tions other microscopic organisms, such as the pathogenic pro- 
tozoa and the minute molds and other fungi. ‘The methods of 
cultivating these minute organisms have developed a complicated 
and highly specialized technique, which is now often utilized by 
other groups of scientists than pure bacteriologists. Tor ex- 
ample, bacteriological methods are extensively employed for the 
cultivation of organisms which produce disease among. plants, 
for growing molds and other fungi in studies on fermentative 
or other changes in cheese, milk, etc., as well as in the growing 
of yeasts for the brewing industries. ‘There has even sprung 
up a special division of plant bacteriology, as a rapidly increas- 
ing number of diseases of plants have been found to be caused 
by bacterial organisms; and another of soil bacteriology, to 
study the wonderfully important bacterial activities in soils. 
In recent years, there has arisen a fertile field for applying 
botanical knowledge in the study of the micro-organisms of 
drinking water. By a microscopic examination, the cause of 
evil odors or tastes in water is often readily traced to plant 
causes, thus suggesting at once the proper remedy. inally, 
botanical science touches biochemistry at many points. The 
biochemist analyzes plant products of all sorts, including foods, 
yoisons and drugs. 
he foregoing brief analysis, showing the fundamental re- 
lation of botany to agriculture and other applied sciences, sug- 
gests many possible lines of useful work for the Botanic Garden. 
Such work, if emphasized, may readily be made very useful to 
the community directly served by the Garden, as well as to the 
country at large. Not alone along the lines of research and ex- 
ploration in problems of special interest, and by acting in con- 
sultation with citizens seeking information and advice, but also 
in teaching many of these subjects, the staff of the Garden may 
render valuable service to the community. Besides the elemen- 
tary instruction to grammar school and high school pupils, and 
the more advanced instruction to teachers and others now 
planned, the Garden would undoubtedly serve a useful purpose 
in offering courses in gardening or in agricultural botany. Work 
of this sort is in close harmony with the purposes for which the 
Garden was established, as stated in the original Act of the State
