idea of a Niwa, or landscape garden. From the tea house (near 
the east entrance) one can see the machiai or “ rest house,” the 
island with the drum bridge, bronze storks, stone and wooden 
lanterns, the waterfalls, and the wooden Torii standing in the lake, 
recalling the one at Miyajima, Japan. Since January 1, 1919, the 
Garden has been in charge of Miss Mary Averill, honorary curator 
of Japanese gardening and floral art, and has been steadily im- 
proved, under her supervision, by Japanese gardeners. For details

Rock Garden 
The Rock Garden, constructed in the spring of 1916, is, in point 
of time, perhaps, the first rock garden of any considerabie size in 
a public garden or park in the United States. The rocks used in 
its construction are glacial boulders which were uncovered in the 
s; they

course of grading operations on other parts of the grounc 
are the only “native” rocks on Long Island, with the exception 
of one small outcrop on the northwest shore. The general idea in 
making the garden was that of representing a boulder-strewn slope, 
but this design, of necessity, was modified in places to provide 
proper cultural conditions as to drainage, depth of soil, and shade. 
The garden is planted with about eight hundred species and vari- 
eties of alpine, saxatile, and other plants suitable for rock garden 
— 
culture. 
Although the rock garden enthusiast may expect to find some- 
thing of interest in bloom during every month of the year, it is in 
April, May, and June that the Rock Garden provides its greatest 
display of blossoms. Persons interested in rock gardening will

Garden, helpful; also, Leaflets, series XI, No.6, The Rock Garden.
