To me a circus is full of glamour and intrigue and a source of never ending mystery and fascination. Even the people that comprise the circus family are a different and peculiar lot compared to the rest of us humans. Circus people are individualists in the extreme and are worth your study, for they will give you a new and very interesting sidelight on the human race. My service as a circus veterinarian covers a period of 11 years, dating from 1919 to 1930, and was a very enjoyable and interesting experience.
