"Wonder what he's going to show us to-night," queried Fred.

"Mebbe he's got some more ideas about the Thunder Bird that he didn't tell us," suggested Dunk.

"He's a prince anyway," Jerry exclaimed. And in this all the boys agreed.

Fly had to go back to his work, and it was decided to call up Herb Phipps and Tender Gray, telling them to come over that evening on the aviator's special invitation. Dunk said he would notify Carlito.

At eight that night all the boys met at Jerry's and went together to Mr. Hawke's quarters on the third floor of the old barracks. Graystock wore his tenderfoot badge, while Fred had pinned on all his medals, including the one for aviation.

Carlito, Herb Phipps and his cousin edged into the room somewhat timidly, but the aviator's cordial greeting caused them instantly to forget their embarrassment.

"I'm glad you managed to round up the bunch," Hawke said, after the new trio had been presented. "This lesson won't have to be repeated. And," he continued, observing Fred's decorations, "all of you scouts ought to be wearing aviation badges soon. That is, if you give careful attention to what I'm going to tell you."

"We'll listen, all right," promised Fred. "That's what we're here for."

Hawke smiled. "That reminds me. You fellows came pretty near missing the surprise I've got for you. When Ike went down to Silver City they told him my trunks hadn't come. He waited, however, and they arrived on the next train. He delivered them only a few minutes ago."

The boys exchanged glances of inquiry. What had Ike and the trunks to do with it?
