THE SOWING OF SPORES. 2$ 



While still very small, the plantlets should be pricked out, 

 and for some time thereafter they should be subjected to the 

 same conditions as before. Spores are so exceedingly small 

 and light that the greatest care must be exercised in growing 

 them. In order to gather them, the fronds may be cut as 

 soon as the sori or fruit-dots turn brown, and stored in close 

 boxes or paper bags. When the spores begin to discharge 

 freely, the frond may be shaken over the pot, or it may be 

 broken up and pieces of it laid on the soil. 



NOTE. For tables of weights and longevities of seeds and quanti- 

 ties required for given areas, consult The Horticulturist's Rule-Book.
