Chats With the Editor RADIO school for farmers and others is something new in the way of carrying instruction to large numbers of people. It is to be inaugurated by the government beginning in October and the method by which it will be accomplished is described in this issue by Sam Pickard, recently appointed head of the radio section of the U. S. Department of Agriculture. Mr. Pickard writes the first announcement of the National Radio Farm School while other experts of the department will give our readers a series of articles covering the various activities of the school and cite instances where profitable advantage has been taken of the course. Amateurs, (or hams as they are known to each other) , will join us in congratulating Armstrong Perry on his exposition of the life of an amateur. There have been many stories written of the ham but we believe Mr. Perry's tops the list. Naval maneuvers are always interesting to Americans, especially when it is the U. S. Naval maneuvers to which reference is made. The part that radio is playing in the present war tactics is portrayed by G. K. Spencer and liberally illustrated with photographs. You again have evidence of the fact America has led the field in its utilization of radio, this time for use as a military weapon. Power amplification and power supply devices are now capturing the public attention to a degree never considered possible. A full line of power supply devices will be found in the blueprint section as well as other sections of next month's issue, written so even the inexperienced may read and build. Editor of RADIO AGE.
