The pools and water-courses generally have required bul little 

 attention. During the severe storms of lasl summer considerable 

 damage was done by the exceptionally heavj flow of water. The 

 effects of similar storms in this portion" of the park have beer 

 anticipated, by suitable provision for carrying off tli i water, and 

 preventing unusual accumulations. 



DRAINAGE. 



The drainage of the southerly end of the Long Meadow, at the 

 date of the last report, included only the construction of a brick 

 sewer some GOO feet distant from its outlet in the upper pool. 

 From this sewer lines of eighteen and twenty-inch pipe were laid 

 towards Fifteenth street on the south, and to the district between 

 the west drive and Ninth avenue. Necessary man-holes have 

 been built, and with these connections have been made to basins 

 for draining walks and plantations. These pipes are generally laid 

 in a straight line, with a uniform grade between man-holes or 

 basins, with the view to obviate the liability of stoppage of the 

 flow of water in the pipes, and to secure the means of discovering 

 and removing any obstruction as easily as possible. 



The fifteen-inch main crossing the west drive, near the former 

 line of Sixth street, has been extended towards Ninth avenue, in 

 order to drain a pond midway between the drive and the avenue. 

 A ten-inch branch line has been laid from this to drain a second 

 low point near the drive and the former line of Eighth street. 

 The required basins and pipe connections were made in advance of 

 the conrpletion of the walks and surfaces along the west lake drive. 

 Where necessary, the usual provision of tile draining has been 

 arranged in connection with the general system. 



WELL AND WATER DISTRIBUTION. 

 The pump at the well has been worked during the largest pari 

 of the year for twenty-two hours per day, to -fill up and maintain 

 the supply for the lake. Early in the spring a wrought-iron 

 cylinder four feet in diameter was introduced under the suction 

 pipe, for the purpose of pumping the water in the well to a lower 

 level. During the year, the twelve-inch wrought-iron and cement 

 pipe required to finish the circuit along the base of Lookout Hill 

 was laid, thus completing the pipe system for water supply 

 adopted in 1807. Galvanized iron pipe has been laid to supply 

 water for drinking and other purposes at the pedestrian concourse 

 and the temporary music ground ; also a lead pipe has been laid to 

 supply the shelter at the playground.
