“Have you found that pearl?” he asked smilingly; for we had often talked of the possibility of being rewarded with a fortune-bestowing gem.

“Yes, indeed, I have; and a real beauty. I very much doubt if you, for all your experience, ever saw such perfect shape and fine lustre. Here is an instance of the perversity of Chance. You, tied up in a rubber bag, rake the floor of the Barrier, fighting sharks and being hustled by turtle, and never find anything out of the way. I stroll about the beaches, and see what Fortune bestows!”

The size of a small marble, it lay swathed in white wadding. Minute furrows sculptured the surface in radiating lines from pole to pole, enhancing rare radiance.

The captain took the little casket in his hand that he might gloat over the treasure, as, his eyes shining, he said:

“You lucky fellow! Where did you get it? I never saw a finer pearl, and I have seen a few in my days. Fair numbers have passed through my hands; but—you fraud!”

He lifted it, revealing a counterfeit, which had once ornamented a hatpin.

In good-humour he settled down on a lounge and gradually drifted into reminiscences.

“About two years before what I am going to tell you happened, I heard of a patch of shell off an island Sud-Est way; I kept the tip to myself, determined to work the spot on my own account if ever I got the chance. I waited till I saved a few pounds, and, taking in a mate, fitted out a craft, and with a crew of very fair boys sailed away. I found the spot all right; but—my usual luck—someone had been there before me. Strange to say, the spot was by no means worked out, though it was fairly good ground and easy working, and the shell large. We did good business for a while, until one day I got a proper start. The life-line fouled on something, and I found that it had taken a turn round the bowsprit of a wreck. I got on top pretty quick, and, having had a talk with my mate, went down again. Very soon I knew the boat. It was the ——, and she had belonged to a man I had known very well. The strange part about the business was that the boat had been burned. Her deck was gone; she had burned to the water's edge and had sunk, and there she rested on her keel. I knew that the owner had left port some months before on a secret cruise. Someone must have given him the tip, too. He was well known and liked, and generally did good business. My mate and I talked over the business. We wanted to clean up that patch, so decided to remain a few days longer before clearing out to report. I was convinced that murder had been committed-that the natives of the island had massacred the party and had sunk the lugger.

“While I was below next day an urgent message came down. I bobbed up pretty quickly. A boat was sneaking out from the beach, apparently with the plan of cutting us off from our lugger, which was anchored some distance off, with only a couple of boys on board. You bet, we got up steam pretty quickly. When we got on board we reached for our rifles, and then felt safe.

“The boat was then making straight for us, and it appeared to be crowded with darkies. We had been off the island for four days, and had not seen the sight of a native. I knew there were plenty, and the fact that they had kept away had made me a bit suspicious. As the boat came along I was sure they meant mischief, and was determined, no matter how friendly they wanted to be, not to let one of the beggars on deck.
