The Alexander Agassiz professor, any Alexander Agassiz professor, is not tied to any particular department in the Museum of Comparative Zoology and I was definitely not a member of the bird department, even though my office was on the same floor of the Museum. My major occupation, as they expected, was research and writing, but I was also expected to teach, but primarily at the graduate level. I did give, occasionally, undergraduate courses and in particular there was a period of a couple of years where I gave six major lectures in one of the big Harvard courses in anthropology in a course directed by Professor Irvin DeVor. But, otherwise, I gave mostly smaller courses to graduate students. I tried the first year there… oh the… it was in 1954… to give a course in ornithology with the particular emphasis on… on problems and field work, not one of these book courses as they gave in several other places. But for instance, we had four very interesting projects scheduled for April: one was the display of the golden-eyed duck; one was the territory staking out by redwing blackbirds, and I forget what the other two were, but they were all interesting field problems. But we could do this… only this work only on Saturdays and in that particular year, 1954, it snowed every single Saturday in April. And that convinced me that Cambridge was not the ideal place to give a field course, because by… by the time of May the semester was ending. So I never gave another course in ornithology.
