THE COLLECTING AND STUDYING OF ANIMALS AND 
PLANTS 
In taking up the study of any part of natural history, the first 
thing a person wishes to know is how to collect and preserve speci- 
mens, and where to get apparatus for work. Natural history is i^-i- 
marily an obsei'vation study m the field and collection room. The 
first thing to know is how to find specimens in the field, the next is 
to study their structure and classification in the cabinet, then continu- 
ously and intensively to study further in the field their ecology. 
The U. S. National Museum publishes a series of pamphlets 
which are necessary to anyone taking up natural history study. They 
may be obtained free by writing to the Secretary, Smithsonian Insti- 
tution, Washington, D. C.
