be well to mention that in pricking out the rooted Ferns 

 the soil should be only just moist enough to permit of 

 holes being made to accommodate the roots, each plant 

 being pressed gently firm with the finger as it is installed.

 immersed in water until the water percolates from below 

 to the surface and so saturates the soil, the operation is 

 then completed. To prick out into wet soil does well

 young plants showing the same peculiar slenderness and 

 length of the subdivisions as in the Druery f^racillimwns
