"Ass! You've heard of the box we're going to fix."

"But that's a box. It's not a seat."

"Go on with it, Clive," urged Hugh, looking as if he would willingly slay his brother. "Take no notice of the ass. We start her up, and then get seated."

"On a box."

"Yes," agreed Clive, glaring at Bert, who had again interrupted. "The engine's going. The chain's free-wheeling. We have a lever somewhere."

Hugh pointed out its position with triumph, and the two promptly proceeded to fit the contrivance. But levers are not made in a moment. It was, in fact, noon of the following day before they were ready for an outing.

"You manage the steering, that's agreed?" asked Clive, when the amateur-constructed motor-car had been pushed as far as the road.

"That's it. You control the engine. Don't let her race too much at first. Remember I ain't used to steering. Besides, those front wheels are frightfully groggy. She'll sway at corners, and if we put on the pace I shall be piling the whole bag of tricks up on one of the banks. Bert'll keep cave. There's no police about here to matter. Jimmy, the local constable, 's a real good fellow. He'll see the thing from the right point of view. He knows we're experimenting and'll sympathise."

"Particularly if he's called in at the inquest," gurgled Bert, irrepressible when his chums desired to be so serious.

"Inquest. Eh?" asked Hugh. "What's that?"
