AN OLD READER.--We do not think it would serve any good purpose to publish a list of the serial stories which have appeared in GOLDEN DAYS since the first issue. They average more than twenty complete serials to the volume, and the titles are included in the annual index. If you, who have read the paper since the first volume, wish to refresh your memory, indexes will be sent you free, on receipt of your real name and address. D. EMBE.--Rotting tree-stumps may be easily removed in this way: With a one-and-a-quarter-inch auger, bore a hole in the centre of the stump, eighteen inches deep, and put in twenty ounces of saltpetre; fill the hole with water and plug it tight. In the spring, take out the plug, pour into the hole a half-pint of crude petroleum and set it on fire. The stump will burn and smolder to the end of the roots, leaving nothing but ashes. H. H. P. L.--From No. 1, of Vol. 13, up to No. 33, of the same volume, the following-named serials were begun. The Young Engineer, The Hermit's Protege, Little Miss Muffet, An Unpremeditated Journey, Johnny Henry's Cruise on the Spanish Main, The Mystery of Valentine Stanlock, Lost In a Ceylon Jungle, Adrift From Home, Crowded Out, In Hostile Hands, In the Homes of the Cliff Dwellers, Una, Lost in the Slave Land, Smack Boys and Judge Dockett's Grandson. NO NAME.--1. When tinware is worn until the iron shows, it can be retinned by dipping it again; but the process would be too expensive, except as an experiment. It would first have to be washed in a chemical bath, and then dipped the same as tin plates. 2. Poultry raising is undoubtedly a profitable business, if followed intelligently, and is best done on an extensive scale, with the benefit of modern appliances. In Eastern cities, eggs and poultry bring very high prices during nine months of the year, and the demand is always in excess of the supply. You may gain some valuable hints on this subject by reading "Practicable and Profitable Poultry Keeping," Nos. 13 and 14, and "Nell's Chicken Farm," No. 18, Vol. 13, GOLDEN DAYS. DETECTIVE.--If you have any serious notion of being a detective, the best thing for you to do is disabuse your mind of the idea. A boy who can speak three languages and writes shorthand should secure a situation in the office of a steamship company or a large importing house which has foreign correspondents. Such talents would be thrown away in the detective business, which is not the lucrative profession you imagine. The best detectives are now in the employ of the national government or city authorities, and the supply at all times exceeds the demand. At the beginning you could not expect more than three or four dollars a day, and only during the time you were employed, and the rewards of which you have read so much would go to the agency, and not to the men who do the work.
