170 BRITISH FERNS. 
Andrews appears to have been still more successful: 
He says:—I have had a case made purposely for 
cultivating this fern. I lined the bottom with zine, 
and covered the frame-work with oiled lawn. I then

post of loam and coarse sand, interspersed with pieces

the case, attached to rods covered with bass-matting 
and moss. The plants were kept cool, avd were well

of large and strong growth. No other fern

but will never attain a vigorous state of growth. 
The cultivators of the Bristle Fern are under a mis-

loaded with moisture. In the drier counties of England 
this can only be obtained by a constant covering of 
glass. Several plans have been tried for accomplish- 
ing this. I will describe three, ne ene
