And so I spent a summer, sort of final summer in my college time checking all of the references in their book. And this involved, among other things, going through the Audubon Folio and the museum had original Audubons. It had Catesby, et cetera. So I had a wonderful experience documenting, species by species, the original references, et cetera, on those species. So it was a delightful occasion on the one hand, but sort of a sad one, knowing that my mentor was in pretty ill health. One of his brothers was teaching at the College of Charleston in Greek and Latin. The other was a neurosurgeon, but would not touch his brother in respect to his ailment. He later recovered fully and became even more ardent conservationist than he was.
