REPORT OF PARK COMMISSIONERS 27 



are irrigated by water which costs about one cent per 1000 

 gallons. Lloyd Lake, Metson Lake and Spreckels Lake are 

 supplied from the reservoir. These wells on the Ocean Beach 

 also comprise the present source of supply for Lincoln Park. 

 The water is conveyed through a 10-inch iron pipe, one mile 

 and a half in length, to the crest of Lincoln Park, 360 feet 

 above sea level. The power for pumping is supplied by an 

 electric motor. Further development of fresh water sources 

 to secure an adequate supply for Lincoln Park is proposed 

 by the Commissioners. 



The development of streams near the Ocean where many 

 experts asserted that fresh water could not be procured, and 

 the lifting of the water by the power of summer winds from 

 the sea level 200 feet high and two miles distant, comprise 

 an achievement that will ever be commended. 



Moreover, the present Board faces the problem of lighting 

 the Park. The old system is obsolete in many places and 

 generally speaking inadequate, as it was badly shattered by 

 the earthquake of 1906. As an abundance of electrical energy 

 is available in the mountains, the Commissioners may deem it 

 wise to abandon the system of generating electric current 

 from its own plant and purchase light and power from corpo- 

 rations that have constructed great plants to supply the needs 

 of San Francisco. It is noted here that in April, 1911, the 

 South Park Board of Chicago made a five years contract for 

 the delivery of electric current at a price of three-quarters of 

 a cent per kilowatt hour. The cost of generating the cur- 

 rent by an independent plant constructed by the Chicago Board 

 was one cent and a half a kilowatt hour. 



MAINTAINED AT ACTUAL COST 



The Park Commission of San Francisco does not derive 

 any revenue to speak of from these sources known to park 

 management in the eastern cities as concessions. The Japanese 

 Tea Garden, a feature of Golden Gate Park that ministers 

 at once to the delight and admiration of tourists, is a conces- 

 sion that pays only $50 per month.
