appeal to me. But no garden can be without the finer 
varieties of Calluna (Hayes, of Grasmere, has a white 
form so long and elegant in the spike as to suggest a 
Spiraea japonica), and the various hardy species of Erevca 
itself—carnea, mackayana (lovely, if impermanent as 
this fleeting world of false desire)—lusitanica, mediter- 
ranea, ciliaris. This last is a rare, beautiful little native 
from Dorset heaths, with heads of big brilliant bells. 
Another is vagans, from Cornwall, with fine bushy spikes 
of white. All these enjoy hot, sandy, peaty soils, and 
have no marked love for me. Mediterranea, however, 
thrives brilliantly, and blooms at the most improbable 
times, while usitanica has now formed a great tall bush 
of five feet high or so, which makes a delightful filmy 
shelter for Epigaea repens. And of my heaths, the most 
precious is the Irish Bell-Heather—Daboeocia polifolia— 
which you will see on either side of the road as you drive 
across the wild land between Sligo and Galway, through 
Connemara. This is a very easy-going plant, which 
luxuriates with me, and even more in peatier corners of 
England, with ovate leaves and long, loose spikes of very 
large white or rosy-purple bells, carried on stems about 
eight inches high, and precious, like Hreica carnea, in the 
rock-garden, for its habit of blooming from early till late. 
Under the shelter of Hreica, too, come such things as 
Arbutus, Vaccinium, Arctostaphylos, these two last species 
containing one or two useful little things for the peaty 
rock-garden, which, besides possessing no dizzy degree of 
charm, are too hostile to my garden to earn a more 
exhaustive notice here. 
The Gaultherias give us one big, ramping undergrowth 
in G. shallon, a North American unworthy of a choice 
place; and another most precious and elect of dwarfs in 
tiny, rare G. trichophylla, which you must grow in peat, 
among stones, at the bottom of a little hollow like a
