Government cartographer develops new process for making relief maps. Washington, D.C., Jan. 13. Through a process just perfected by John Braund, Cartographer for the U.S. Coast and Geodetic Survey, relief maps can now be made showing all the details of topography in a form true to nature and which can be quickly understood and accurately read by even the untrained map reader. Instead of compressed paper or cardboard, Braund uses thin metal on which he has printed the map desired. He then hammers out the typography with a special electric hammer he has designed. Braund says this new method has proved more speedier, efficient, and costs less to make than maps, 1/13/39
