"It won't come to be known," said Peter; "we aren't sneaks. All the same you oughtn't to sleep on duty—it's dangerous."

"Tell me something I don't know," said the man, "but I can't help it. I know'd well enough just how it 'ud be. But I couldn't get off. They couldn't get no one to take on my duty. I tell you I ain't had ten minutes' sleep this last five days. My little chap's ill,—pewmonia, the Doctor says,—and there's no one but me and 'is little sister to do for him. That's where it is. The gell must 'ave her sleep. Dangerous? Yes, I believe you. Now go and split on me if you like."

"Of course we won't," said Peter, indignantly, but Phyllis ignored the whole of the signalman's speech, except the first six words.

"You asked us," she said, "to tell you something you don't know. Well, I will. There's a boy in the tunnel over there with a red jersey and his leg broken."

"What did he want to go into the blooming tunnel for, then?" said the man.

"Don't you be so cross," said Phyllis, kindly.

"We haven't done anything wrong except coming and waking you up, and that was right, as it happens."
