"It was a convenient disguise, enabling me to do and learn many things. It also made it possible for me to be out in the evening alone, and allowed me to visit certain places where otherwise I should have been any thing but welcome. It also satisfied a spirit of adventure which I possess, and led to the experience which I am now about to relate. Miss Sterling, my brother has one peculiarity. He can be intrusted to carry a message, and forget it ten minutes after it is delivered. This being generally known in town, I was not at all surprised when one evening, as I was traversing a very dark street, I was met and accosted by a muffled figure, who asked me if I would run to Mr. Barrows' house for him. I was about to say No, when something in his general air and manner deterred me, and I changed it into the half-laughing, half-eager assent which my brother uses on such occasions. The man immediately stooped to my ear and whispered: "'Tell Mr. Barrows to come with all speed to the old mill. A man has been thrown from his carriage and is dying there. He wants Mr. Barrows' prayers and consolation. Can you remember?' "I nodded my head and ran off. I was fearful, if I stayed, I would betray myself; for the voice, with all its attempted disguise, was that of Guy Pollard, and the man injured might for all I knew be his brother. Before I reached Mr. Barrows' door, however, I began to have my doubts. Something in the man's manner betrayed mystery, and as Guy Pollard had never been a favorite of mine, I naturally gave to this any thing but a favorable interpretation. I did not stop, though, because I doubted. On the contrary, I pushed forward, for if there was a secret, I must know it; and how could I learn it so readily or so well as by following Mr. Barrows on his errand of mercy? "The person who came to the door in answer to my summons was fortunately Mr. Barrows himself; fortunately for me, that is; I cannot say it was altogether fortunately for him. He had a little book in his hand, and seemed disturbed when I gave him my message. He did not hesitate, however. Being of an unsuspicious nature, he never dreamed that all was not as I said, especially as he knew my brother well, and was thoroughly acquainted with the exactness with which he always executed an errand. But he did not want to go; that I saw clearly, and laid it all to the little book; for he was the kindest man who ever lived, and never was known to shirk a duty because it was unpleasant or hard.
