several years in order to establish the finished grades, has 
been continued, and several thousand cubic yards of material 
have been taken from that point for the foundations of roads 
and paths and for embankments about the lakes and else- 
where. 
The filling necessary about the retaining walls at the 
approaches to the Mosholu Parkway and the Woodlawn 
Road was completed, covered with topsoil and either sodded 
or sown during the season. 
The filling required along the railway at the west end of 
the valley of the lakes, between the railway and the driveway, 
has been nearly completed and the finished surfaces topsoiled. 
The grading required at both ends of the lake bridge has 
been nearly completed and a portion of the embankment here 
has been topsoiled and sodded. 
The banks along the driveway crossing the fruticetum 
have been completed, topsoiled and sodded or sown, except 
near the west end of the long bridge where some grading 
still remains to be done. Considerable work in excavating 
and filling to form the finished banks along the driveway on 
the eastern side of the Bronx River north of the long bridge 
has been accomplished, as also along the main driveway east 
of the long bridge. 
Much grading has been done at the site of the economic 
garden, east of the museum building, and the surfaces here 
have been completed and made ready for planting. 
In addition to these larger works, minor grading operations 
have been carried out in various parts of the grounds. 
Drainage 
In the course of the construction of roads and paths, and 
in grading operations, additional grass gutters, catch-basins, 
and drain-pipe connections have been built at the Mosholu 
Parkway and Woodlawn Road approaches, at the lake bridge, 
and on the fruticetum plain. At the economic garden, a 
ditch with stone sides has been constructed to receive the 
surface drainage of the valley, and lead it to the water system
