dispersal. Goebers views are similar. Pfaehler then details his own 

 observations extended to all the groups of stegocarpous mosses ; and 

 finally gives a resum6 showing how the different parts of a moss may 

 contribute towards the emission and protection of the spores — pedicel, 

 capsule, peristome (simple or double), operculum, columella, and even the 

 spores themselves. The dominant biological principle is regulation in 

 the spore-dispersal by means of the peristome, columella, upright position 

 of capsule, etc. A second dominant principle is the protection of the 

 spores from water, by means of the peristome, by the formation of a 

 watery pellicle across the mouth of the capsule, etc. For in nearly all 

 the mosses spore-dispersal does not take place during rain.
