ence meeting in Austin; in March he went to the Houston meeting of AAPG. Dr. Maxwell continues to give talks on geology to science classes in the Austin Public Schools and to serve as a counse lor and committee member of the Boy Scouts of America Troop 11. He is a member of the Board of Directors for the Highland Lakes area of the Capitol Area Council of BSA and also serves as a member of the Board of the Central Christian Church in Austin. Bill Fisher during the year brought to completion or near completion several of his projects and began work on a new one. His report on Texas lignites is now in press; his study, with Pete Rodda and John Dietrich, of the evolutionary trends of Athleta petrosa Conrad is in manuscript and now being edited; and his investigation, with Pete Rodda, of Comanchean high-calcium limestones and silica sands is al most finished. He is currently directing the Bureau's study of the mineral raw materials of 42 east Texas counties, which is scheduled for completion by July 1964. A paper on sedi mentary patterns in Eocene rocks of the northern Gulf Coast is to be published this year in The Kansas Geological Sur vey's Symposium on Cyclic Sedimentation. Bill attended the annual meetings of the Gulf Coast Associ ation of Geological Societies in New Orleans, The Geological Society of America in Houston, the Texas Academy of Sci ence in Austin, and the AAPG .meeting in Houston. At the GSA meeting, he presented a paper on formation boundaries of the western Grand Canyon area of Arizona. Don Kohls during the year completed his study of the chemistry of Texas coal and lignite, which was published last October as the Bureau's Mineral Resource Circular No. 43, "Reconnaissance of Trace Elements in Texas Coal and Lig nite." He is continuing his investigation of the geology and mineralogy of the Wilcox sand-kaolin belt that crops out be tween the Brazos and Trinity Rivers in east-central Texas. Don attended the Houston meeting of The Geological So ciety of America in November and the Dallas meeting of AIMME in February. Last April, he was the leader of the northeast-central Texas portion of a clay studies field trip that was sponsored by the universities of Missouri, Oklahoma, and Texas. Dr. and Mrs. Kohls are celebrating their first wedding an niversary this summer as the proud parents of a brand-new baby daughter, Nancy Ann. Phil Morey, who is the geologist in charge of the Bureau's extensive Well Sample and Core Library, has prepared a new index of well samples and cores. Phil also has been busy processing the very welcome gifts of well samples and electric logs from Shell Oil Company and the shallow cores from Trinity Testing Laboratories, Inc., which were received by the Bureau during the year. Don Owen, one of the Bureau's newer staff members, is now Dr. Owen. He received his Ph.D. degree from The University of Kansas on June 3. Don is currently working on the Texas Geologic Atlas Proj ect and is engaged in geologic mapping of portions of the Van
Horn-El Paso sheet, including the San Antonio Mountain and Tepee Butte quadrangles, and in photogeologic mapping of alluvial deposits on the Tyler sheet. During the year, he also continued his study of the phos phate nodule beds that occur in Gulfian and Midway strata of the Texas Gulf Coastal Plain. Last fall, Don completed a short course in FORTRAN computer programming at UT, and, at the GSA meeting in Houston, he presented a paper entitled "Gradational Boundaries of the Dakota Sandstone in the Southern San Juan Basin, New Mexico." Pete Rodda, during the spring semester, not only brought several of his research projects to a successful conclusion but also taught a course in invertebrate paleontology. His re search study, with Bill Fisher and John Dietrich, of the evolu tionary trends of Athlea petrosa Conrad is now in manuscript, and his investigation, with Bill Fisher, of Comanchean high calcium limestones will soon undergo critical review. He is now preparing a catalog of type specimens in Bureau paleon tological collections and is working on the stratigraphy of the Washita Group in Texas. Last fall, Pete attended the meeting of the Gulf Coast As sociation of Geological Societies in New Orleans where he gave a paper about fused rocks in the Jackson Group. At the GSA meeting in Houston, he presented a paper, co-authored by Bill Fisher, on fossil barnacles. This paper was later pub lished in the December issue of the Texas Journal of Science. Last March, he attended the AAPG meeting in Houston. Dan Schofield, who is chemist in charge of the Bureau's Mineral Studies Laboratory at Balcones Research Center, has been busy during the year providing quantitative analytical data for Bureau staff projects, including the high-calcium limestone project and the east Texas mineral resources in vestigation. His study, with Virgil Barnes, of possible com mercial industrial sand deposits in central Texas Cambrian rocks is near completion. The new quarters of the Laboratory at Balcones Research Center, which Mr. Schofield helped design, are now com pleted. Dan is also supervising installation of equipment and soon will set up operations in this new facility. John Dietrich is mapping and correlating volcanic rocks northwestward from Big Bend National Park into the Bofecil los Mountains of southern Presidio County. In addition, he is completing work on his doctoral dissertation mapping prob lem in the Ocotillo, Ochoa, and Presidio quadrangles of Pre sidio County. During the year John continued programming the Model 1604 digital computer at UT's Computation Center to process data collected by Pete Rodda and Bill Fisher for the Athleta petrosa project, a study of the evolutionary trends of an Eo cene gastropod. Last fall, he attended a short course at UT on computer applications in geology. He has expanded the basic statistical program written during this short course to produce a flexible computer program that can be used to process varied data. Rosette Girard was active in the public service work of the Bureau by providing mineral information in reply to queries
