voir through the grounds in 1896, has been completely re- 
moved and used for filling at the east end of the long bridge 
and along the driveway east of the Bronx River. The valley 
which it occupied may now be restored to its natural contour 
by a coating of topsoil, after which the only indications that 
this temporary railroad existed will be noticed in the swathe 
cut through the woods where the trestle crossed the river; 
this gap has, however, been planted with rapid growing trees 
during the autumn, which should essentially close it within a 
few years. 
Drainage 
The operations of the past year have included very little 
addition to the drainage system, this having been previously 
essentially completed in the areas where work has been go- 
ing on. Considerable still remains to be done in the northern 
parts of the grounds, and east of the Bronx River, which 
may conveniently be taken up from time to time. 
Water Supply 
The completion of the finished surfaces along the path 
northeast of the public conservatories made it possible to 
complete the water pipe circuit around these buildings, and 
sufficient four-inch cast-iron pipe to do this was put in during 
the autumn, together with hose taps for irrigation. 
The building of the bridge across the valley of the lakes 
made it possible to extend the main six-inch water supply 
northward along the west side of the main driveway for about 
five-hundred feet, which was also accomplished in the autumn, 
and a hydrant set at the high point on this line. 
The details of all this construction work on roads, paths, 
bridges, grading operations, drainage and water supply will 
be found in the report of the Superintendent of Grounds, 
hereto appended. 
Buildings 
No new buildings have been constructed during the year. 
Accounts of their maintenance, the placing of additional 
furniture and other details, will be found in the report of
