den ; grading and seeding down lawn on the hill southwest of the 
large conservatory; grading and seeding down lawn on a tri- 
angular section near Section II ; making and sodding about 10,000 
sq. ft. of terraces along the edges and near the southerly end of 
the esplanade and at the reservoir gate; grading and seeding down 
the esplanade and several adjacent areas; clearing rubbish from 
new (south) addition; grading site of experimental garden and 
new site for children’s gardens; and plowing, harrowing and 
planting of winter rye on same. 
A very considerable area has been put down to permanent 
lawn, following, with some changes, the scheme for soil improve- 
ment outlined in my first annual report. Much of this work 
could not have been done without liberal use of top soil for sur- 
face grading, and during the year we have received about 2,400 
cubic yards of this material. Of this, 1,720 cubic yards were 
purchased, and it is a pleasure to report that 680 cubic yards 
were presented through the generosity of Mr. J. J. Hillin and of 
the Norton and Gorman Company. 
A considerable amount of work has been done by both men 
and horses for the gardeners and for the children’s gardens. As 
before this force has been under the immediate supervision of 
Mr. Herman Kolsh, the regular foreman. 
Gardening Force 
The work in this department has been under the supervision 
of the head gardener, Mr. Montague Free. The force and its 
duties were the same as in 1914. Besides regular maintenance, 
which has increased very materially, owing to the growth of the 
collections the gardeners completed new work as follows: 
1. Planting 156 specimen trees of flowering dogwood (Cornus 
florida) on the esplanade. 
2. Economic House plants reset, and rene in groups accord- 
ing to economic use such as foods, fibers, drugs, etc., many 
of them being planted out permanently. 
3. Planting of conifers around the lake, both for additions to the 
Pinetum and as screen for the Japanese garden. Some 
deciduous trees were also planted for the latter purpose.
