These two bridges together with the one built two years 
ago across the Bronx River at the northern end of the Garden 
provide all the driveway bridges called for in the general 
plan of the Garden. The general plan provides for two foot 
bridges, not yet built, one to replace the present wooden 
‘« Blue Bridge” at the north end of the hemlock grove, plans 
for which are submitted to you herewith, and another foot 
bridge to cross the Bronx River at a point where the fruti- 
cetum plain joins the north meadows; this is not required at 
present, however. The ‘Blue Bridge” ought to be rebuilt 
this year, as it is doubtfully safe on account of its age and 
requires rather heavy maintenance charges to keep it in order. 
Grading 
The excavating of rock along the path just northeast of the 
public conservatories required in establishing the contour of 
the ground called for by the general plan was completed early 
in the year and the necessary earth filling made at this point ; 
this was allowed to settle during the summer and the whole 
area topsoiled and sown during the autumn, thus completing 
the finished surfaces in that part of the grounds. 
Excavation of rock and earth at the rear of the museum 
building made necessary in establishing the contour of the 
grounds called for by the general plan has been prosecuted 
at intervals during the year and much progress has been 
made. The material excavated has been used for filling at 
the bridges and for the telford foundation of driveways and 
paths, for filling against the railway at the western end of the 
valley of the lakes and for the filling between the retaining 
walls at the Mosholu Parkway which is still going forward. 
These excavations are in capital condition to be continued 
during the winter. 
Much grading has also been done along the sides of the 
driveways under construction east of the Bronx River, and 
little now remains to be done there.
