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 :
