lumps of concrete were treated with an iron salt to soften their 
harsh and forbidding color. On this small area, Mr. Malby, 
addition to growing a respectable collection of alpines, had a pool 
and a bog garden. A full account of this interesting garden may 
be found in The Story of My Rock Garden, by Reginald A. 
Malby 
Mr. Clarence Lown, at Poughkeepsie, created a rock garden 
of which any country might be proud. In his garden, Mr. Lown 
did not attempt any pretentious landscape features. The garden 
on the whole consists of flat rocky beds, yet it is charming and 
restful and, as previously mentioned, contains an amazingly good 
collection of alpine and rock plants. 
Mr. and Mrs. Walter Beck have made a delightful and artistic 
rock garden at Millbrook, New York, by adapting a steep slope 
overlooking a lake to the needs of a rock g garden and by construct- 
ing rock work on the upper levels. In this garden, alpine, rock, 
woodland, and bog plants grow in happy profusion. The beauty 
of the garden is further enhanced by the lavish use of water in the 
form of rivulets and pools. This may serve as an example of a 
rock garden partly natural, partly artificial, part of it in the open 
(a necessity, if alpines are to be grown), and part in woodland. 
In many gardens advantage has been taken of natural outcrops 
of rock to construct a rock garden. Such gardens are usually 
the most convincing from a landscape standpoint, though they do 
not always provide the maximum in respect to the cultural re- 
quirements of the rock plants unless considerable tinkering is done 
with a view to providing bigger and deeper “ pockets” for them. 
Alpines and rock plants can be used to good advantage in parts 
of the garden other than the rock garden proper. They are, of 
course, the plants for wall gardening, and are well adapted for 
use in “ pavement planting "—that form of gardening which uses 
plants in the crevices between flagstone walks. The problem of 
a satisfactory dividing line between perennial border and walk 
can often be solved by using rocks and planting between them 
with alpines so that they become partly covered with vegetation. 
This has been done with great success in many gardens and notably 
so at Aldenham House, near London, England, where a gravel 
walk is separated from the border by a device of this nature, thus
