"By Jove, Billie," I said, "this is a dandy!"

"Isn't it!" cried an old familiar voice at my elbow.

I turned as if stung. The spirit was with me again, prepared, I doubted not, for his second twist. I sprang from my seat, a sudden inspiration flashing upon me, jumped back of the revolving fan, and turning the full force of the wind it created upon my vindictive visitant, blew him fairly and squarely into the bulging sail.

"There, blast your cockney eyes!" I cried; "take that."

He tried to retort, but without avail. The wind that emanated from the fan fairly rammed his words back into his throat every time he opened his mouth to speak, and there he lay, flat against the canvas, fluttering like a leaf, powerless to escape.

"Hot air doesn't affect you much, you transparent jackass!" I roared. "Let me see how a stiff nor'easter suits your style of beauty."

I will not bore the reader with any further details of the Lake Worth experience. Suffice it to say that for five hours I kept the miserable thing a pneumatic prisoner in the concave surface of the sail. Try as he would, he could not escape, and finally, when Wilkins and I went ashore for the night, and the cockney ghost was released, he vanished, using unutterable language, and an idea came to me, putting which into operation, I at last secured immunity from his persecutions.

Returning to New York three days later, I leased a small office in a fire-proof power building not far from Madison Square, fitted it up as if for my own use, and had placed in the concealment of a closet at its easterly end the largest electric fan I could get. It was ten feet in diameter, and was provided with sixteen flanges. When it was in motion not a thing could withstand the blast that came from it. Tables, chairs, even a cut-glass inkstand weighing two pounds, were blown with a crash against the solid stone and iron construction back of the plaster of my walls. And then I awaited his coming.

Suffice it to say that he came, sat down calmly and unsuspecting in the chair I had had made for his especial benefit, and then the moment he began to revile me I turned on the power, the fan began to revolve, the devastating wind rushed down upon him with a roar, pinned him to the wall like a butterfly on a cork, and he was at last my prisoner—and he is my prisoner still. For three weeks has that wheel been revolving night and day, and despite all his cunning he cannot creep beyond its blustering influence, nor shall he ever creep therefrom while I have six hundred dollars per annum to pay for the rent and cost of power necessary to keep the fan going. Every once in a while I return and gloat over him; and I can tell by the movement of his lips that he is trying to curse me, but he cannot, for, even as Wilkins's fan blew his words of remonstrance back into his throat, so does my wheel, twice as powerful, keep his torrent of invective from greeting my ear.
