by John Edwin Hogg, Lieut., U.S.N.R. An amazing scientific workshop afloat â€”that is the peace-time function of Uncle Sam's Navy. The discoveries made by navy engineers and scientists have been responsible for the creation of vast new industries, from which you benefit in many ways, as told here. TO THE average person, perhaps, the American navy is a tremendous engine of destruction draining the Federal treasury of approximately $350,000,000 every year, and serving no useful purpose to the nation except in time of 'war. Nothing could be farther from the truth. The American navy in times of peace is a great progressive institution that extends its ramifications into many fieldsâ€”scientific, mechanical, social, and diplomatic.

Probable lines of development of tomorrow's car are here authoritatively presented. PROFILES of automobiles, like profiles of women's hats, have a habit of changing swiftly and drastically in response to the whims of fashion.
EVEN the most rabid enthusiast cannot defend the weakness of the hydrogen-fill dirigible. Death and destruction lurk in every cubic foot of it. Human ingenuity has failed to devise a means of making it safe and the prospect of riding the air with 2,000,000 cubic feet of a violent explosive over one's head is not alluring, at least to those who have had laboratory experience with the energetic hydrogen atom.
VISUALIZE two million straining horses lashed to a load that would be one-eighth the weight of Mount McKinley and you will have some idea of the tremendous power that will be generated in the low-grade coal districts by the super-power stations of the near future.
