About six months ago, four officers of the Illinois State Veterinary Medical Association requested a conference with some of the officials of the Illinois Agricultural Association, which is the state farm bureau organization. A story on successful swine raising had appeared in the Illinois Agricultural Association's publication the Record. One of the pictures published with the story showed a group of farmers vaccinating their own pigs. The veterinarians felt, that, in addition to this picture, some of the advertising the Farm Bureau Serum Association had been using in the Record was objectionable.
