"We should have had the City Band down to give you a proper send-off," Joe Hardy remarked.
"It doesn't matter. We'll forgive you this time. But be sure and have the band here to welcome us when we come back."
"You'll be back by to-morrow night," declared Iola. "I know you! Why, I'll bet you'll both be scared green when darkness comes on. One night will cure you of sleeping in the open."
"Rats!" replied Chet good-naturedly. "I'm not afraid of the dark."
"Cut out the jawing and let's get started," said Biff Hooper. "No use hanging around here. Are you ready?"
"All set!"
"Let's go then. Good-bye, everybody."
"Good-bye!" every one shouted. Frank and Joe cheered, the girls clapped their hands, and the Envoy slowly moved away from the dock, with Chet Morton and Biff Hooper waving to their chums.
Tony Prito swung his motorboat around.
"I'll go along with you to the end of the bay," he shouted.
