nets. With a whine, the dog leaped into the craft.

Now, whether the jar the dog gave it as he jumped into the boat, or his weight when he joined the girls in the stern, set the cedar boat afloat, will never be known. However, it slid into the water and floated free.

“We can catch some crabs, too, maybe, Tess,” Dot said.

Neither of them noticed that the oars were gone, but had they been in the boat, Tess or Dot could not have used them—much. And surely Tom Jonah could not row.

They did not even notice that they were afloat until the tide, which was just at the turn, twisted the boat’s nose about and they began drifting up the river.

“Oh, my, Dot!” gasped Tess. “Where are we going?”
