Excerpt from A Plain and Easy Account of the British Ferns: Together With Their Classification, Arrangement of Genera, Structure, and Functions; And a Glossary of Technical and Other Terms

Constructed case. Broken flower-pots, cinders, bits of sandstone, and then a compound of peat-earth and silver sand, should fill these pans or cases, and porous bits of stone forming artificial rocks may be built up and around the ferns when they are planted. On these rocks, mosses and lycopodiums will grow and thrive. For the covering of the commonest kind of case, obtain a bell-glass just large enough to fit tightly round the edge of the pan, so as to exclude the external air. This may be removed occasionally, and the fronds sprinkled with water, but not too often; and, as far as possible, the glass Should be kept bright and clear. The soil, before being used, should be care fully sifted, to prevent any worms or insect eggs being admitted with it. Any appearance of blight may be treated with lime-water.
