They went carefully over each beam, and crept again into the dusty cupboards.

“Now we’ll go to the barn,” said Elizabeth.

“What do you expect to find there?”

“I don’t know, but I’m going.”

As Elizabeth had left the attic for the last spot to be visited in the house, so she left the barn chamber as the most promising quarter of the barn. It was a large room on the main floor which had evidently been used at one time as a living-room, for there was an opening in the wall for a stovepipe.

“I think the hired man usually lived in the barn chamber,” said she. “And I suppose the harness was kept in these cupboards. This could easily be put in order for our chauffeur, Herbert!”

Herbert smiled faintly. He had opened the door of one of the cupboards and drew out an old map.

“There’s nothing in here but this, Elizabeth.”

“Let’s unroll it.”

Then Herbert grew white. It was a map of Adams County. From its center Gettysburg and the surrounding country had been cut, or rather slashed, as though it were done hastily with a large knife.
