In preparing job contracts for individual instruction, it was found that it would be almost impossible for any High School Instructor to secure enough reference material from other states to supply class needs. These contracts require information from practically every state if they are satisfactorily fulfilled.
It is the intention of the writer that this write-up on Swine should accompany the job contracts. The write-ups contain nearly all of the information that will be required by the average student. If additional information is desired, it can be selected from the references given at the end of each chapter.
