The column swept past me, over the bank, plunging to its historic fate. The cut was piled full of frenzied, scrambling specters, as rank after rank swept down into the horrid gut. At last the ditch swarmed full of writhing forms and the carnage was dire.

My assistants with the extinguishers stood firm, and although almost unnerved by the sight, they summoned their courage, and directed simultaneous streams of formaldybrom into the struggling mass of fantoms. As soon as my mind returned, I busied myself with the huge tanks I had prepared for use as receivers. These were fitted with a mechanism similar to that employed in portable forges, by which the heavy vapor was sucked off. Luckily the night was calm, and I was enabled to fill a dozen cylinders with the precipitated ghosts. The segregation of individual forms was, of course, impossible, so that men and horses were mingled in a horrible mixture of fricasseed spirits. I intended subsequently to empty the soup into a large reservoir and allow the separate specters to reform according to the laws of spiritual cohesion.

Circumstances, however, prevented my ever accomplishing this result. I returned home, to find awaiting me an order so large and important that I had no time in which to operate upon my cylinders of cavalry.

My patron was the proprietor of a new sanatorium for nervous invalids, located near some medicinal springs in the Catskills. His building was unfortunately located, having been built upon the site of a once-famous summer hotel, which, while filled with guests, had burnt to the ground, scores of lives having been lost. Just before the patients were to be installed in the new structure, it was found that the place was haunted by the victims of the conflagration to a degree that rendered it inconvenient as a health resort. My professional services were requested, therefore, to render the building a fitting abode for convalescents. I wrote to the proprietor, fixing my charge at five thousand dollars. As my usual rate was one hundred dollars per ghost, and over a hundred lives were lost at the fire, I considered this price reasonable, and my offer was accepted.

The sanatorium job was finished in a week. I secured one hundred and two superior spectral specimens, and upon my return to the laboratory, put them up in heavily embossed tins with attractive labels in colors.

My delight at the outcome of this business was, however, soon transformed to anger and indignation. The proprietor of the health resort, having found that the specters from his place had been sold, claimed a rebate upon the contract price equal to the value of the modified ghosts transferred to my possession. This, of course, I could not allow. I wrote, demanding immediate payment according to our agreement, and this was peremptorily refused. The manager's letter was insulting in the extreme. The Pied Piper of Hamelin was not worse treated than I felt myself to be; so, like the piper, I determined to have my revenge.

I got out the twelve tanks of Waterloo ghost-hash from the storerooms, and treated them with radium for two days. These I shipped to the Catskills billed as hydrogen gas. Then, accompanied by two trustworthy assistants, I went to the sanatorium and preferred my demand for payment in person. I was ejected with contumely. Before my hasty exit, however, I had the satisfaction of noticing that the building was filled with patients. Languid ladies were seated in wicker chairs upon the piazzas, and frail anemic girls filled the corridors. It was a hospital of nervous wrecks whom the slightest disturbance would throw into a panic. I suppressed all my finer feelings of mercy and kindness and smiled grimly as I walked back to the village.

That night was black and lowering, fitting weather for the pandemonium I was about to turn loose. At ten o'clock, I loaded a wagon with the tanks of compressed cohorts, and, muffled in heavy overcoats, we drove to the sanatorium. All was silent as we approached; all was dark. The wagon concealed in a grove of pines, we took out the tanks one by one, and placed them beneath the ground-floor windows. The sashes were easily forced open, and raised enough to enable us to insert the rubber tubes connected with the iron reservoirs. At midnight everything was ready.

I gave the word, and my assistants ran from tank to tank, opening the stopcocks. With a hiss as of escaping steam the huge vessels emptied themselves, vomiting forth clouds of vapor, which, upon contact with the air, coagulated into strange shapes as the white of an egg does when dropped into boiling water. The rooms became instantly filled with dismembered shades of men and horses seeking wildly to unite themselves with their proper parts.

Legs ran down the corridors, seeking their respective trunks, arms writhed wildly reaching for missing bodies, heads rolled hither and yon in search of native necks. Horses' tails and hoofs whisked and hurried in quest of equine ownership until, reorganized, the spectral steeds galloped about to find their riders.
