maining ones needed may be excavated in the spring, in time 
for the installation of the groups of aquatics which we have 
hitherto been unable to cultivate in positions where their bo- 
tanical relations to other plants would be indicated. 
Weeding and repeated mowing of the greensward between 
the beds have brought this to a very presentable appearance, 
and the wooded margins of the tract have been utilized for 
the planting of shade-loving species, for which they are so 
well adapted. 
Fruticetum. Theremoval of shrubs from the nurseries and 
borders to the plain northeast of the Museum Building, set 
apart for the fruticetum, was begun in October, and by the end 
of the season 195 species had been installed, as shown by the 
list appended to this report. The plants have been grouped 
in natural families, with due consideration of the positions of 
future roads and paths, as provided in the General Plan, which 
contemplates a large amount of greensward between the planta- 
tions. As a rule only shrubs of considerable size have been 
moved into this collection; nearly as many more species, de- 
rived from seed or cuttings, remain in the nurseries for an- 
other year’s growth. 
Arboretum, The setting of trees, not hitherto represented 
in the grounds, in places planned for them in the arboretum 
spaces, was carried on through both spring and autumn. 
The trees were mainly selected from the nurseries and borders, 
the best individuals of each kind being chosen. A list of the 
species set out, together with those native to the tract or long 
ago established, numbering 178 kinds, is appended. In plac- 
ing the new trees, care has been taken to keep them at safe 
distances, from the future driveways, as laid down in the 
General Plan. 
Viticetum. A substantial rustic arbor, about 600 feet long, 
has been nearly completed for the climbers and twining 
plants along the edge of the forest, southeast of the Museum. 
The primary planting of this collection may be accomplished 
the coming spring. Trailers may be established along the 
rock-ledges near by.
