The State, through these agencies, can well afford to produce the serum free of cost as a means of conserving resources which are now lost to the State to the amount of millions of dollars. The production of a reliable serum is a necessity for use in official work in suppressing this disease, and cannot, with safety, be entrusted to private concerns or to men who have not had proper training in laboratory and surgical technic, and a special training in this particular work; as well as a good knowledge of the path- ology of hog cholera and other swine diseases.
