The question has been asked whether bulbs at- 

 tacked by the Vermicularia can safely be used for seed 

 onions, and it may be said that this can be done with 

 perfect safety, provided that the fungus has not at- 

 tacked them sufficiently to have induced rotting; since 

 as a rule the surface layers only are affected, the bulb 

 being- otherwise sound. No infection of the seed or 

 seed stalks is to be feared; but the old bulb will be 

 likely to harbor the fungus during the summer, and 

 communicate it to market onions if planted near them.
