can establish a reputation for our seed with respect to quality, purity 
and freedom from disease. 
Now is the time to do this, before our fields become generally 
infected, and while the prevalence of disease is so slight that it can 
be controlled for the most part by the meansi that we have at our dis¬ 
posal. 
For the present consideration, we shall confine the discussion of 
bean diseases to those which have been observed to occur in the State 
during the last two years, and which, if neglected, may prove a ser¬ 
ious menace to the industry.
