"There is a way of finding out a cipher," answered Diggory; "it tells you how to do it in that book that we bought when Mug had his things sold by auction at Chatford."

"What, in Poe's tales?" asked Mugford. "Yes; in one of the stories called 'The Gold Bug.' Where is the book?"

"I lent it to Maxton, but I should think he's finished it by this time.
I'll go and see."

"All right," said Diggory, pocketing the slip of paper; "you get it, and then I can show you what I mean. Come on, Jack; let's go out."

The two friends were just rising from the form on which they had been sitting, when they were accosted by Browse, who, strolling up with a pair of dilapidated slippers on his feet, which caused him to walk as though he were skating, inquired in drawling tones, "I say, have either of you kids got a watch-key?"

Jack Vance handed him the required article, which happened to be of the kind which fit all watches.

The Sixth Form "sap" was very short-sighted, and proceeded to wind up his timepiece, holding it close to his spectacles throughout the operation.

"I can't think how it is," he continued, in his sing-song tone,
"I'm always losing my key. I've had two new ones already this term.
I always stick them in a place where I think they're sure not to get
lost, and then I forget where I put them. Thanks awfully."

"What a queer old codger Browse is!" remarked Diggory, as the big fellow moved away; "no one would ever think he was so clever."

"No," answered Jack Vance. "By-the-bye, did you hear that he had another row with 'Thirsty' last night?"
