Tyler, SBMNH., archeology and photography While a great deal of study remains to be made of materials collected from the Winnemucca Caves, there is little additional field excavation to be done with the exception of two caves whose entrances are so blocked with erosional debris, as to be "safe" from unauthorized pot hunters. Our relation with the various Indians of the reservation is friendly, and we have been asked by many to excavate upon the reservation, however, a few still regard us as "grave robbers", and permission from the Tribal Coun­cil to excavate on Indian lands can not be secured. In the meantime, pot hunters both Indian and white, are dissipating the scientific records for a few "arrowheads" which are probably dart points anyway. We plan to continue our studies and investigations in the Lake Lahontar area following all lines of scientific endeavor to secure as complete record of the past of this region as is possible. We will welcome the interest of specialists, particularly needed is a stufy of the rock forming organisms which created tne tufas. We wish to thank our many friends whose financial aid has made possible the expeditions, particularly the Max C. Pleischmann Foundation of Nevada; Mrs. John D. Graham; Mr. 0. H. Truman; and the Nation­al Geographic Society. We also wish to acknowledge the assistance we have received in time and labor generously donated by many, especially our scien­tific associates, previously named, arid the institutions to which they are attached, also to the trustees and the staff of the Nevada State Museum; the Santa Barbara Museum of Natural History; Mr. Carl Dentzel, director of the Southwest Museum; and to Mr. and Mrs. G. C. Rollins, owners of the mining claim on which the caves are located, who have given every cooperation to our work for the past six years. Phil C. Orr Santa Barbara, Calif. - 3 -
