must be named, as well as the old D. Cneorum and the 
newer Fioniana. Among Berberis, nothing taller than the 
useful dwarf B, dulcis nana can well be included here. But to it 
must be added the pretty procumbent B. empetrifolia. 
It is a moot question whether variegated forms are wisely 
admitted to the rock-garden. Anything like positive pronounce- 
ment is out of place, and it is really a question of taste. If 
they are admitted, the Box and the Yew will contribute more 
varieties than they otherwise will. But in any case they 
contribute many. Tree Ivies I personally admire much, and if 
not admissible to the ideal Alpine garden (for in the high Alps 
the Ivy is not found), they will be found useful in any other rock- 
garden. And while the commoner Ivies are things to be there 
studiously avoided, there are some few beautiful little forms, like 
H. conglomerata and minima, which are in place and keeping. 
These, along with Euonymus radicans variegata and a few 
others, are wanted for the special purpose of lightly mantling, 
without wholly concealing, a too naked surface of rock. Finally, 
I must name that pretty little silver-frosted shrub, Santolina 
alpina (not to be confounded with the grosser S. incana), as a 
subject too little used for imparting variety of leaf-colour to the 
picture. 
I have not probably even indicated — certainly, I have not 
enumerated — one-half of even the best evergreen shrub furniture 
available for our purpose. But it is time that I turn towards 
another part of the subject. 
The evergreen furniture should, in my judgment, not only 
consist of shrubs. I strongly recommend the inclusion, if only 
for the sake of their foliage, of large masses of carpeting plants. 
I instance among the best things for this purpose the silvery 
Antennarias, the Thymes, especially the Woolly Thyme {T, 
lainifjinosus), the deep, yet vivid, gveen Ilerniaria glabra, and its 
golden variety ; Veronica j^^'osiraia, a sheet of brilliant blue in 
spring and summer, and of neat and pleasing foliage always ; 
Veronica rcpens, a close-growing turf of " milk and water " blue 
flowers ; and mossy, even incrusted, Saxifrages. The masses of 
such evergreens as these may take many forms: ''mats" of 
tli(!iii upon the tops or sides of the mounds or banks; *' cascades " 
of them over projecting rocks or ledges ; flowing streams of them 
in tlio giillies; spreading Hoods of them in the lower ground of
