FERN ROCKERIES INDOORS 103 



Others equally fine have been grown on 

 small tables placed at the left of the opening 

 of a southern bay window where slanting 

 rays strike the ferns only in the afternoon. 

 Again I insist that revolving cliffs, not being 

 in the natural order of events, the temptation 

 to turn things around must be resisted. 



As for temperature, no arbitrary rules can 

 be given. Of course the cooler the situation 

 the less the moisture required.
