Excerpt from The Fauna of Rancho La Brea, Vol. 1: Occurrence In the course of the work Dr. Ralph Arnold, Mr. W. W. Orcutt, and Mr. A. E. Preston have greatly assisted in the interpretation of the geologic rela tions of the asphalt beds. During the last year's work Mr. L. H. Miller assisted in every way possible in the direction of the excavations, and has contributed a considerable number of valuable specimens to the University. Mr. E. L. Furlong brought together some of the most valuable collections in the first two years of work, and also prepared and mounted many of the specimens. Mr. E. J. Fischer efficiently carried on the work of collection for approximately a year, and has presented several specimens obtained by him before his connection with the University. Dr. C. O. Esterly of Occidental College and Dr. F. C. Clark of the Pacific College of Osteopathy have both assisted very generously through loan and gift to the University of valuable specimens needed for study.
