Vernon Orlando Bailey (1864-1942) was a naturalist who collected for the Division of Economic Ornithology and Mammalogy of the United States Department of Agriculture (in 1896 the name was changed to the Bureau of Biological Survey) under Clinton Hart Merriam. He joined the Bureau in 1887, and eventually became chief field naturalist in 1890, remaining with the Biological Survey until his retirement in 1933. Bailey's chief biological interest was the study of the life history and distribution of mammals. During his career with the Biological Survey, he made field investigations throughout the United States, Canada, and Mexico, including intensive biologicalsurveys of Texas, New Mexico, North Dakota, and Oregon.

The weather has been clear and pleasant tho (sic) cold.
