nature of which encourages the travelling propen- 

 sities of the roots. Few ferns like to be sodden 

 in this manner at their roots like Thelypteris. In 

 cultivation the nearest approach to the natural 

 conditions which have been described must be 

 attempted. If planted in the rockery the lowest 

 tier should be appropriated for its roots, which, 

 when practicable, may be kept immersed in water 

 or perpetually soddened peat soil. If it be kept 

 indoors in pots these must stand in pans of water, 

 and under such conditions you may successfully 

 grow this beautiful fern.
