" "The Yanks are repairing the railroads," said the man, "and are getting ready for another advance. They have reached the Owl Creek bridge, put it in order and built a stockade on the north bank. The commandant has issued an order, which is posted everywhere, declaring that any civilian caught interfering with the railroad, its bridges, tunnels or trains will be summarily hanged.

"Only a picket post half a mile out, on the railroad, and a single sentinel at this end of the bridge." "Suppose a manÑa civilian and student of hangingÑshould elude the picket post and perhaps get the better of the sentinel," said Farquhar, smiling, "what could he accomplish?"
