By and by, while Scheich Ibrahim was entertaining the fair Persian with some discourse, Noor ad Deen took his turn to desire him to light up some of the candles in the lustres, not taking notice that all the wax-lights were already in a blaze. "Certainly," replied Scheich Ibrahim, "you must be very lazy, or less vigorous than I am, that you are not able to light them yourself; get you gone, and light them; but be sure you light no more than three." To work he went; but instead of that number, he lighted them all, and opened the shutters of the fourscore windows, before Scheich Ibrahim, who was deeply engaged with the fair Persian, knew any thing of the matter.
