"At the main camp north of Corbie," answered Ralph. "Colonel Winston knows us, and he has promised to get us in the artillery."

"Then you really want to be put to work!" asked the commandant.

"Yes; that is why we left the aviation service, after our friend was killed," said Alfred.

"How would our battery suit you?" asked the commandant with a smile.

"Oh, it would be just what we want," answered Ralph quickly. "We can do anything; if you'll only try us."

"Then come along and help us tomorrow when we alter our range," said the commandant.

"Here, Frisky! come on!" said Alfred, as the animal was still pawing and sniffing around. "I suppose he can go along, too, may he?"

The group was immensely amused at the request. "We might make him the mascot of the battery," said one of them.

As they were walking up the hill, one of the great guns resounded, soon followed by another crash.
