144 The Fern Garden. 



damp enough, unless it should happen to be unex- 

 ceptionally dry. In that case a sprinkle overhead will 

 be of immense benefit to them. The planting should 

 be conducted so that each species gets a position that 

 bears a close affinity to the circumstances in which it 

 is found in a natural state. Those that grow on stone 

 or brickwork should be secured to those substances, 

 whilst those growing in damp pools and ordinary soil 

 should have like positions allotted to them. By taking 

 notice of the conditions under which they are found, a 

 good idea of the treatment they require may be formed 

 by those who know little or nothing about the subject. 

 The cultivator will find every bit of information picked 

 up in this way of very great service to him, at some 

 time or other. 



The undermentioned species are all particularly 

 beautiful, and have the great merit of thriving un- 

 commonly well upon an artificially constructed rockery : 

 — Bartramia fontana, B. pomiformis, Bryum alpinum, B. 

 capillare, B. argenteum, Dicranum squarrosum, Grimmia 

 Doniana, G. leucophcea, G. pulvinata, Hookeria lucens, 

 Hypnum denticulatum, H. cupressiforme, H. purum, R. 

 Schreberi, H. splendens, Leskea sericea, Racomitrium 

 canescens, Weissia contraversa, the principal species of 

 Tortula, and all the Polytrichums, and Mniums.
