In spring, with the aid of Miss Elizabeth Clarke, curatorial 
— 

assistant, various improvements were made in the herbaceous 
plantings. The number of food plants and other useful plants was 
increased, and we hope to further increase this next season. 
Duplicates of Dianthus and Gypsophila were discarded, and the 
remainder separated, one bed for each genus. Similarly, Poten- 
filla and Geum were separated, and the Labiatae and the Cam- 
panulaceae were rearranged. 
To make the needed improvements in the herbaceous beds, part- 
Co 
time assistance of a gardener during spring and fall is much needed. 
In the nursery a slat or shaded area is much needed. 
TREES AND SHRUBS 
Mr. Charles Doney, assistant in woody plants, reports on the 
planting of many trees and shrubs and on continued checking of 
labels and maps. Specimens were collected of additional trees, in 
particular of a number which have not yet flowered. In Novem- 
ber, Mr. Doney visited the Arnold Arboretum for a number o 
days to study the collections there, and to collect seeds. Among 
species added, which we have not had previously on our grounds, 
are Daphne Burkwoodit, lex macrocarpa and Magnolia cordata.

HaLr-Harpy Woopy PLANTS 
lor several years we have been accumulating collections of 
half-hardy trees and shrubs south of the Rock Garden and espe- 
cially in the protected north end of the nursery. These include 
a number of plants we have not been able to grow in more ex- 
posed situations in the Garden. Many people have been inter- 
ested in these plants, which were listed in the Guides to Trees 
and to Shrubs recently published. It is probable that, by special 
attention to their requirements, several additional Southern spe- 
cies nught be grown in these areas. It would be desirable to 
rearrange paths and plants there somewhat so as to be able to 
reach the plants more easily. Some protection from winter sun 
would be desirable. Rabbits, also, cause serious trouble, especially 
in the nursery.
