Bob Folk sports a new Tahitian shirt (and a beard) — souve nirs of his recent trip !
Sam Ellison and Graduate Student Luis Ardila do some "checking" in Sam's laboratory which adjoins his office.
in micropaleontology, general geology, the geology of petro leum and geology for high school teachers. Next fall he will again teach a special small section of general geology for stu dents with superior scientific background. This summer Sam taught the nine-weeks Earth Science Summer Institute course and "time left over" was spent in writing papers. His "Third Supplement to Conodont Bibliography and Index" appeared in the April 1967 Texas Journal of Science.
Peter Flawn, Bill Fisher and Pete Rodda all took active parts in teaching this year in addition to their work for the Bureau of Economic Geology, and Virgil Barnes continues to to work closely with our graduate students. The activities of these men are reviewed more fully in the section of this News letter devoted to the Bureau.
Bob Folk left the campus in mid- June (right after moving into the new building) with his graduate student, Jim Dob kins, for Tahiti to do research on shape development which was supported by funds from the Geology Foundation. Unfortunately, after having been in Tahiti for only a few weeks, he came down with pneumonia and had to return to Austin. His recovery was a slow process, which made him un happy since he had planned to spend the rest of the summer working "furiously" on the Simpson Desert sands of Australia and finish his paper on bird urine. But at least he got to spend some time reading lots of desert and red-bed literature !
During the school year, Bob taught courses in sedimen tation, carbonate petrology and the petrography of sandstones. He also served as one of the instructors of the sedimentation graduate courses offered by the University at Midland last fall. He co-authored a paper, "Portrait of P. D. Krynine," which appeared in the Journal of Sedimentary Petrology, and has one in press in the Journal of Geology, "Geomorphology of Sand Cays of Alacran Reef." Last November, he presented a paper, "Sands of the Simpson Desert, N. Territory, Aus tralia," at GSA, and as soon as the meeting was over he trav
eled to Boulder, Colorado to give a lecture. This was at the first annual convention of the Friends of the Microscope So ciety. He was an AGI Visiting Scientist, lecturing at the Uni versity of Mississippi and Mississippi State College. Bob also found time to add a Chinese pagoda to the top of his house and he is still avidly gathering foreign coins and stamps for his collection (this last is a hint for our exes ! ) .
Claude Horton, who holds a joint appointment as Professor of Physics and Geology, again taught the graduate course in geophysics as well as remaining active in the Physics Depart ment. Claude's prime research interest is in acoustic waves and two papers on this research were published during the year in the Journal of the Acoustical Society of America. Another paper, "The Electrical Conductivity of the Earth's Mantle," appeared in Magnetism and the Cosmos. He is chairman of the Visiting Scientific Committees for Woods Hole (Massa chusetts) Oceanographic Institution. He is a member of the Acoustical Society of America and he attended its annual meeting in New York City in April. Claude's summer was spent in Austin revising the manuscript of his book, tenta tively titled Signal Processing of Acoustic Waves.
Earl Ingerson was awarded two research grants during the year, one from the University Research Institute for hydro thermal research and the other from NSF for the study of age and formation of caliche. He taught general geology and the graduate course in geochemistry this year and next year will teach a course in structural petrology. In the fall he went to Mexico to check area 3 around Zacatecas and Durango for thesis and conference courses, returning in January to con duct geological field investigations in the area southwest of Torreon and to visit phosphate deposits at Conception de Oro. In December he made a tektite search in Grimes County and in March went to Karnes County to check uranium deposits.
As President of the International Association of Geo chemistry and Cosmochemistry, he presented the opening ad
