The systems were arranged with mains, secondary mains and laterals. 

 The mains were generally three inches in diameter, the secondary mains 

 two inches, and the laterals one and a half inches. 



Generally the mains followed the principal depressions in the surface, 

 the secondary mains, the minor depressions, and the laterals, were laid 

 out at intervals varying from twenty-five to forty-five feet, depending 

 upon the character of the soil, and were nearly at right angles to the 

 secondaries. 



WATER SUPPLY. 



The water supply for the Park water pipe system is at present 

 obtained from the Nassau Water Department. 



A sixteen inch main of this system connects with a twenty inch main 

 of the city distribution at a point near Prospect Hill reservoir. 



This main has branches of various diameters, diverging to different 

 parts of the Park. 



Hydrants are placed at convenient points along the drives for obtain- 

 ing water for sprinkling the roads, walks, and for other purposes. 



The patent cement pipe, manufactured by the Patent Water and 

 Gas Pipe Company, of Jersey City, has been adopted. 



It affords me great pleasure to acknowledge the very efficient assist- 

 ance I have received from Mr. John Bogart and Mr. John Y. Culyer in 

 their respective departments. 



The rapid and uninterrupted progress of the work this season has 

 been facilitated alike by the promptness with which all necessary sup- 

 plies and material have been furnished by Mr. Culyer, and by the in- 

 telligent energy displayed by Mr. Bogart, aided by his efficient corps 

 of assistants, in laying out the work to be executed. 



A degree of interest in the work and a harmony of action has been 

 exhibited throughout the whole Park organization which has been 

 especially beneficial to the work and gratifying to myself. 



In the labor department, Mr. John Maguire, the General Foreman, 

 has manifested an ability and energy fully equal to the arduous duties 

 of his responsible position, and has performed them in a highly credit- 

 able and satisfactory manner.
