worked, while the plants were wet, the other only when the plants were 

 dry. The results confirm previous data indicating that working bean 

 plants when they are wet does not materially affect the spread of an- 

 thracnose.

In an experiment on the field control of anthracnose in which 4-4-50 

 Bordeaux mixture, Sanders' dust — 10 per cent metallic copper — and 

 sulphur were used, the protection afforded was too slight to be of any 

 practical importance. 



When infected seed was heated for the length of time necessary to 

 destroy the fungus, germination was very seriously reduced. See Table 

 XXII.

RURAL ECONOMICS 



Cheshire County Survey (State Fund) 



The study of the balance between farm production and market de- 

 mands in Cheshire County was completed by H. I. Richards and H. A. 

 Rollins during the year, and has served not only for its original purpose, 

 but as a very valuable experience in" formulating future studies. It has 

 been reported upon in detail in Bulletin 217. The Bureau of Agricultural 

 Economics, United States Department of Agriculture, co-operated in this 

 surve3^ 



State-Wide Consumption Survey (Purnell Fund) 



As a beginning in Rural Economics research work under the Purnell 

 Fund, a preliminary survey is being made by H. C. Woodworth, L. B. 

 Lincoln and H. I. Richards of the consumption of agricultural products, 

 particularly products that might be raised within the state. The object 

 of this is to survey in a general way the situation in the various market 

 centers before attempting to study any one commodity in detail. The
