Mention Technical World Magazine Salvation! How I was saved by Mrs. Eddy and Christian Science By CHARLES KLEIN Charles Klein, whom everyone knows as the playwright-author of “The Music Master," which has captivated every theatre-goer in the country, has contributed to February Cosmopolitan an article on his own experience with Christian Science. He states how he was saved by the doctrine of Mrs. Eddy, the founder of this cult which has spread over the length and breadth of this land-even the world-in but a few years. Mr. Klein gives his impartial opinion of Christian Science based on experience. Coming in the midst of a season of so-called exposés of Christian Science, his article is indeed refreshing and has in it the tone of an authoritative statement. Damnation! The Pool-Room Vampire and its Money-Mad Victims By JOSIAH FLYNT C. In this article, Josiah Flynt, best informed of all writers on men and matters of the “under-world," tells of a traffic that has wrecked more homes than Wall Street, that has claimed more victims than the bucket shops, that is conducted by a cluster of trusts more vicious, more rapacious, more absolute than the Standard Oil Company. T This is the criminal enterprise known in common parlance as “playing the ponies"-gambling at the race-tracks and in pool rooms, where the game is in the hand of a comparatively few crooks of varying degrees of assumed respectability. The pool room has not the protection of the statute books, but it has the protection of “the man higher up,” and has infested nearly every good-sized town and city in the country. February Cosmopolitan 1789 Broadway, New York Mention Technical World Magazine This story is one which is sure to make a big sensation; there will be nothing approaching it in interest in the magazine world in 1907. Competent critics who have read it in manuscript, both here and in England, have pronounced it to be one of the greatest novels published in the last twenty years. Mr. Vachellis neither unknown nor inexperienced as a novelist. In Great Britain the sales of his books place him among the first five English writers of fiction; in this respect he takes rank with Mrs. Humphry Ward and Mary Cholmondeley. . "Her Son" is a story of extraordinary originality, immense dramatic power and intense human interest. It is filled with situations which bring to a climax the conflicts of human emotions. The tone and atmosphere of the tale are pure and elevating because of the character of the heroine; it is powerful and invigorating because of the masculine strength of the hero. It is told with a literary finish and skill equal to that of Edith Wharton or Robert Hichens.
