"I heard you were making pearls," I told him on regaining something of my equanimity, "and thought you might be so good as to tell me about it."

"Come up to the house," he barked, and led the way to a rambling erection of corrugated iron and palm leaves containing, as far as I could make out, a gaping "boy" of uncertain origin, some empty soap boxes, and a microscope.

"There's nothing new in what I'm doing here," he told me over two brimming shells of cocoanut milk, "nothing that the Chinese have not been doing for centuries. The pearl is a disease of the oyster; introduce the disease and you will get a pearl."

"Quite," said I.

"No one has succeeded up to the present," continued Mr. Mumpus, "but there is no reason why it should not be done in time, no reason at all. I am appreciably nearer than I was a year ago, for instance. In the meantime, I am producing the ordinary blisters, or half pearls, with various foundations. You see, the cestoid——"

But I cannot hope to set down here all that this amazing man told me in scientific jargon, as he strode back and forth across his mat-strewn floor.

He was a doctor by profession, had tired of it, and come to the islands to pursue his hobby of pearl culture. He takes an oyster from the lagoon, opens it very carefully by the slow insertion of a wooden wedge, and places a pilule of beeswax against the main muscle. The mantle of the oyster then covers it with mother-of-pearl, and in the course of a few months our friend cuts from the shell a very fair imitation of a half pearl.

But, as most people are aware, the real pearl comes from the flesh of the oyster, and it is on the production of the genuine article that Mr. Mumpus centres his efforts. He breeds oysters in the lagoon and dissects them under the microscope for signs of the parasite that undoubtedly causes the pearl. He injects into the flesh of others all manner of foreign matter.

Down there on his speck of an atoll he treats the oyster as a surgeon treats an interesting case and—who knows?—some day there may burst upon an astonished world the name of a man who can make pearls, and that name will not be Mr. Mumpus.
