will then only need pricking out and bringing on. If, on the other ` 
hand, our warning has been neglected, and a dense mass of tiny 
prothalli is engendered thereby, a larger pan can be prepared and 
sterilized as described, and tiny patches, pill-size, of these prothalli 
may be pricked out and inserted an inch apart and kept close 
with, probably, success, since room is thus afforded. When a 
number of sowings is in question, a good plan is to sow in small pots 
and embed these closely together in cocoanut fibre in a larger pan, 
covering the whole with one pane of glass. It will then suffice to 
keep the fibre moist until the plants appear. All sowings should be 
numbered and registered in a book kept for that purpose.
