Couimissioner of Agriculture, Albany: 



Sir: — For several years, serious diseases have threatened the great 

 bean industry of New York. These diseases are not yet thoroughly 

 tniderstood, but enough is known about them to warrant the preparation 

 of a brief popular bulletin of advice. It is hoped that this bulletin will 

 call out the expressions of bean-growers who have had experience that will 

 be useful to others; and this Experiment Station will continue its 

 investigations. 



Following is an outline of the subjects treated in this bulletin:
