FUNGI AND 
HUMAN AFFAIRS 
By W. A. McCUBBIN 
Pennsylvania Bureau of Plant Industry 
eee book makes clear the vitally important part 
played by fungi and bacteria in modern life. It is 
written so simply and non-technically that the student 
who has had little or no scientific training can obtain 
from it a useful knowledge of bacteria and fungi as 
related to our everyday affairs. 
The general nature of fungi and bacteria is brought out, 
and by means of photographs and original diagrams and 
drawings, the reality of these small organisms and their 
place in the realm of nature is impressed upon the stu- 
dent. With this background, the subjects of wood rots 
and food preservation are taken up. Finally, the réle 
of fungi and bacteria in producing plant diseases is dealt 
with fully but simply. Numerous plant diseases are con- 
sidered separately, and the ways in which they are 
spread, how they are restricted, and the methods of con- 
trolling them are explained. 
The importance of the subject matter merits its study by 
students in agricultural schools and by the gardener or 
farmer, while the simplicity of the treatment makes the 
book suitable for any nature study or biology course in 
upper elementary grades or in high school.
