MCILHENNY, EDWARD A. _The Alligator s Life History_, Boston, 1935. OP. The alligator got farther west than is generally known--at least within reach of Laredo and Eagle Pass on the Rio Grande. McIlhenny's book treats--engagingly, intimately, and with precision--of the animal in Louisiana. Hungerers for anatomical biology are referred to _The Alligator and Its Allies_ by A. M. Reese, New York, 1915. I have more to say about McIlhenny in Chapter 30. MARCY, COLONEL R. B. _Thirty Years of Army Life on the Border_, New York, 1866. Marcy had a scientific mind and a high sense of values. He knew how to write and what he wrote remains informing and pleasant. MARTIN, HORACE T. _Castorologia, or The History and Traditions of the Canadian Beaver_, London, 1892. OP. The beaver is a beaver, whether on Hudson's Bay or the Mexican side of the Rio Grande. Much has been written on this animal, the propeller of the trappers of the West, but this famous book remains the most comprehensive on facts and the amplest in conception. The author was humorist as well as scientist. MENGER, RUDOLPH. _Texas Nature Observations and Reminiscences_, San Antonio, 1913. OP. Being of an educated German family, Dr. Menger found many things in nature more interesting than two-headed calves. MILLS, ENOS. _The Rocky Mountain Wonderland, Wild Life on the Rockies, Waiting in the Wilderness_, and other books. Some naturalists have taken exception to some observations recorded by Mills; nevertheless, he enlarges and freshens mountain life. MUIR, JOHN. _The Mountains of California, Our National Parks_, and other books. Muir, a great naturalist, had the power to convey his wise sympathies and brooded-over knowledge. MURPHY, JOHN MORTIMER. _Sporting Adventures in the Far West_, London, 1879. One of the earliest roundups of game animals of the West. NEWSOME, WILLIAM M. _The Whitetailed Deer_, New York, 1926. OP. Standard work. PALLISER, JOHN. _The Solitary Hunter; or Storting Adventures in the Prairies_, London, 1857. ROOSEVELT, THEODORE. _Outdoor Pastimes of an American Hunter_, with a chapter entitled "Books on Big Game"; _Hunting Adventures in the West; The Wilderness Hunter; Ranch Life and the Hunting Trail; A Book Lover's Holiday in the Open; The Deer Family_ (in collaboration). SEARS, PAUL B. _Deserts on the March_, University of Oklahoma Press, Norman, 1935. Dramatic picturization of the forces of nature operating in what droughts of the 1930's caused to be called "the Dust Bowl." "Drought and Wind and Man" might be another title.
