The African pictures were taken while I was employed as a lecturer in biology at the University of Botswana, Lesotho, and Swaziland from 1970 to 1975. I spent the academic year from 1970-71 in Roma, Lesotho and then moved to Luyengo, Swaziland in July, 1971 and started the biology department at a new satellite 2-year campus of the University. The pictures were taken on my travels in Lesotho, and in South Africa when I traveled to and from meetings in Lesotho and Botswana. In 1975 I moved on to Oregon State University where I was a member of the Department of Microbiology and taught and did research in virology.
