“How long will this ghost keep?” I inquired.
“Oh, about four, five hundled years, maybe,” was his reply. “Ghost now change from spilit to matter, and comes under legality of matter as usual science.”
“What are you going to do with her?” I asked.
“Send him to Buddhist temple in Japan. Old pliest use him for high celemony,” was the answer.
My next desire was to obtain some of Hoku Yamanochi's ghost-powder and analyze it. For a while it defied my attempts, but, after many months of patient research, I discovered that it could be produced, in all its essential qualities, by means of a fusion of formaldehyde and hypophenyltrybrompropionic acid in an electrified vacuum. With this product I began a series of interesting experiments.
As it became necessary for me to discover the habitat of ghosts in considerable numbers, I joined the American Society for Psychical Research, thus securing desirable information in regard to haunted houses. These I visited persistently, until my powder was perfected and had been proved efficacious for the capture of any ordinary house-broken phantom. For a while I contented myself with the mere sterilization of these specters, but, as I became surer of success, I began to attempt the transfer of ghosts to receptacles wherein they could be transported and studied at my leisure, classified and preserved for future reference.
Hoku's bellows I soon discarded in favor of a large-sized bicycle-pump, and eventually I had constructed one of my own, of a pattern which enabled me to inhale an entire ghost at a single stroke. With this powerful instrument I was able to compress even an adult life-sized ghost into a two-quart bottle, in the neck of which a sensitive valve (patented) prevented the specter from emerging during process.
My invention was not yet, however, quite satisfactory. While I had no trouble in securing ghosts of recent creation—spirits, that is, who were yet of almost the consistency of matter—on several of my trips abroad in search of material I found in old manor houses or ruined castles many specters so ancient that they had become highly rarefied and tenuous, being at times scarcely visible to the naked eye. Such elusive spirits are able to pass through walls and elude pursuit with ease. It became necessary for me to obtain some instrument by which their capture could be conveniently effected.
The ordinary fire-extinguisher of commerce gave me the hint as to how the problem could be solved. One of these portable hand-instruments I filled with the proper chemicals. When inverted, the ingredients were commingled in vacuo and a vast volume of gas was liberated. This was collected in the reservoir provided with a rubber tube having a nozzle at the end. The whole apparatus being strapped upon my back, I was enabled to direct a stream of powerful precipitating gas in any desired direction, the flow being under control through the agency of a small stopcock. By means of this ghost-extinguisher I was enabled to pursue my experiments as far as I desired.
So far my investigations had been purely scientific, but before long the commercial value of my discovery began to interest me. The ruinous effects of spectral visitations upon real estate induced me to realize some pecuniary reward from my ghost-extinguisher, and I began to advertise my business. By degrees, I became known as an expert in my original line, and my professional services were sought with as much confidence as those of a veterinary surgeon. I manufactured the Gerrish Ghost-Extinguisher in several sizes, and put it on the market, following this venture with the introduction of my justly celebrated Gerrish Ghost-Grenades. These hand-implements were made to be kept in racks conveniently distributed in country houses for cases of sudden emergency. A single grenade, hurled at any spectral form, would, in breaking, liberate enough formaldybrom to coagulate the most perverse spirit, and the resulting vapor could easily be removed from the room by a housemaid with a common broom.
