"That's it," cried Billy.
"It's just this way," resumed the old sailor drawing out his aged pipe. "Yer see, my pardner, James Melville,—that's the poor feller that's dead,—and me was trying out his new air-craft when we got blown out ter sea. We'd been goin' fer two days when you picked up the wireless call for help he was sending out. I used ter say that wireless was a fool thing ter have on an air-ship, but I owe my life ter it all right.
"Ter go back a bit, I met Melville soon after we got back from the treasure hunt. He was a friend of my sister's husband and as full of ideas as a bird dog of fleas. But he didn't have no money to carry out his inventions and as I had a pocketful I couldn't exactly figure how to use, I agreed to back him in his wireless dirigible. We tried her out several times ashore and then shipped her to Floridy, meaning to try to fly to Cuba. But day afore yesterday while we was up on a trial flight the wind got up in a hurry and at the same moment something busted on the engine and, before we knew where we was, we was out at sea."
"You must have been scared to death," put in Professor Sandburr who was an interested listener.
"Not at first we wasn't. Poor Melville in fact seemed to think it was a fine chance to test his ship. He managed to tinker up the engine after working all night and part of yesterday on it and as we had plenty to eat and drink on board—for we had stocked the boat up preparatory to flying to Cuba—we didn't worry much.
"Howsomever, early this morning, after we'd had the engine going all night we found we was still in the same position and for a mighty good reason—one of the blades of the propeller had snapped off and there we were,—practically just where we'd been the night before and with no chance doing anything but drift about and wait for help. Melville never lost his nerve though.
"'We'll be all right, Ben,' says he to me, and though I didn't feel near so confident, still I chirped up a little for I had been feeling pretty blue, I tell you.
"Right after we had had a bite to eat he starts in hammering away at the wireless, sending out calls for help while I just sat around and hoped something would turn up. Some observations we took showed that we had not drifted very much further from land in the night on account of there being no wind. This looked good for it meant that we were, or should be, in the path of ships. The only thing that worried me was that mighty few coasting vessels carry wireless, and I was surprised when we got an answer from what I knew later was the Southern Cross.
"It was just as Melville was getting your answer that I noticed the bag. The air had grown hot as an oven as the sun rose higher and about noon I looked up just to see if there wasn't a cloud in the sky that might mean a storm, and perhaps a change of wind that maybe would blow us back over land again. What I saw scared me. The bag was blown out as tight as the skin of a sausage, and it didn't look to me as if it could swell much more without busting.
"I pointed it out to Melville and he went up in the air—worried to death.
