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.
The engine-driver picked her up, carried her to the train, and laid her on the cushions of a first-class carriage.
"Gone right off in a faint," he said, "poor little woman.

And no wonder.
I'll just 'ave a look at this 'ere mound of yours, and then we'll run you back to the station and get her seen to." It was horrible to see Bobbie lying so white and quiet, with her lips blue, and parted.
"I believe that's what people look like when they're dead," whispered Phyllis.
"DON'T!" said Peter, sharply.
They sat by Bobbie on the blue cushions, and the train ran back.
