Then commending the result to God, I set my candle carefully at the foot of the door, just below the spot where all my little grooves converged. At once the flame ran up them, the naphtha kindling angrily with a spatter and a hiss. The blue light showed in livid ghastliness all the horrors of the chamber. The naphtha was burnt in a moment, it seemed to go off like gunpowder; from a prudent distance I threw more upon it, and soon I had the delight of seeing a steady flame established. The lumps of tallow were burning now, and the wood began to smoulder. Several times I thought that I must be choked by the smoke, till it went in a cloud to the windows, and streamed away under the sacks. As the fire grew and grew, and required no more feeding, I lay on my face, to get all the air possible, at the further end of the room, where my loose mortar was scattered. I could feel my heart thumping heavily on the pavement, and my breath was shorter and shorter, as much from fear as from smoke. If once I became insensible, or even if I retained my senses but failed to extinguish the fire, nothing more would ever be known or heard of Clara Vaughan; there would be nothing even to hold an inquest upon. I must burn ignobly, in the fat of that dreadful porpoise, and with the crocodile, and all those grinning beasts, so awful in the firelight, making faces at me! Surely it must be time, high time to put it out; that is to say if I could. Once let the flame gather head on the other side of the door, and with my scanty means I never could hope to quench it. At last, I became so frightened, that I hardly let it burn long enough. It was flaring beautifully, and licking deeper and deeper (with ductile wreathing tongues and jets like a pushing crocus), the channels prepared to tempt it; and now the black wood was reddened, and a strong heat was given out, and the blazes began to roar; when I cast on the centre suddenly my doubled blanket, and propped it there with the pillow. After a few vain efforts, the flames, deprived of air, expired in gray smoke; then I removed the scorched blanket, and let the smouldering proceed. The charring went on nicely for perhaps a quarter of an hour, and the smell made me think of bonfires and roast potatoes; and I gouged away with the claw of the holdfast, until I saw that, by a vigorous onset, a large piece might be detached; so I stepped back and ran at it with a mighty kick, and with a shower of dust and sparks, a great triangle flew out before my "military heel." At the risk of setting myself on fire, though gathered in the smallest possible compass for a girl rather full in the chest, I squeezed through the hole in the door, and met face to face old Cora.
