554 Rrrort oF THE HorRTICULTURIST OF THE 
the anthracnose. At the close of the season Mr. J. W. Stepfield, 
of Horseheads, N. Y., in whose field these things were noticed, 
reported that the anther enol did not appear on the Mexican 
tree beans at all during the season. 
This blight affects the foliage and pods as before stated and 
also affects the beans within the pods. Some of the pods fail to 
ripen while others which mature, produce beans that are dis- 
colored by the disease or wrinkled or disfigured with rough spots. 
It is possible that the blight may be communicated to the crop 
of the following season in the seed, as is probably the case with 
the blight of lima beans, and therefore all blemished seed should 
be rejected when planted. Whether this blight on the common 
beans, Phaseolus vulgaris, L. is identical with the one next’ 
described as attacking Lima beans is a question not yet decided. 
The subject is under investigation and the results may be noted 
in a subsequent report. 
Blight of Lima Beans. 
A bacterial disease occurs in Lima beans and forms definite 
characteristic spots on pods and leaves, especially in its earlier 
stages. These spots differ in appearance from those formed by 
the blight on Phaseolus vulgaris but whether the difference in 
appearance is due to the influence of the different host plants, 
and the blight in both cases is due to the same germ has not been > 
decided. Probably the two diseases are distinct. Figure 8, from 
a photograph, shows the characteristic spots on leaves and pods 
of Lima beans. So far as noticed,. these spots are never black, 
but often have a reddish purple border inclosing an area of a 

light red color. On the leaves the spots gradually increase in _ 
size and develop a straw colored center of dead tissue. Sometimes 
the centers of the spots on the pods also become straw colered. 
In the Station garden this blight did considerable damage, and 
on October tenth it was almost impossible to find a Lima pod free 
from the disease. 
A study of the blight has been made in the laboratory in the 
fellowing way. The germ was first isolated by means -ef plate 
cultures. It was then transferred to various nutrient media
