Take it, and commit them to heart, and then tear the paper into shreds, and burn them.

As far as Roxburgh you can, of course, ride as my squire; but beyond, you must travel in disguise.

This you had better procure here, and take with you; for although the Governor of Roxburgh is a trusty knight, it were best that no soul should know that you go on a mission to March; and I shall simply give you a letter to him, stating that you are engaged in a venture in my service, and that your horse and armour are to be kept for you, until your return." Thanking Lord Percy for the honour done him, in selecting him for the mission, and promising him to carry it out, to the best of his power, Oswald retired and, making his way up to an inner room, set about learning the contents of the paper given him, which was, indeed, a copy of the royal letter to Percy.
