"Number 125 is longer; but it ain't hard to catch the general idee of it. 'When the light is extinguished in the morning the keeper must hang the lantern curtains and immediately begin to put the apparatus in order for relighting. While doing this the linen aprons provided for the keeper's use must be worn, that the lens may not suffer from contact with the wearing apparel. The illuminating apparatus must be carefully covered before the cleaning is begun.' Now here's Sammy's apron for you, an' this one is mine," Captain Eph said, as he took the articles in question from a locker, and showed Sidney how to put one on. "These 'ere are the lantern curtains which we'll hang up at sunrise." It was quite like a game, Sidney thought, and he was in high glee by the time Captain Eph was ready to read his rule 126. "Here she is, an' there's a good bit of meanin' to it, lad. 'The lens and the glass of the lantern must be cleaned daily and always kept in the best possible condition. Before beginning to clean the lens it must be brushed with the feather brush to remove all dust. It must then be wiped with a soft linen cloth, and finally polished with buff-skin. If there is oil or grease on any part, it must be taken off with a linen cloth, moistened with spirits of wine, and then polished with a buff-skin. Under no circumstances must a skin which has been wet or damp be used, as this will scratch the lens.'" "The Board seems to be mighty particular about how the work shall be done," Sidney said with a laugh, and Captain Eph replied: "If they wasn't we shouldn't have sich lights in this country as we have got. I ain't claimin' that we're the only nation on the face of the earth who knows how to light a coast; but I will say, an' I've heard the same from masters of foreign vessels, that we do the thing up brown regardless of expense. Listen to rule 127, an' than I reckon it'll be time to turn off the light: 'To clean reflectors, first dust them and then rub with a buff-skin, lightly dusted with rouge powder, kept in a small double bag of muslin; then rub lightly with another skin, and finally with a third, which should be passed over the reflector in a light, quick manner with a circular motion. Leakage of gas from the pipe of the stove used in the watch-room should be carefully guarded against, as this gas will badly tarnish a reflector.' Now we'll turn off the light, stop the clock, an' get to work," and Captain Eph suited the motions to the words. Sidney stood ready with the lantern curtains until the keeper should show him how they ought to be hung, for he had come to believe there was a rule for the most trifling labor, when an exclamation of surprise caused him to turn toward the door in the floor, and he saw the head and shoulders of Mr. Peters, who was surveying the scene with a comical expression on his face. "Have I lost my job?" he cried with a laugh, and Captain Eph replied grimly:
