barren, pond, meadow, and woodland. Nearly all the native plants 
established here, with the exception of

of general interest are wel 
the limestone (calciphile) ferns, for which there is as yet no suit- 
able place. Although the section is not yet open to the general 
public, arrangements may be made with the Curator of Public 
Instruction for its inspection by botany classes, to whose needs this 
area 1s especially adapted. 
Rock Garden 
The Rock Garden, constructed in the spring of 1916, is, in point 
of time, perhaps, the first rock garden of any considerable 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 
course of grading operations on other parts of the grounds; they 
‘native ” rocks on Long Island, with the exception 
are the only ‘ 
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 almost 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.

Rose Garden 
The Rose Garden, occupying about one acre in the northwest 
part of the Botanic Garden, was formally opened to the public 
on Sunday afternoon, June 24, 1928. This garden was made pos- 
sible by a gift of $10,000, later increased to $15,000, from Mr. and 
Mrs. Walter V. Cranford, of Greenwich, Connecticut. 
The general plan of the Garden is as follows. At the north 
end, entrance is gained through a Doric pergola. Three parallel
