caying vegetable matter or care should be used that the matter 

 is thoroughly decomposed. Fresh sand is said to be the best for 

 small seedlings. 



Soil in which plants have once been diseased should be dis- 

 carded if it cannot be sterilized by steam heat for several hours. 

 Fresh soil free from vegetable matter should be introduced. 



Water the soil thoroughly but not to saturation and do not 

 water oftener than actually needed. 



Keep the houses well lighted, well supplied with fresh air. Do 

 not have high temperatures, keep as even a temperature as pos- 

 sible. When the disease first sets in stir the soil about the plants 

 and do everything possible to dry the soil without killing the 

 plants or raising the temperature, keep the temperature as low as 

 the plants will bear. If this does not save them change the soil 

 and clean the beds by whitewashing them. 



When cuttings become seriously diseased change them to fresh 

 soil, resetting only the perfectly healthy ones.
