But they did invade. A modern ship is a complex affair. How was I to guess the manner of the invasion?

It was two in the morning, and for an hour I had been puzzling my head with watching the smoke arise from the after-division of the for’ard-house and with wondering why the mutineers should have up steam in the donkey-engine at such an ungodly hour. Not on the whole voyage had the donkey-engine been used. Four bells had just struck, and I was leaning on the rail at the break of the poop when I heard a prodigious coughing and choking from aft. Next, Wada ran across the deck to me.

“Big trouble with Buckwheat,” he blurted at me. “You go quick.”

I shoved him my rifle and left him on guard while I raced around the chart-house. A lighted match, in the hands of Tom Spink, directed me. Between the booby-hatch and the wheel, sitting up and rocking back and forth with wringings of hands and wavings of arms, tears of agony bursting from his eyes, was Buckwheat. My first thought was that in some stupid way he had got the acid into his own eyes. But the terrible fashion in which he coughed and strangled would quickly have undeceived me, had not Louis, bending over the booby-companion, uttered a startled exclamation.

I joined him, and one whiff of the air that came up from below made me catch my breath and gasp. I had inhaled sulphur. On the instant I forgot the Elsinore, the mutineers for’ard, everything save one thing.

The next I know, I was down the booby-ladder and reeling dizzily about the big after-room as the sulphur fumes bit my lungs and strangled me. By the dim light of a sea-lantern I saw the old steward, on hands and knees, coughing and gasping, the while he shook awake Yatsuda, the first sail-maker. Uchino, the second sail-maker, still strangled in his sleep.

It struck me that the air might be better nearer the floor, and I proved it when I dropped on my hands and knees. I rolled Uchino out of his blankets with a quick jerk, wrapped the blankets about my head, face, and mouth, arose to my feet, and dashed for’ard into the hall. After a couple of collisions with the wood-work I again dropped to the floor and rearranged the blankets so that, while my mouth remained covered, I could draw or withdraw, a thickness across my eyes.

The pain of the fumes was bad enough, but the real hardship was the dizziness I suffered. I blundered into the steward’s pantry, and out of it, missed the cross-hall, stumbled through the next starboard opening in the long hall, and found myself bent double by violent collision with the dining-room table.

But I had my bearings. Feeling my way around the table and bumping most of the poisoned breath out of me against the rotund-bellied stove, I emerged in the cross-hall and made my way to starboard. Here, at the base of the chart-room stairway, I gained the hall that led aft. By this time my own situation seemed so serious that, careless of any collision, I went aft in long leaps.

Margaret’s door was open. I plunged into her room. The moment I drew the blanket-thickness from my eyes I knew blindness and a modicum of what Bert Rhine must have suffered. Oh, the intolerable bite of the sulphur in my lungs, nostrils, eyes, and brain! No light burned in the room. I could only strangle and stumble for’ard to Margaret’s bed, upon which I collapsed.
