“It's ALL coming down,” Peter tried to say, but he found there was hardly any voice to say it with. And, indeed, just as he spoke, the great rock, on the top of which the walking trees were, leaned slowly forward. The trees, ceasing to walk, stood still and shivered. Leaning with the rock, they seemed to hesitate a moment, and then rock and trees and grass and bushes, with a rushing sound, slipped right away from the face of the cutting and fell on the line with a blundering crash that could have been heard half a mile off. A cloud of dust rose up.
“The 11.29 down hasn't gone by yet. We must let them know at the station, or there'll be a most frightful accident.”
“Let's run,” said Bobbie, and began.
But Peter cried, “Come back!” and looked at Mother's watch. He was very prompt and businesslike, and his face looked whiter than they had ever seen it.
“No time,” he said; “it's two miles away, and it's past eleven.”
“If we only had something red,” Peter repeated, “we could go round the corner and wave to the train.”
“Oh, how hot I am!” she said; “and I thought it was going to be cold; I wish we hadn't put on our—” she stopped short, and then ended in quite a different tone—“our flannel petticoats.”
Bobbie turned at the bottom of the stairs.
“Oh, yes,” she cried; “THEY'RE red! Let's take them off.”
She took the red flannel petticoat from him and tore it off an inch from the band. Then she tore the other in the same way.
“There!” said Peter, tearing in his turn. He divided each petticoat into three pieces. “Now, we've got six flags.” He looked at the watch again. “And we've got seven minutes. We must have flagstaffs.”
It seemed to her that they had been standing there for hours and hours, holding those silly little red flannel flags that no one would ever notice. The train wouldn't care. It would go rushing by them and tear round the corner and go crashing into that awful mound. And everyone would be killed. Her hands grew very cold and trembled so that she could hardly hold the flag. And then came the distant rumble and hum of the metals, and a puff of white steam showed far away along the stretch of line.
“Stand firm,” said Peter, “and wave like mad! When it gets to that big furze bush step back, but go on waving! Don't stand ON the line, Bobbie!”
The train came rattling along very, very fast.
“Oh, stop, stop, stop!” cried Bobbie. No one heard her. At least Peter and Phyllis didn't, for the oncoming rush of the train covered the sound of her voice with a mountain of sound. But afterwards she used to wonder whether the engine itself had not heard her. It seemed almost as though it had—for it slackened swiftly, slackened and stopped, not twenty yards from the place where Bobbie's two flags waved over the line. She saw the great black engine stop dead, but somehow she could not stop waving the flags. And when the driver and the fireman had got off the engine and Peter and Phyllis had gone to meet them and pour out their excited tale of the awful mound just round the corner, Bobbie still waved the flags but more and more feebly and jerkily.
When the others turned towards her she was lying across the line with her hands flung forward and still gripping the sticks of the little red flannel flags.
