T. P.—The first and second volumes of Golden Days, being out of print, are not for sale at this office, and naturally command a premium when sold by other parties. Bound volumes are usually quoted at ten dollars, and higher prices may have been given. They may be had, however, occasionally through the medium of our exchange columns.

A Subscriber.—1. The U.S. navy now has 116 vessels of all kinds, of which 44 are building or not in commission. 2. The greatest war ship of the English navy, and also the greatest in the world, is the Royal Sovereign, 380 feet in length, 75 feet in breadth, and of a displacement of 14,150 tons. The armament consists of four 13½-inch guns, ten 6-inch quick-firing guns, and twenty-five 6-pounder and 3-pounder machine guns.

Don’t Know.—Upon meeting a young married woman, upon her return from her wedding journey, it would be proper to congratulate her and wish her happiness in her new relation; but, if you had not previously known her in a single state, a simple acknowledgment of the introduction is all that would be necessary.

Archy Tect.—A knowledge of geometry is essential to a successful architect; in fact, he should be expert in all branches of mathematics, as well as a good draughtsman. See answer to “Arch-I-Tect,” in No. 42, Vol. 13, for your other questions, to which it is only necessary to add that architects are paid according to contract only.

J. B. McF.—A tun is a certain measure for liquids, as for wine, and its capacity equals two pipes, or four hogsheads, or 252 gallons. Being a measure, a tun may be made of any shape, so that the capacity is neither increased or diminished. Any school arithmetic treats of this subject under the head of “measures.”

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.
