“You take the key with you,” said Henry Burns, “and lock the door on the inside. It’s just an extra precaution; but I can say I don’t know who has the key, if anything happens. I won’t know which one of you takes it.” The four boys stowed themselves away in the stuffy closet, turned the key in the lock, and waited. Henry Burns quickly divested himself of his clothing, put a bowl of water beside his bed, placed a clean white handkerchief near it, set a lamp near by on a chair, turned it down so that it burned dim, unlocked his door so that it could be opened readily, and jumped into bed. He did not have long to wait. Promptly at a quarter past ten o’clock the heavy, lumbering steps of the corpulent colonel were heard, as he came up the hallway. The colonel was puffing with the exertion which it always cost him to climb the stairs, and muttering, as was his custom when anything displeased him. “Suppose they’ll bang away on that old piano half the night,” he exclaimed, as he passed Henry Burns’s door. “And every light burning till midnight. How do they expect me to make any money, if they go on this way?” He opened the door to his room and went inside, locking it after him. Henry Burns pressed his ear close to the wall and listened. The colonel, still talking angrily to himself, scratched a match and lighted one of the lamps. Then he divested himself of his collar and tie, threw his coat and waistcoat on a chair, and reseated himself, to take off his boots. All at once they heard him utter a loud exclamation of disgust. “What on earth is the matter with that lamp?” he cried. “That comes of having hired help from the city. Never look after things, unless you keep right after them. How many times have I spoken about having these lamps filled every day!” The colonel scratched a match. “Hulloa,” he exclaimed, “it’s full, after all. Well, I see, the wick hasn’t been trimmed. There’s always something wrong.” The colonel proceeded to scrape the wick. Then he scratched another match. The wick sputtered as he held the match to it. “Confound the thing!” yelled the colonel, now utterly out of temper. “The thing’s bewitched. Where’s that other lamp? Oh, there it is. We’ll see if that will burn. I’ll discharge that housemaid to-morrow.” He scratched still another match, held it to the wick of the other lamp, and was evidently satisfied with that, for they heard him replace the lamp-chimney and go on with his undressing. In a few minutes more there came another eruption from the colonel. “There goes the other one,” he yelled. “I know what’s the matter. Somebody’s been fooling with those lamps. I’ll make ’em smart for it.” The colonel unscrewed the part of the lamp containing the wick, took the bowls of the lamps, one by one, over to his window, opened them, and poured the contents of the lamps out upon the veranda.
