But there was enough serious talk during the supper to arrange a return treat for Eve and Otto Sitz. The farmer boy and his sister had seldom been on Lake Luna and Laura and her brother suggested a trip by boat and canoe to Cavern Island for the following Saturday.
"And no picnic luncheon at the park. That's too common," declared Jess Morse, eagerly. "Let's do something different."
"Trot out your 'different' suggestion, Josephine," said her chum.
"Let's go to the caves. Let's picnic there."
"Oh!" cried one of the Lockwood twins. "That's where we saw the 'lone pirate.'"
"The lone what?" rejoined Nellie Agnew. "What do you mean by that?"
The other twin explained how and when they had seen the bushy-headed, wild-looking man at the foot of Boulder Head.
"There's where the caverns open onto the shore, exactly," remarked Chet Belding. "Are you afraid of meeting the pirate, girls?"
"We'll capture him and make him walk the plank!" declared Bobby Hargrew. "Hurrah for the pirate!"
So the trip to Cavern Island for the next Saturday was arranged, Eve and Otto promising to join the party at Centerport. And the run home by automobile in the moonlight was enlivened by plans for the coming good time on the Lake.
