HALL, E. RAYMOND. _Mammals of Nevada_, University of California Press, Berkeley and Los Angeles, 1946. So far as my knowledge goes, this is the only respect-worthy book extant pertaining to the state whose economy is based on fees from divorces and gambling and whose best-known citizen is Senator Pat McCarran. HARTMAN, CARL G. _Possum_, University of Texas Press, Austin, 1952. This richly illustrated book comprehends everything pertaining to the subject from prehistoric marsupium to baking with sweet potatoes in a Negro cabin. It is the outcome of a lifetime's scientific investigation not only of possums but of libraries and popular talk. Thus, in addition to its biographical and natural history aspects, it is a study in the evolution of man's knowledge about one of the world's folkiest creatures. {illust. caption = Charles M. Russell, in _The Blazed Trail of the Old Frontier_ by Agnes C. Laut (1926)} HORNADAY, WILLIAM T. _Camp Fires on Desert and Lava_, London, n.d. OP. Dr. Hornaday, who died in 1937, was the first director of the New York Zoological Park. He was a great conservationist and an authority on the wild life of America. HUDSON, W. H. _The Naturalist in La Plata_, New York, 1892. Not about the Southwest or even North America, but Hudson's chapters on "The Puma," "Some Curious Animal Weapons," "The Mephitic Skunk," "Humming Birds," "The Strange Instincts of Cattle," "Horse and Man," etc. come home to the Southwest. Few writers tend to make readers so aware; no other has written so delightfully of the lands of grass. INGERSOLL, ERNEST. _Wild Neighbors_, New York, 1897. OP. A superior work. Chapter II, "The Father of Game," is on the cougar; Chapter IV, "The Hound of the Plains," is on the coyote; there is an excellent essay on the badger. Each chapter is provided with a list of books affording more extended treatment of the subject. JAEGER, EDMUND C. _Denizens of the Desert_, Boston, 1922. OP. "Don Coyote," the roadrunner, and other characteristic animals. _Our Desert Neighbors_, Stanford University Press, California, 1950. LOCKE, LUCIE H. _Naturally Yours, Texas_, Naylor, San Antonio, 1949. Charm must never be discounted; it is far rarer than facts, and often does more to lead to truth. This slight book is in verse and drawings, type integrated with delectable black-and-white representations of the prairie dog, armadillo, sanderling, mesquite, whirlwind, sand dune, mirage, and dozens of other natural phenomena. The only other book in this list to which it is akin is Eve Ganson's _Desert Mavericks_. LUMHOLTZ, CARL. _Unknown Mexico_, New York, 1902. Nearly anything about animals as well as about Indians and mountains of Mexico may be found in this extraordinary two-volume work. OP.
