Frank came down on top of Bob, and before either could rise, Casco and Raymond were upon them.

“We have them,” said Raymond.

“Don’t you dare to move!” cried the scar-faced man.

The darkness was unfavorable to any kind of fair fighting, and every one went in as best pleased him. Casco was a powerful man, but Bob was thoroughly aroused, and he fought so skilfully that the scar-faced man was soon retreating.

The young photographer followed him up, thus becoming separated from Frank and Raymond.

At length Casco turned and fled toward the brook, and jumping over, disappeared in the brush and darkness beyond.

Bob knew it would be folly just at present to attempt to follow the man, and after a moment’s hesitation he returned to the spot where he had left Frank and Raymond.

The two had disappeared!

“Hullo, Frank!” called out the young photographer. “Where are you?”

No answer came back to the cry save the baying of a couple of hounds in the barn, and Bob at once became more alarmed.
