INTRODUCTION. 
The world-wide importance of bunt, or stinking smut, as a factor 
influencing wheat production, its great antiquity as a cereal disease, 
and the vast amount of published matter relating to it, much of 
it not generally accessible, are facts seeming to justify the publica- 
tion of this bulletin. 
In the preparation of the subject matter it has been considered 
advantageous to present the data in the following historical periods: 
(1) The pre-Tillet period (500 B. C. to 1755 A. D.). 
(2) The Tillet-to-Kiihn period (1755-1870). 
(3) The Kiihn or moderu period (1870 to date). 
_ The first of these periods is characterized by the almost complete 
‘absence of information based on an experimental investigation 
of the problem and by the preponderance of inferences and ¢ -onclusions 
derived through hearsay and speculation. The second, or Tillet- 
-to-Kihn period, marks the beginning of bunt investigations by 
‘the experimental method. During this period the causal relation- 
_ ?The manuscript for this bulletin was submitted for publication August 6, 1923. 
? The investigations on the physiology and control of bunt, or stinking smut, of wheat, were conducted 
by the Office of Cereal Investigations, Bureau of Plant Industry, United States Depar tment of Agriculture, 
hn cooperation with the Washington Agricultural Experiment Station.
