The Villa of Dr. Walker, in the neighbourhood of Dollar, we found one of the best laid out and highest kept places in Scotland; ranking in these respects with Crosslee Cottage. The art of growing low alpine plants on cones and hemispheres of pebbles is here carried to the highest degree of perfection; and it is difficult to imagine how much beauty and effect is thus produced by the saxifrages, sedums, thymes, the minor campanulas, and such like plants. Each cone or hemisphere is kept quite distinct, and they are displayed to most advantage when standing on a lawn or on a flooring of pebbles. They look well, however, on common borders. Ceanothus azureus stands the winter here without protection; and, though the place only contains two or three acres of pleasure-ground, yet, by not planting more than one or two plants of any one species or variety, the collection of trees and shrubs is so considerable, that it includes all the species procurable in the Edinburgh nurseries, and many procured from London.
