their unwelcome attentions to many other plants the trouble 

 might become a real one, but up to the present it is nothing. 

 Of course, the man who has mould, or yellowing, or who 

 suspects streak will adopt preventive measures, and the 

 most effectual is to change the position of the plants, putting 

 them as far away from the infested area as possible in the 

 following season. He will supplement this by generous 

 dressings of lime, spreading it on the surface to a depth of 

 half an inch or thereabouts, and after a week or ten days 

 pricking it into the ground. This will destroy the spores 

 of any fungi with which it may happen to come in contact, 

 and will at the same time sweeten and immensely improve 

 the fertility of the soil. The genuine streak, it may be of 

 interest to note, runs in clearly defined, dark lines up the 

 stems, but at a certain stage of mould the resemblance of 

 this disease is very close.
