"I don't believe it comes out," said Braithwaite, while Dick admitted with a grin that he had left it untouched.

"Did you have a shot at it, Hartland?" asked Temple.

"Yes," said Jim; "it seemed easy enough, unless I misunderstood it." And with paper and pencil he proceeded to work it out.

"O my aunt!" cried Dick, who was very fond of bringing that worthy person into his conversation "I believe you've got it, Jimmy!"

"Yes," said Temple, "it certainly looks right. That will give you a lift, Hartland; it counts twenty marks."

"Well," replied Jim, thinking of the morning's work, "I shall need them all."

Presently the groups began to break up, and the boys to disperse. Jim still seemed very gloomy, and even his lively little chum found it difficult to bring a smile to his face.

"You haven't to go to the shop, have you?" he asked.

"Not to-night."

"That's jolly; we'll have a good game down at the Old Fort. It's ages since you were down, and the fellows will be glad to see you. Say you'll come, just to please me."
