(1) LIEUT.—COLONEL H. HOERNES has, under the title given above, produced a very readable popular hand book, and its low price and handy size should find it a ready market. Its chief value is as an historical record, the section dealing with dirigibles being particularly useful and giving a mass of important information in a small space. As may be expected from one whose name is well known as an authority on lifting-screws, the author declares emphatically for the helicopter as the machine of the future, and says: “In my opinion at least, the lifting-screw machine, or helicopter, forms an advance on every other type of flying-machine.” The reasons for this statement are given as its capabilities for vertical rise, its lightness, strength, and ease in landing, its safety, trustworthiness, and ease in control.
