Imperishable insects created by scientists. Washington, D.C. June 18. William R. Walton, Senior Entomologist of the Division of Cereal and Forage Insects, U.S. Department of Agriculture, whose unique hobby is the making of metal casts of all sorts of insects from the tiniest Scarab to the enormous six-inch Goliath Beetle, which feeds on the tropical vegetation of New Guinea. In his distinctly original work Mr. Walton uses the Galvano-Plasty method of metal coating, which he set about developing over 30 years ago. This is an electro-mechanical process similar to the electrotype process used in making newspaper cuts. 6/18/37
