this is obtained during the winter or in the spring, this 
driveway may be completed and opened for use, with 
small expenditure. 
Construction of paths has been continued on both sides 
of the river, especially in the tract just south of the her- 
baceous garden, at the rose garden site, at the iris garden, 
and in the arboretum, and substantial progress has been 
made. In my last annual report, I suggested the desira- 
bility of competing at least a mile of additional paths during 
1916; considerably more than a mile of path has been 
partially completed, and stone for path foundations has 
been excavated and deposited in places during the winter. 
A commencement was also made on the construction of 
additional paths in the arboretum. 
During the season, the Park Department repaired and 
resurfaced the entire driveway system, and the road sur- 
faces have never before been in as fine condition as they 
are at present. The process of resurfacing has marred 
the grass borders of the roads in places; it is intended to 
repair these by sodding in the spring. As in previous 
years, the path system has been maintained by us, although 
this work is referred to the Park Department by the 
Garden’s charter. 
None of the bridges in the road and path system have 
required any repairs during the year; they are all in good 
order. 
Grading and Drainage 
At the new rose garden site, an area of somewhat over 
I acre was graded by excavation and by filling with top-soil 
averaging 2 feet in thickness, over 3,000 cubic yards of 
top-soil being used here, all of which was obtained in grad- 
ing paths in other parts of the grounds, following the 
general plan of development adopted. Considerable rock 
excavation was found necessary near the western entrance 
to the rose garden; this is now in progress, and the rock 
will serve to build the foundations of the path system here 
and of a considerable part of the path approaches. Con-
