86 JOUKNAL OF THE RoYAI. H( )RTICrLTrRAL SOCIETY. 
I regret that time and space forbid my going more fully into this 
subject, which I love so well ; and I am afraid that I have disappointed 
those who expected new theories on rock-building. But I nevertheless 
venture to hope that my few hints, which are based on the study of nature 
and on practical experience alone, may at least not be altogether unwel- 
come to those about to embellish their gardens by the addition of a rock- 
garden, pond, or streamlet. 
APPENDIX. 
The Plants suitable for the rock-garden, ponds, and banks of stream- 
lets are numerous indeed : a mere list of them alone would fill a large 
book. I can make no attempt, therefore, to give anything like a complete 
list, but I will, under various headings, give the names of at least a few 
as indicating the type of plants which from experience I consider worth 
recommending for various positions. For easier reference I have divided 
most of the plants into two groups, namely, for sunny or slightly shaded 
positions and for more or less shady positions. It is of course impossible 
to draw a hard-and-fast line between these two groups, and some of the 
plants enumerated under the shady section will be found almost equally 
as suitable for sunny positions, and vice versa. The distinction made 
must therefore be considered a rough guide only. 
List No. 1. 
Small Plants for vertical or abruptly sloping fissures, suitable for 
being associated together in the most select part of the rock-garden, 
where they might be planted sideways, i.e., with their roots in a more or 
less horizontal position, as previously described.
