As he was entering the Study Hall, Bolax saw Harrison and laughingly told him there was to be an awful "lark" in the dormitory. "We're going to have no end of fun." "Are you?" said Harrison. "Well if it gets amusing, come to my room and tell me, and I'll go down and look on." It was Brother Isadore's night on duty. He walked slowly up and down the range of the dormitories until every boy seemed ready to get into bed, then he put out all the candles (there was no gas to be had and the Brothers would not trust coal-oil lamps to boys). So long as they were under surveillance, the boys observed the utmost quiet and decorum. All continued in order until Brother Isadore passed out through the lavatory, one of the boys following him as a scout, had seen the last glimmer of his hand-lamp disappear around the corner at the foot of the staircase, and heard the library door close behind him. After that, as Brother Director was obliged to preside at the Council, the boys knew they were safe from disturbance, and the occupants of the large dormitory were the first to stir. "Now for some fun," said George, starting up, and by the way of initiative, pitching his pillow at Bolax's head. "I'll pay you for that when I'm ready," said Bo, laughing, "but let us light a few candles first; however, it's bright moonlight, maybe we had better not light up, some one outside might notice our illumination." Several fellows from the dormitory came on the scene with their sconces lit, these they placed so as not to show through the windows. Then the boys began all sorts of amusements, some in their night shirts, others with their trousers slipped on. Leapfrog was the prevalent game for the time, but at last Henry de la Tour suggested theatricals, and they were agreed on. "But we're making a regular knock-me-down shindig," said Fulton, "somebody must keep guard." "Oh, old Brother Isadore is safe enough in the Chapel; no fear of disturbing him if we were dancing Jim Crow," answered Bolax. However it was considered safest to put some one at the top of the stairs in case of an unexpected diversion in that direction, and little Leonce consented to go first. He had only to leave the lavatory door open and stand at the top of the staircase, then he commanded for a great distance the only avenue in which danger was expected. If any Brother's lamp appeared in the hall, the boys had full three minutes' warning and a single loudly whispered "cache-cache" would cause them to "lay low," so that by the time of their adversary's arrival they would, of course, be all fast asleep in bed, some snoring in an alarming manner. So at the top of the stairs stood little Leonce shoeless and shivering in his night shirt, but keenly entering into the fun.
