ever possible to maintain under the old very unsatisfactory 
conditions. 
All of the houses in this range have improved in appear- 
ance, the change in the cycad house being particularly 
noticeable. Additions of rare palms and ferns, as well as 
economic fruits, have been made to the collections. 
MAIN GARDEN 
Two outdoor gardens have been added during the year, 
namely, the formal garden, located back of the main con- 
servatory, and the Linnean garden, surrounding the Lin- 
nean house at the north end of the Garden. Detailed de- 
scriptions of these two gardens appeared in the April num- 
ber of the Butietin and need not be repeated here. 
Numerous additions have been made to the permanent 
planting of new beds with hardy perennials and shrubs, and 
a considerable rearrangement of the walks has been accom- 
lished. Owing to the erection of the experimental green- 
ouses, a replanting of part of the rose garden was neces- 
sitated, and some forty beds were added south of the pergola. 
GIFTS OF PLANTS 
The year 1915 has been marked by an unusual number of 
valuable additions made by gift to the various collections 
of plants at the Garden. 
Mr. D. S. Brown, of “Brownhurst,” Kirkwood, Missouri, 
whose collection of orchids is known throughout the world, 
has recently presented to the Garden some of his choicest 
plants, and these, added to the orchids already at the Garden, 
constitute one of the largest and most representative collec- 
tions of this interesting group in the country. Among the 
orchids obtained from Mr. Brown was a collection of cypripe- 
diums, including over 130 plants of C. insigne, C. Leeanum, 
and various hybrids; a collection of dendrobiums, including 
thirty plants of D. nobile and its hybrids; a miscellaneous 
collection of laelias and cattleyas, including such species as 
Laelia purpurata, L. crispa, L. tenebrosa, L. Boothiana, Cat-
