"Oh, girls!" cried Amy, her voice trembling somewhat, "it's getting deeper!"
"It certainly isn't stopping from coming in," murmured Mollie. "Where is that plug!"
Desperately she continued to feel about, while the other girls cast anxious eyes toward the shore, that now seemed so far away.
"And there's not another boat in sight!" exclaimed Betty. "We must call for help!"'
"I have it! I have the plug!" suddenly cried Mollie, pulling on something.
"Ouch! That's my foot—my toe!" cried Grace. "Let go!"
"Oh, dear!" sighed Betty, in disappointed tones.
"I thought I had it!" said Mollie. "Wait until I catch those twins!"
"We—we never may see them again," faltered Amy, whose recent rather tragic experience; had gotten on her nerves.
"Stop that!" commanded Betty, a bit sharply.
