“And it’s a good thing I heard them hollering, and got the boat ready,” said the well-dressed lad, whose attire was now rather disheveled from the haste of rowing.

“That’s right, Percy.  I’ll give you credit for that.”

“Oh, do hurry, boys!” cried Mollie.  “We’ll be under in another minute.”

“Coming!” cried Will.  “Pull harder, Percy!”

“I can’t!”

“You’ve got to!” That seemed to be all there was to it.  Percy pulled harder.

Only just in time did Will and his companion reach the boat that was on the verge of sinking.  And only the skill and good sense of the girls, and the knowledge that they could swim if they happened to fall into the water, enabled the rescue to be made.  For it was no easy task to disembark from one craft to the other, especially with one nearly submerged.  But, while Will and Percy held the gunwale of their boat close to that of the half-sunken one, the girls carefully crawled out and soon, rather wet, considerably dismayed, but, withal, calmer than might have been expected, the quartette was safe in the larger craft.

“Oh, what a relief!” exclaimed Mollie, wringing some water from the bottom of her skirt.

“But look at my dress—­and this is only the second time I’ve worn it!” cried Grace, in distress.  “It will be ruined.”

“All it needs is pressing,” said Will, disdainfully.

“What do you think this is—­a pair of your trousers?” demanded his sister, indignantly.  “Pressing!  It is ruined!”

“We’re all drenched,” spoke Amy.  “But it doesn’t matter as long as we’re safe.”

“That’s the way to look at it!” exclaimed Will.  “How did it happen, anyhow?”

“Plug out of the bottom,” explained Mollie, sententiously.  “The twins!”

“I see!  Say, she’s going down all right!” This Will remarked as the boat from which the girls had climbed settled lower and lower in the water.

“Oh, can’t we save it?” cried Mollie.  “My poor boat!”

“I’ll use one of the oars as a buoy,” said Will.  “I’ll fasten it to the painter.  It will probably drift, but it will run into the eddy at the Point, and we can get it to-morrow.”

Quickly he knotted the end of the painter about one of the oars.  Then taking the others into the craft that Percy had commandeered for the occasion, the two boys rowed the girls back to the dock at the foot of the slope that led to Mollie’s house.

“Come in, girls,” she invited.  “We can get dry, and Will can go for some decent things for you three.”

“I’ll go, too!” exclaimed Percy, eagerly.  And for once the girls were glad of his services.

Up the walk went the four bedraggled ones.  The twins saw them coming, and, grave-eyed and solemn, came down to meet them.

“Oo’s wet,” remarked Dodo.

“Drefful wet,” echoed Paul.

“Yes, you naughty children!” scolded Mollie.  “Why did you take the plug—­the wooden peg—­out of sister’s boat?  Why did you do it?”
