PROPAGATION, DEVELOPMENT, AND CULTURE. 29 
bricks being that most commonly substituted. With taste 
in the distribution of these and suchlike materials, and in 
the planting of the Ferns, a very pleasing effect may be 
produced ; and on rockwork of this kind, if it be erected 
in a shaded and sheltered situation, and liberally supplied 
with percolating (not stagnant) water, and if the soil be 
of a texture which will admit of being thus constantly 
moist without becoming soddened and soured, nearly all 
the English Ferns may be grown successfully. 
It will, as a matter of course, suggest itself to the 
planter, that the most sunny, most exposed, and least 
moistened positions on the rockwork should be appro¬ 
priated to those species which grow naturally in situations 
to which these conditions afford the nearest resemblance; 
while, on the other hand, the kinds which naturally prefer 
the deepest shade and the dampest soil, should be placed 
in the positions where these conditions are most nearly 
imitated. 
Perhaps, however, the most interesting occupation for 
the amateur Fern-grower consists in the cultivation of 
them under glass, either in pots, or planted in a Wardian 
case. All the species admit of being grown in pots, 
and when developed under the protection of a covering
