June 8, 1966 – Mr. Harry E. Chrisman Maverick Publications Incorporated 10245 W. 14th Avenue Denver, CO 80215 Dear Mr. Chrisman: Your request for photographic material to be used in a magazine article on locoweed has been referred to this office for reply. The Department of Agriculture published in 1919 (and revised in 1936) a Farmers’ Bulletin No. 1054, “Locoweed Disease”. This bulletin used a photgraph of a locoed hirse and photographs of typical symptoms of locoism. The wooly or prple loco plant, Astragalus mollissimus, is one of these seven, but the other species, due to their toxicity and their regional occurrence, are probably just as significant hazards for livestock in the West. Your request for photographs has been referred to the Department of Agriculture’s Photographic Division with the suggestion that they send you a print of the horse photograph shown in Farmers’ Bulletin No. 1054, and also a print of each of four of the loco plants which have been reported to be especially toxic for horses. There is a Texas Agricultural Experiment Station Bulletin No. 456, “Locoism in Domestic Animals”, by F. P. Mathews, which includes photographs of locoed animals. You may wish to see this bulletin as well as some of the following publications pertaining to the same subject: (1) Mathews, F. P. The Poisonous Astragali. The Veterinary Student, Fall 1942. pp. 26-30. Iowa State College, Ams, Iowa. (2) Fraps, G. S. and E. C. Carlyle. Locoine, the Poisonous Principle of Locoweed. Exp. Sta. Bull. 537, 1936. Texas A & M College, College Station, Texas (3) Smith and Jones, Veterinary Pathology. Lea and Febiger. 1957. see page 589. Sincerely yours, I. P. Earle Biochemist
