It was a moment to be remembered: first, because the picture presented to my eyes was of a marked and impressive character; and secondly, because something in the expression of the gentleman before me showed that he had received a shock at my introduction which was not to be expected after the pains which had been taken to prepare his mind for my visit. He was a tall, remarkable-looking man, with a head already whitened, and a form which, if not bowed, had only retained its upright carriage by means of the indomitable will that betrayed itself in his eyes. Seen against the rich background of the stained-glass window that adorned one end of the apartment, his stern, furrowed face and eagerly repellant aspect imprinted itself upon me like a silhouette, while the strong emotion I could not but detect in his bearing, lent to the whole a poetic finish that made it a living picture which, as I have said, I have never been able to forget. "You have come from the constable of the town," said he, in a firm, hard tone, impressive as his look. "May I ask for what purpose?" Looking around, I saw the servant had disappeared. "Sir," said I, gathering up my courage, as I became convinced that in this case I had a thoroughly honest man to deal with, "you are going to give a fancy ball to-night. Such an event is a novelty in these parts, and arouses much curiosity. Some of the men about town have even been heard to threaten to leap the fences and steal a look at your company, whether you will or not. Mr. White wants to know whether you need any assistance in keeping the grounds clear of all but your legitimate guests; if so, he is ready to supply whatever force you may need." "Mr. White is very kind," returned Mr. Benson, in a voice which, despite his will-power, showed that his agitation had in some unaccountable way been increased by my communication. "I had not thought of any such contingency," he murmured, moving over to a window and looking out. "An invasion of rowdies would not be agreeable. They might even find their way into the house." He paused and cast a sudden look at me. "Who are you?" he abruptly asked. The question took me by surprise, but I answered bravely if not calmly: "I am a man who sometimes assists Mr. White in the performance of his duties, and in case you need it, will be the one to render you assistance to-night. A line to Mr. White, if you doubt me----" A wave of his meagre hand stopped me. "Do you think you could keep out of my house to-night, any one I did not wish to enter?" he asked. "I should at least like to try." "A ticket is given to every invited guest; but if men are going to climb the fences, tickets will amount to but little."
