the open doorway into the cellar. Instantly, the massive door slammed and a pair of heavy bolts were shot in succession on the outside.
"What the devil is the meaning of this?" I roared, battering and kicking furiously at the door. Of course there was no answer, and I quickly stopped my demonstrations, for it dawned on me m a moment that the factory was untenanted save by the ruffian who had admitted me; that I had been decoyed here of a set purpose, though what that purpose was I could not imagine.
But it was not long before I received a pretty broad hint as to the immediate intentions of my host. A gentle thumping at the door of my cellar attracted my attention and caused me to lay my ear against the wood. The sound that I heard was quite unmistakable. The crevices of the door were being filled, apparently with pieces of rag, which my friend was ramming home, presumably with a chisel. In fact the door was being "caulked " to make the joints airtight.
The object of this proceeding was clear enough. I was shut up in an air-tight cavity in which I was to be slowly suffocated. That was quite obvious. Why I was to be suffocated, I could form no sort of guess excepting that I had fallen into the hands of a homicidal lunatic. But I was not greatly alarmed. The air in a good-sized cellar will last a considerable time, and I could easily poke out anything that my friend might stuff into the keyhole. Then, when the men arrived in the morning, I could kick on the cellar door, and they would come and let me out. There was nothing to be particularly frightened about.
Were there any men? The injured man was evidently a myth. Supposing the other men were a myth too? I recalled Maggie's remark, that she "had thought the place was to let still." Perhaps it was. That would be rather more serious.
At this point my agitations were broken in upon by sounds from the adjoining cellar; the sound of someone moving about and dragging some heavy body. And it struck me at once as strange that I should hear these sounds so distinctly, seeing the massive door of my own cellar was sealed and the walls were of solid brick, as I ascertained by rapping at them with my knuckles. But I had no time to consider this circumstance, for there suddenly rose a new sound, whereat, I must confess my heart fairly came into my mouth; a loud, penetrating hiss like the shriek of escaping steam. It seemed to come from some part of the cellar in which I was immured; from a spot nearly overhead; and it was immediately echoed by a similar sound in the adjoining cellar and then by a third. Even as the last sound broke forth, the door of the adjoining cellar slammed, the bolts were shot and then faintly mingled with the discordant hissing. I could hear the dull thumping that told me that the cracks of that door, too, were being caulked.
It was a frightful situation. The hissing sound was obviously caused by the escape of gas under high pressure, and that gas must be entering my cellar through some opening. I felt for my match-box, and, groping along the wall towards the point whence the loudest sound—and, indeed, all the sounds—proceeded, I struck a match. The glimmer of the wax vesta made everything clear. Close to the ceiling, about seven feet from the ground, was an opening in the wall about six inches square; and pouring through this in a continuous stream was a cloud of white particles that glistened like snowflakes. As I stood under the opening, some of them settled on my face; and the more than icy coldness of the contact, told the whole, horrible tale in a moment.
This white powder WAS snow—carbonic acid snow The hissing sound came from three of those great iron bottles, charged under pressure with liquified carbonic acid, which are used by mineral water manufacturers for aerating the water. The miscreant (or lunatic) who had imprisoned me had turned on the taps, and the liquid was escaping and turning into to snow with the cold produced by its own rapid evaporation and expansion. Of course the snow would quickly absorb heat, and, without again liquefying, evaporate into the gaseous form. In a very short time both cellars would be full of the poisonous gas, and I—well, in a word, I was shut up in a lethal chamber.
It has taken me some time to write this explanation, which, however, flashed through my brain in the twinkling of an eye as the light of the match fell on that sinister cloud of snowflakes. In a moment I had my coat off, and was stuffing it for dear life into the opening. It was but a poor protection against the gas, which would easily enough find its way through the interstices of the fabric; but it would stop the direct stream of snow and give me time to think.
On what incalculable chances do the great issues of our lives depend! If I had been a short man I must have been dead in half an hour; for the opening through which the cloud of snow was pouring was well over seven feet above the floor and would have been quite out of my reach. Even as it was, with my six feet of stature and corresponding length of arm, it was impossible to ram my coat into the opening with the necessary force, for I had to stand close to the wall with my arm upraised at a great mechanical disadvantage. Still, as I have said, imperfect as the obstruction was, it served to stop the inrushing cloud of snow. It would take some time for the heavy gas in the adjoining cellar to rise to the level of the opening, and, meanwhile, I could be devising other measures.
I lit another match and looked about me. The cellar was much smaller than I had thought and was absolutely empty. The floor was of concrete, the walls of rough brickwork and the ceiling of plaster, all cracked and falling in. There was plenty of ventilation there, but that was of no interest to me. Carbonic acid gas is so heavy that it behaves almost like a liquid, and it would have filled the cellar and suffocated me even if the top of my prison had been open to the sky. The adjoining cellar was already filling rapidly, and when the gas in it reached the level of the opening, it would percolate through my coat and come pouring down into my cellar. But that, as I have said, would take some time—if the dividing wall was moderately sound. This important qualification, as soon as it occurred to me, set me exploring the wall with the aid of another match; and very unsatisfactory was the result. It was a bad wall, built of inferior brick and worse mortar, and was marked by innumerable holes where wall-hooks and other fastenings had been driven in between the bricks. My brief survey convinced me that, so far from being gas-tight, the wall was as pervious as a sponge, and that whatever I meant to do to preserve my life, I must set about without delay.
But what was I to do? That was the urgent, the vital question. Escape was evidently impossible. There were no means of stopping up the numberless holes and weak places in the wall. The only vulnerable spot was the door. If I could establish some communication with the outer air, I could, for a time at least, disregard the poisonous gas with which I should presently be surrounded.
The first thing to be considered was the keyhole. That must be unstopped at once. Fumbling in my bag—for I had grown of a sudden niggardly with my matches—I found a good-sized probe, which I insinuated into the keyhole; and, in a moment, my hopes in that direction were extinguished. For the end of the probe impinged upon metal. The keyhole was not stopped with rag, but with a plate of metal fixed on the outside. With rapidly-growing alarm, but with a tidiness born of habit, I put the probe back in the bag and began feverishly to review the situation and consider my resources. And then I had an idea; only a poor, forlorn hope, but still an idea.
There is a certain ingenious type of pocket-knife, devised principally in the interest of the cutlery trade, that innocent persons (usually of the female persuasion) are wont to bestow as presents on their masculine friends. Such a knife I chanced to possess. It had been given to me by an aunt, and sentimental considerations had induced me to give it an amount of room in my trousers' pocket that I continually grudged. However, there it was at this critical moment, with its corkscrew, gimlet, its bewildering array of blades, its hoof-pick, tooth-pick, tweezers, file, screw-driver and assorted unclassifiable tools; a ponderous lump of pocket-destroying uselessness—and yet, the appointed means of saving my life.
The gimlet was the first tool that I called into requisition. Very gingerly—for these tools are commonly over-tempered and brittle—I bored in the thick plank a hole at about the level of my mouth; and as I worked I turned over my further plans. When the gimlet was through the door, I selected a tool on whose use I had often speculated—a sharp-edged spike, like a diminutive and very stumpy bayonet—which I proceeded to use broach-wise to enlarge the hole. When this tool worked loose, I exchanged it for the screwdriver, with which I managed to broach the hole out to about half an inch in width. And this was as large as I could make it, and it was not large enough. True, one could breathe fairly comfortably through a half-inch hole, but, with the deadly gas circulating
