Then the whole mass of humanity began to writhe and swell, as a frightened crowd does in the dark, so that every one feels as if all the other people were growing hugely big, as big as elephants, to smother and crush him; and each man makes himself as broad as he can, and tries to swell out his chest, and squares his elbows to keep the weight off his sides; and with the steady strain and effort every one breathes hard, and few speak, and the hard-drawn breath of thousands together makes a sound of rushing wind like bellows as enormous as houses, blowing steadily in the darkness.

'Keep your seats!' yelled Schreiermeyer desperately.

He had been in many accidents, and understood the meaning of the noises he heard. There was death in them, death for the weak by squeezing, and smothering, and trampling underfoot. It was a grim moment, and no one who was there has forgotten it, the manager least of all.

'It's only a fuse gone!' he shouted. 'Only a plug burnt out!'

But the terrified throng did not believe, and the people pressed upon each other with the weight of hundreds of bodies, thronging from behind, towards the little red lights. There were groans now, besides the strained breathing and the soft shuffling of many feet on the thick carpets. Each time some one went down there was a groan, stifled as instantly and surely as though the lips from which it came were quickly thrust under water.

Schreiermeyer knew well enough that if nothing could be done within the next two minutes there would be an awful catastrophe; but he was helpless. No doubt the electricians were at work; in ten minutes the damage would be repaired and the lights would be up again; but the house would be empty then, except for the dead and the dying.

Another groan was heard, and another quickly after it. The wretched manager yelled, stormed, stamped, entreated, and promised, but with no effect. In the very faint red light from the doors he saw a moving sea of black and heard it surging to his very feet. He had an old professional's exact sense of passing time, and he knew that a full minute had already gone by since the explosion. No one could be dead yet, even in that press, but there were few seconds to spare, fewer and fewer.

Then another sound was heard, a very pure strong note, high above his own tones, a beautiful round note, that made one think of gold and silver bells, and that filled the house instantly, like light, and reached every ear, even through the terror that was driving the crowd mad in the dark.

A moment more, an instant's pause, and Cordova had begun Lucia's song again at the beginning, and her marvellous trills and staccato notes, and trills again, trills upon trills without end, filled the vast darkness and stopped those four thousand men and women, spellbound and silent, and ashamed too.

It was not great music, surely; but it was sung by the greatest living singer, singing alone in the dark, as calmly and as perfectly as if all the orchestra had been with her, singing as no one can who feels the least tremor of fear; and the awful tension of the dark throng relaxed, and the breath that came was a great sigh of relief, for it was not possible to be frightened when a fearless woman was singing so marvellously.
