graded. A portion of the quarry area northwest of the 

 museum building, measuring 125 by 200 feet, was graded 

 and sown, a total of 1,965 cart loads of stone and earth 

 being required to complete this work. 



The grading of the grounds and excavation for the cellar 

 and foundations for the additional greenhouses now under 

 construction has been partly completed, 700 cubic feet 

 of stone and earth having been removed and used to regu- 

 late the grounds and paths southwest of said houses. 

 Considerable grading has been done elsewhere in that 

 vicinity along existing and new paths and roads. The 

 record shows that 5,762 cubic yards of earth, 2,830 cubic 

 yards of stone, 302 yards of screenings, 138 team loads of 

 boulders, and 100 loads of rubbish were hauled and dis-

Drainage 



Much work of this kind has been done, especially in the 

 north meadows west and east of the Bronx River. In 

 underground drainage, we have laid a line of ten and twelve 

 inch sewer-pipe measuring 528 feet from the low point 

 of the upper meadows east of the river draining south into 

 the river; with which line 200 feet of twelve-inch pipe 

 draining the old creek, and 20 feet of twelve-inch pipe 

 taking the waste water from Power House No. 2 and sur- 

 roundings, have been connected. 



In the valley opposite the curve of the river road, 350 

 feet of eight-inch pipe was laid to connect the drain pre- 

 viously constructed, draining the water of the new conser- 

 vatories and eight catch-basins, of which four have been 

 newly constructed, to a culvert emptying into the river; 

 also 168 feet of six-inch pipe has been laid to drain said 



The twelve-inch pipe draining the eastern grounds near 

 the stable has been extended 200 feet, from the southeast 

 corner of the Long Bridge to the small lily pond north of 

 the foot bridge; also 50 feet of three-inch pipe has been 

 used to drain a drinking fountain in the vicinity.
