George T. Moore Gives a Valuable Article on Bacteria 
and the Nitrogen Problem, in the Yearbook of the United States 
Department of Agriculture 1902 1333-42, illustrated with 6 full- 
page plates. Investigation of the nitrogen-fixing bacteria has 
been carried on at the Bureau of Plant Industry in the laboratory 
of plant Physiology. It has been found ‘'that by gradually re¬ 
ducing the amount of Nitrogen in the culture medium it is pos¬ 
sible to greatly increase the nitrogen-fixing power of the germs, 
and that by proper manipulation their activity may be increased 
from five to ten times that which usually occurs in nature.”
