was more ragged; but they were making a good fight.

The twins' canoe, however, continued to forge ahead. There was little
doubt that they would soon pass their rivals.

And just then Hester uttered an angry cry, dipped her paddle more
deeply, swerved her canoe, and its side came directly in the path of the
twins' boat.

"Look out!" shrieked Lily. "You'll run us down!"

And that is what the twins did.

Crash went their canoe into that of Hester: both boats tipped
alarmingly, and in a moment all four girls were struggling in the lake.

MISS CARRINGTON IN JUDGMENT

"Oh! Oh! I'm drowning!" shrieked Lily Pendleton.

And then the water filled her mouth and she went down with a "blub,
blub, blub" that sounded most convincing.

Hester was sputtering threats and cries, too, and she paid no attention
to her chum, who, although she could swim pretty well, lost her head
very easily in moments of emergency.

The twins said never a word. They had gone under at the first plunge,
but they were up again, shook the water from their eyes, and each took
hold of their boat to right it.

When Lily screamed and went under, however, the Lockwoods chanced to be
even nearer to her than was Hester.

"We've got to get her!" gasped Dorothy.

"Sure we have!" agreed Dora.

And together, leaving their canoe, they dived after the sinking girl.
Lily was not unconscious, and the moment one of the twins grabbed her,
Lily tried to entwine her in her arms.

But thanks to Mrs. Case's earnest efforts in the swimming pool, the
twins knew well how to break the grasp of a drowning person, and the
girl who had been seized by Lily did not lose her head, but immediately
broke the frightened girl's hold and quickly brought her to the surface.

Lily was between Dora and Dorothy, and when she had gotten rid of some
of the water, and opened her eyes, she became amenable to advice.
Together the twins towed her to a launch that came shooting up, and Lily
was hauled inboard. Dora and Dorothy were intending to go back and right
their canoe; but some of the boys had done that for them, and rescued
their paddles and other boat furnishings.

"Let us help you in here, young ladies; then we'll go after that other
girl," offered those on the launch. "The boys will take the canoes back
to the boathouse, and that's where you would better be. There's a cool
wind blowing."

So the twins hoisted themselves over the gunwale of th
