POCKET NATURAL HISTORY 



Natural history includes six great sciences : 

 Astronomy — The story of the universe. 

 Geology — The story of the earth. ^^ 



Paleontology — The story of ancient life. ^^ 



Botany — The story of plants, 

 '/.oology — The story of animals. 

 Anthropology — The story of man. 



The function of the Museum is to gather the mater- ^^ 

 ials of these sciences, to study their hidden meaning, 

 to exhibit them, and, most important, to interpret 

 them for the benefit of all the people. 



Pocket Natural History is the title of a series of 

 popular interpretations of nature, of which "Trees of 

 Ohio" is the first number. Each of the natural history 

 sciences will furnish many interesting subjects. Simple 

 guides to identification will be followed by intimate 

 stories of the history of the earth and the life upon it. 

 The Museum hopes to issue two numbers on each 

 science each year. 



The form of these publications is designed for 4fe 

 simplicity and convenience. Each issue is accompanied 

 by a jacket for protection in the pocket. It is also 

 punched to fit standard loose-leaf note books obtain- 

 able from any dealer. Most books are infrequently 

 consulted because they are not immediately at hand £k 

 when the need for them arises. These slip conveniently ^m 

 into the pocket for ready reference in the field or 

 for reading in leisure moments. 



It is our hope that the simplicity and comprehen- 

 siveness of these little publications may bring new ^fc 

 interests and a wider and deeper appreciation of na- 

 ture into many lives. 



Paul M. Rea, Director.
