"Possibly," said the Archdeacon very gravely, "the terminal nuts of your dry battery were loose."

Mr. Blinks moved slowly away.

"Dear me!" he mused, "how changed they are."

It was a relief to him to edge his way quietly into another group of guests where he felt certain that the talk would be of quite another kind.

Professor Potofax and Miss Scragg and a number of others were evidently talking about books.

"A beautiful book," the professor was saying. "One of the best things, to my mind at any rate, that has appeared for years. There's a chapter on the silencing of exhaust gas which is simply marvellous."

"Is it illustrated?" questioned one of the ladies.

"Splendidly," said the professor. "Among other things there are sectional views of check valves and flexible roller bearings—"

"Ah, do tell me about the flexible bearings," murmured Miss Scragg.

Mr. Blinks moved on.
