Frederick took the opportunity to make a few scathing remarks to Percival.

"It's just like you, you mouldy old citron," he said. "I start a little experiment in tirage de jambe, and you put your heavy hoof in and spoil the whole business. You know jolly well that Le Glaxo was completely closed down months ago."

"Oh, put another penny in your brain-meter and try to realise that you aren't the only one who's grown up," replied Percival impatiently. "Your brain-waves move about as quick as G.P.O. telegraph messages. I'd got the scheme worked out while you were putting over your old musical-comedy gags."

Since the departure of the British, Le Glaxo's only excitement is the arrival of its one train per day. Ignoring the sensation caused by the detraining of four persons simultaneously, Percival led his party along a muddy rough lane.

"The dump is about four kilometres away and the road gets rather bad towards the end," he said, maliciously edging Wuffle into a bit of swamp. "Sorry; I was going to warn you about that."

Wuffle scraped mud from his trousers and followed the leader over a rough wall into a hidden ditch. A breathless climb up a hill and a steady trudge over plough-land found Wuffle still game, but, after he had got his camera ready for action on the cheerful assurance that they were nearing their quarry, a disappointed cry from the leader dashed his hopes.

"Hang it!" said Percival, "I forgot. The dump was moved to Pont Antoine last Tuesday. Come along; it's only three kilometres away."

Strangely enough, Pont Antoine was also a blank. Binnie suggested trying Monceau, two kilometres further on; but when they arrived there, fatigued and dirty, a thin drizzle was falling and it was almost dark. Percival confessed himself baffled.

"I'm awfully sorry," said he to Wuffle; "I can't find it now, and the point is how are we going to get back? There isn't a railway for miles."

"Don't any of our lorries or cars pass here?" asked Wuffle.
