 [Fries.]). The first indication of this disease is the ap- 

 pearance of yellowish spots on the leaves. These finally 



run together and turn the 

 entire leaves yellow and then

 somewhat shaded, they are 

 less liable to the disease

 in very dry locations. It is 

 reported that the Bordeaux 

 mixture and other standard 

 fungicides will entirely pre- 

 vent it.

 Plume is highly esteemed and probably the most profitable 

 variety for general marketing. It is, however, somewhat 

 subject to blight. Its stalks and leaves are white without 

 going through the blanching process, but are not of as good
