“Doocid queer thing altogether,” said the subaltern, “but look here, if you like, I’ll chuck on the coals and you can drive the old jigamaroo, if she’ll go.”

“Perhaps she will blow up,” said the gunner-guard.

“’Shouldn’t at all wonder by the sound of her. Where’s the shovel?” said the subaltern.

“Oah no. She’s all raight according to my book, I think,” said young Ottley. “Now we will go to Serai Rajgara—if she moves.”

She moved with long ssghee! ssghee’s! of exhaustion and lamentation. She moved quite seven miles an hour, and—for the floods were all over the line—the staggering voyage began.

The subaltern stoked four shovels to the minute, spreading them thin, and Number Forty made noises like a dying cow, and young Ottley discovered that it was one thing to run a healthy switching-locomotive up and down the yards for fun when the head of the yard wasn’t looking, and quite another to drive a very sick one over an unknown road in absolute darkness and tropic rain. But they felt their way along with their hearts in their mouths till they came to a distant signal, and whistled frugally, having no steam to spare.

“This might be Serai Rajgara,” said young Ottley, hopefully.

“’Looks more like the Suez Canal,” said the subaltern. “I say, when an engine kicks up that sort of a noise she’s a little impatient, isn’t she?”

“That sort of noise” was a full-powered, furious yelling whistle half a mile up the line.

“That is the Down Mail,” said young Ottley. “We have delayed Olaf two hours and forty-five minutes. She must surely be in Serai Rajgara.”
