"Yes, I was reading about that while we were on the way here, but somehow didn't remember the name of the one who had done it," Jack went on, while the little motor boat and the new-fangled contraption that seemed perfectly at home in the air or floating on the waves kept company on the tide of the river.

"Did I understand you to say that you would be willing to do me a little favor, if it didn't put you to much inconvenience?" asked Spence, his voice trembling with an eagerness that Jack could not help noticing.

"Certainly we will, if it lies in our power," he answered promptly.

"They never was a more obliging gossoon in the wide worrld than this same Jack Stormways, and ye can depind on that!" exploded Jimmy, thinking it about time he injected his personality into the conversation, since he did not wish to be an utter nonentity.

Malcolm Spence thrust a hand into his tightly buttoned leather coat. When he brought it out Jack saw that it held what looked like a small packet, which, after all, might be a letter, though it was sealed.

"I wanted to get this to a party by the name of Van Arsdale Spence," he said, hurriedly, as though afraid that they might back out after all from their kind proposition; "but I knew he no longer lived in Beaufort, and I had no means of finding his present address. So, instead of mailing it, I have carried the thing around with me for three weeks, intending when I went South to make inquiries and send it to his new address, if so be he was far away."

"All right, then," declared Jack, stretching out his hand promptly; "I'll promise to do everything in my power to get it into his possession. Failing, you must give me some address through which I can reach you, to tell you it was no go."

"Here's my card, with the address of the makers of this machine. A letter will always get to me if sent in their care, because, you see, I'm under a three years' contract to exhibit this invention, and add new ideas of my own. But I do hope you may be able to find the party. I'd like that packet to fall into his hands as soon as possible. Too much time has already been lost. Please keep it safe, will you, Jack?"

The skipper of the Tramp accepted the little packet in a serious manner that no doubt impressed the other favorably.

"Depend on me to do my level best for you; that's all any fellow could promise, Mr. Spence," he said, simply, as he stowed the article away in an inside pocket of his coat.
