"She will not sink, Dale," said the mate, quietly; and as a feeling of confidence on that question made me feel better, the fire suddenly flamed up in one place, burning briskly with a good deal of crackling and sputtering, making me feel doubtful of the ship's stability on that side. Mr Brymer gave me a nod, meant for encouragement, as he went on-- "All the force of the powder went upwards, as it usually does. If it had been dynamite, the explosion would have struck down, driving out the bottom, and then of course the ship would have sunk." "But the fire!" I said; and the anxiety I felt affected my voice, making it sound husky. "Oh, the fire," he said coolly. "We must fight that. It is dangerous, but the explosive spirit has burned out, or been destroyed; the powder has gone, and we have nothing to fear now but the slow working of our friend or enemy, whichever you make it." "But it may burst out furiously at any moment." "It may, my lad, but I hardly think it possible. Of course a great deal of the cargo is highly combustible, but things will not burn quickly without room and plenty of air. Fire shut in only smoulders, and eats its way slowly, as you see it there. Come, I think we may hail the boat, and get our friends on board." "But do you think it will be safe?" "Safer than leaving them in an open boat." "But the mast--the main-mast? Suppose the fire has eaten its way through that?" "If it had the mast would fall; but the fire has worked forward, and, as far as I can see, the mast is untouched. Run up to the main-top, it is clear now. Have a look round, to see if you can make out the two boats with our friends." I looked at him sharply, and he laughed. "Not afraid that the main-mast will give way with your weight, are you?" I felt the colour burn in my cheeks at this, for he had read my thoughts exactly; and without another word, I sprang to the side, climbed above the main-chains, and made my way upwards. But I had not gone far before, as I rose higher and more over the burning hold, I became aware of a hot, stifling fume, and the irritating smoke which rose from beneath me. But I persevered, and though it increased for a time, a few feet higher still the oppressive sensation of breathing these hot fumes grew less; and by the time I had reached and climbed into the top, the smoke was so much dissipated as to trouble me very little indeed. The moment I was up I laid hold of a rope and began to look round, my eyes falling, naturally enough, first upon our boat lying a short distance away, with Mr Frewen, who had just awakened, bending over Walters; and I watched him anxiously, to see if I could make out how my messmate was. But I was brought back from thoughts of him and his position by the mate's voice, as he hailed me from the deck.
