state exactly what the Army and Navy would require in the way of radio material, owing to the rapidity with which the art is advancing. Suffice it to say that it is the duty of the military experts always to have their plans ready for complete standardization of equipment, and not only ready, but in such shape and detail that in event of hostilities the manufacturers could commence work on the morrow turning out standard equipment, in quantity and without delay.
The personnel engaged in this work in the Government is exceedingly limited and now that radio has grown into such a tremendous business it would appear that the most natural procedure for obtaining standardization would be by the radio commercial interests themselves, in consultation with the Government's experts.
The Army and Navy have been in the radio business for twenty-three years, and the advent of the public into this business, with limited exceptions, has been only in the last two years. A small number of civilian and military engineers have developed their art and have handed it over to the public on a silver platter, for the profit of the radio business man and for the

happiness of the public. Not only that, but the transfer of paramount control of transoceanic radio communication from foreign to private American control was directly due to our own Navy Department.
For these and other reasons there is a duty for the radio business man, particularly, to show some measure of gratitude to his military representatives in the way of assistance in keeping a step or two in advance of any possible adversaries.
In the history of the design and development of radio equipment it will be remembered that many of the principal advances have been due to the ever-increasing demands by the Naval Service for increased range, economy, selectivity, durability and flexibility of apparatus. For years there was very little attempt at improving the standard of commercial installations on shipboard, except where naval installations paved the way. Naval specifications have each year been made more and more rigid and the requirements more difficult to comply with. The result is that the inventors and designers produced something better from something not so good, and solved the problems which appeared impossible of solution.
Follow briefly a few developments, and note the advance and standardization of certain parts of Navy equipment:
The open or straight gap, to the rotary gap, with standardization of moving parts, interchangeable for i, 2, and 5-KW sets.
The rotary to the quenched gap, with standardization of gaps, plates and washers.
The standardization on 375 meters for naval work, later 600 meters, and later still the transfer of military work into a band of wavelengths clear of the 600meter wavelength, in order that maritine commercial communication could enjoy it exclusively.
