"Stockmen who graze cattle on the mountain ranges of the western United States suffer heavy loses from larkspur poisoning. Careful and long-continued investigation under range conditions has shown clearly under what conditions these deaths occur and has shown also that by sufficient care most of the losses can be avoided. This bulletin, in a brief form, gives the facts and measures which should be taken to reduce the losses. Bulletin 365 of the United States Department of Agriculture, a professional paper, treats the subject in a more detailed and technical manner."--Page [2]
