ANSWERS TO CORRESPONDENTS. STUDY AND STUDIO. BEATRICE M. PARAGREEN.—We do not know the book to which you refer. There is a book, _Chapters on the Art of Thinking_, by James Hinton (published at 8s. 6d.); and another, _Three Introductory Lectures on the Science of Thought_, by Professor Max Müller (published at 2s. 6d.), which might help you. If you specially want the volume you name, write to the publisher or author of the book where it is recommended, asking for details. EURYDICE.—Note the error in spelling your pseudonym. The story of Orpheus is as follows:—Orpheus, a mythical personage, was supposed to live before the time of Homer. Presented with the lyre by Apollo, and taught to use it by the Muses, he could attract all living creatures, and even trees and stones, by his enchanting music. When his wife, Eurydice, was stung by a serpent and died, he followed her into the abode of Hades, and by the charm of his lyre won her back from the king of the regions of the dead. One condition only was attached to this favour—that Orpheus should not look upon his recovered wife until they had arrived at the upper world; but just at the last moment he did look back, and she was caught away into the infernal regions once more. The story is often mentioned in classic literature, and is to be found in any classical or mythological dictionary. A charming poem upon the legend, by one of our readers, first sent for criticism in this column, appeared in THE GIRL’S OWN PAPER for December, 1898. K. S. J.—We should think that your copy of _The Mercurie_, of July 23rd, 1588, if genuine, is certainly valuable. Write to the authorities of the British Museum, London. A MAY BLOSSOM.—We should advise you to write to the Secretary, Board of Technical Education, St. Martin’s Lane, London, W.C. He will answer all your questions. We fancy the only way to obtain a situation as technical teacher of any subject, is to watch for vacancies and apply for them as they occur. PRIMROSE.—1. Write to the Secretary of the Church Missionary Society, Salisbury Square, London, E.C., inquiring for the hymn in question.—2. We do not think it is customary to have a cake and a new wedding-ring at a silver wedding. At any rate we have never heard of the practice in London. HOPEFUL.—The best course would be for you to allow the young girl, who has so good a voice, to attend for a course of training at the Royal Academy of Music, Royal College of Music, Guildhall School of Music, or Trinity College, London. For terms see Answers to Correspondents in THE GIRL’S OWN PAPER for May, etc. No correspondence with a professional singer would be of much use in the way of tuition. If you had given your address, our advice might have been more practical. Good lessons are all-important.
