The bureau of Plant Quarantine and Entomology of the Dept. of Agriculture, has perfected treatments that keep tiny thrips from ruining Gladiola blooms, it worked them out by subjecting the bulbs to various treatments, planting the bulbs in a large field at the experimental station at Beltsville, MD, and examining the plants as they bloomed.

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
