`` Well , '' said Jack , `` all we can do is to mind our own business and pay no attention to him at all , Pete , unless he bothers us . If he lets us alone , why , we 'll do the same by him . '' Then they went downstairs , and Jack found a note left for him by Durland . `` I have left orders that you are not to be awakened , unless you wake up yourselves , before three o'clock , '' the Scout-Master had written ; `` you three have had plenty of work , and you are entitled to a good rest . The Troop will be on scout duty near Tryon Creek , but your orders are to use the car , and reconnoiter in the direction of Mardean . The fighting will swing the Blue center over in that direction , unless we are badly beaten , and your orders are to keep a close watch on the roads leading to Fessenden Junction . It is possible that General Bliss may make a raid in that direction , probably with his cavalry brigade .
