I could not believe it, and expected each moment to see it come back to the surface; but no, there was no bladder visible; and, having reloaded, my uncle sent another afloat, bidding me wait till it was farther away before I fired.

I obeyed him and missed. Fired again and missed, but the third time the bladder collapsed and sank, and my reputation as a marksman was made.

The French passengers would have petted and spoiled me had not my uncle interfered; and when we were once more alone he began to talk of my success.

“You quite exceeded anything I expected, Nat,” he said smiling. “How you managed it, my boy, I cannot tell. The first time I set it down to pure accident; but when you repeated it again and again, all I can say, my boy, is that your eyes must be wonderfully good, and your aim and judgment even better. I doubt with all my practice whether I could have been more successful.”

“I think it must have been chance, uncle,” I said, “for I seemed to have no time to aim, and the vessel heaved up so just then.”

“No, my boy,” he replied, “it was not chance, but the result in a great measure of your practice with your gun; but you will not always shoot so well as that. When you come to be out with me in the wilds of one of the islands we visit, and have perhaps been tramping miles through rough forest, you will find it hard work to hit the object at which you aim.”

“But it will be easier to shoot from the ground than from on shipboard, uncle, will it not?”

“For some things yes, my boy, for others no. But wait a bit, Nat, and we shall see.”

The practice was kept up all through our voyage, and I became quite an adept at breaking floating bottles and other objects that were sent over the side, for the bladders soon came to an end; but our voyage was very uneventful. It was always enjoyable, for there was so much that was fresh to see. I never complained about the heat, which was very great, although people were lying about under awnings, while I used to get into the chains, or the rigging below the bowsprit, so as to gaze down into the wonderfully clear water and watch the dolphins and bonita as they darted through the sunlit depths with such ease and grace.

Sometimes I have wished that I could be a fish, able with a sweep or two of my powerful tail to dart myself through the water just as I pleased, or float at any depth, keeping up with the huge steamer as it was driven on.
