Then a feminine voice called:
"Hello, Frank Merriwell. You are a dandy!"
"Thank you," said Frank, laughing. "There are others."
"Not in your class," was the quick retort. "You are the only one of the kind."
"Who was that?" asked Diamond, as the boat passed on.
"Couldn't tell you, my boy," answered Frank.
"Why, that's strange! She spoke to you as if she knew you. Familiar for a stranger!"
"Evidently she is intoxicated—by the moonlight," grunted Browning.
"If we stay down this way long, I fancy we'll find there is considerable freedom at these summer resorts," said Merry. "People do not always wait for introductions down here. But the girl in that boat would not have spoken had it been in the daytime. She knew I could not recognize her, and that is how she ventured to do it."
