“I strained my ears, and from the outside I could hear a rumbling that seemed to come from far, far away.
“‘It’s the machinery!’ I cried. ‘It’s after one o’clock, and they have begun work again. No wonder they couldn’t hear us!’
“By that time I had become really frightened, and I suppose I must have temporarily lost my head. I shouted wildly until my throat was sore, but it seemed only to fill our oven trap with noise. There was no hope whatever that it would penetrate the thick brick walls. Suddenly I was startled into silence by a sound of scraping iron underneath us—a familiar noise to my ears. Some one had pulled open the great damper that shut us off from the fires in the cellar below! They were going to heat our oven!
“‘What was that?’ exclaimed my sister, touching my hand with her cold fingers. ‘What did that noise mean, Bob?’ She seemed to know our danger by instinct. I did not answer, for with a sinking heart I felt on my face the first breath of warm air!
“‘Tell me, Bob!’ demanded Margaret. ‘They are heating this oven, aren’t they?’ She had caught my wrist and pressed it as hard as a girl could squeeze.
“‘Yes!’ I gasped, trying to speak bravely. I remember I felt that if I were alone I should not care nearly so much, but the idea that my little sister would have to die, too, put me into another panic.
“A second breath of air a good deal hotter than the first fanned my cheek. I jumped up with a scream, and beat and kicked upon the rough brick walls and on the iron door in blind terror. Then, exhausted, I crawled along the floor to the place where Margaret sat. She was crying quietly—I could tell because when I put my arm about her I could feel that she was shaking.
“‘They will never, never hear us!’ she sobbed.
“‘Don’t cry, Margy,’ said I, patting her wet cheek while I tried to arouse my own courage. ‘Perhaps there is another way.’
“I tried to think, but the heat had then become almost unbearable; it stung my nose and seemed to suffocate me. Once when I touched a place on one of the tiles I drew my hand back in real pain. There was no hope of breaking the latch of the iron door, and no one could hear us, though we put our mouths to a little crack at the top of the door and screamed. I was sure we would be baked. My arm was still round my sister, and her hand was still in mine, as if she were seeking the comfort of the touch.
