the main driveways here had grown so dense as to obstruct 
the view, so much so as to make driving dangerous at this 
point; the view was restored by thinning the plantation 
materially. The shelter-house planned for this plantation 
will be a very beautiful structure, to be located near the 
forest border to the east. 
3. Salicetum 
The collection of willows in the north meadows has been 
modified only by the elimination of certain specimens, 
which were removed in order to improve the form of con- 
tiguous trees. 
4. Deciduous Arboretum 
As suggested as desirable in my last annual report, con- 
siderable work was accomplished at various points in the 
arboretum area which occupies the whole eastern side of 
the reservation, the specimen trees being planted over an 
area of about three-quarters of a mile in length. Most of 
the new planting was done at the extreme southern end of 
this arboretum tract, where mainly additional poplars, 
willows, and walnuts were set, but additional species and 
varieties were brought into the collection at various points. 
The survey of the hardy woody plants in the Garden car- 
ried out by the Head Gardener took the form of an enum- 
eration of the species and varieties, which is being printed 
in successive issues of the Garden Journal and the parts 
reprinted, so that we shall soon have a little book which will 
contain this information, the catalogue giving the botanical 
and common name of the plant, its location within the 
Garden, and its distribution in nature. This survey was 
extended from the trees to include the shrubs and woody 
vines. In order to commence to make the arboretum 
collections more readily accessible to visitors, a considerable 
extension of the path system was commenced and largely 
graded, the top-soil obtained from excavations for the new 
paths being used in building the rose garden.
