 seed pan 



to keep the soil sweet by causing it to dry out 

 more rapidly; second, it allows the air to 

 enter the soil and so come in contact with 

 the roots. Any form of glazed pot, therefore, 

 which will prevent the evaporation of the ex- 

 cess of moisture from the soil and which will 

 exclude the air from the roots should be avoided.
