Avenue to the eastern side of the Garden, where it was hidden 
among some pine trees along the Washington Avenue side of 
the grounds. A new one was also built for our increased num- 
ber of tools and implements, and a cold frame was constructed 
near by for the seed beds, and to serve as temporary propa- 
gating headquarters. 
On reporting upon the installation of the three collections 
which were started during the year, they will be considered in 
the order in which they were begun. 
The Morphological Section (Section III) 
According to specifications drawn up by you for this col- 
lection, there are 43 beds, 36 of which were made ready for 
plants, the remainder to be installed during 1912. In the 16 
beds devoted to “external anatomy” (Division 1), most of 
the plants needed were set out, some necessarily being omitted 
for the present, until we are equipped for growing greenhouse 
plants. The 20 beds illustrating “comparative morphology” (Di- 
vision 2), were also filled in as far as our present equipment will 
allow. Other plants for these beds have been collected during 
the year, and notes made for the completion of the collection in 
the near future. It would be desirable to replace, in so far as 
possible, plants now in the collection which are of transient 
duration or difficult of cultivation, for plants of more easy culti- 
vation and greater length of life, so that the utility of the collec- 
tion may be kept at its greatest and the cost of maintenance re- 
duced to a minimum. ‘There are few collections in the Garden 
of such permanent tenure as this, and the aim should be to install 
only those plants which, while adequately illustrating the par- 
ticular feature in hand, will demand the least amount of main- 
tenance expense possible. 
During the season 4 “blanket” labels or bulletins, 36 bed la- 
bels, and 203 individual plant labels were put in place, all of 
which will be discussed later under the heading Labeling. 
Economic Section (Section II) 
This collection was planned according to specifications 
drawn up by me before I came to the Garden, and approved by 
you. The plants used and their arrangement was determined
