FERNS AND AQUARIA.

ralist to construct a fernery and aquarium for 
himself; and whenever such a work is attempted, 
it should always be remembered that the most 
pleasing and successful results will always be 
attained by the closest possible imitation of 
Nature. How often have we not all admired the 
rocky embankment of a trout-stream, for instance, 
fringed by the waving fronds of Ferns; and if we 
were to explore the submerged holes and crevices 
in such a rocky embankment, we should find that 
they furnished habitats as congenial for the fish 
in the streams as in their way are provided for 
the Ferns above by the holes and corners in the 
superposed rocky masses. Half an hour’s careful 
study of a ferny streamlet would indeed afford 
more than one valuable lesson in the art of 
bringing Ferns into association with aquaria in 
our homes.
