a dirt embankment several hundred feet long was made by 
the contractor through a valley from the eastern end of the 
trestle nearly to the Garden barn; the abandonment of this 
railway by the contractor during the past summer has given 
opportunity for using this embankment as filling for the 
driveways at the east end of the long bridge, where it is now 
being hauled; its removal will restore this valley to its orig- 
inal form. The abandonment of this railway has also made 
it possible to regulate and grade the grounds just west of the 
arn. 
Drainage and Sewerage 
The laying of the drain from the cellar of the museum 
building to the upper lake, commenced late in 1903, was com- 
pleted in the spring; this work necessitated cutting through 
rock to a depth of about 14 feet for a considerable distance, 
and putting in a 10-inch earthenware pipe, which now com- 
pletely controls the drainage of the building and will ulti- 
mately come into use for the drainage of the court. The 
sewer connection east of the Bronx River, on which work 
was commenced last winter, was also completed in the spring, 
providing satisfactory sewerage of the barn and also making 
it possible to build a public comfort station on the east side of 
the grounds, where the need of one is beginning to be ap- 
parent, 
A sewer connecting the public comfort station at the ele- 
vated railway approach with the large drain at the power 
house was laid early in the season. 
The 12-inch land drain east of the Bronx River, laid sev- 
eral years ago, was continued to the east end of the long 
bridge, outflowing into the river, before beginning the earth 
filling required for the approach at this point. 
Catch-basins and short drain-pipe connections from them 
to drains already laid, have been built at a number of places. 
Some drain-pipes were laid, and others relaid at the new 
propagating greenhouse at the nurseries. 
these sewer- and drain-pipes have been carefully plotted 
on our location plan, so that their position may be known in
