FERXS 



fine river sand ; broken pieces of porous brick mixed with the soil 

 are also a useful ingredient and have a beneficial effect in main- 

 taining proper aeration of the soil. No manure should enter the 

 potting compost unless it be in a thoroughly decomposed state. 

 Thorough drainage being essential, the pots should be filled to 

 about a quarter of their depth with crocks. Many of the more 

 delicate ferns, such as Adiantums ( Maiden-hair ferns ) resent too 

 much water overhead, so that their fronds should not be unnecess- 

 arily wetted. Ferns are generally easily multiplied by division of 

 the roots, and those that produce fertile fronds may be propagated 

 by spores. See under Propagation. 



The following are some of the most ornamental ferns suitable 

 for cultivation in the tropics.
