on, a total of about fifteen acres more is so far advanced 
toward completion that it is expected that it will be brought 
into a finished condition during 1904. 
It still remains to remove the surplus rock from the exca- 
vations just north of the public conservatories which was 
piled by the contractor on an adjacent hillside, and to grade 
the rocky hill on which this pile rests, this work being the 
heaviest single piece of grading work that is still needed to 
complete the carrying out of the plan in the area south of 
the museum building; much of this rock will be used how- 
ever in the construction of the five-arched stone bridge across 
the valley of the Bronx River before alluded to. 
The grading operations in connection with the building of 
driveways in the northern part of the Garden have already 
been described under the heading of Roads and Paths. 
In the rear of the museum building work has been going 
on at times during the year in removing the surplus rock and 
earth necessary to form the court of the building in accor- 
dance with the general plan, and is still being prosecuted, the 
stone being distributed along the lines of paths still to be 
built, taking advantage of the frozen condition of the ground 
during winter for this heavy cartage, while the soil is being 
carted to points where additional filling is needed in grading 
and in the building of driveways. This work may profitably 
go on all winter. 
Drainage and Sewerage. 
At the commencement of the year work was being prose- 
cuted on the connection of the sewer and drainage system of 
the southwestern portion of the Garden with the Webster 
Avenue sewer, the line passing under the New York Central 
and Hudson River Railroad right-of-way under the approach 
at West 200th Street. The work was completed early in the 
spring, all necessary catch-basins and manholes constructed, 
and a rather difficult piece of work successfully accomplished. 
In completing the grading operations and paths in the 
vicinity of the public conservatories and along the driveway 
near the museum building, ten additional catch-basins were
