10.78 inches, or to an average of 513,165 gallons per square mile 

 per day. or to 0.79 of a cubic foot per second per square mile. In 

 the water year of 1880, with a total rainfall of 40.04 inches, the 

 water utilized amounted to 12.37 inches on the catchment, or to 

 587,568 gallons per square mile per day, or to 0.91 of a cubic foot 

 per second per square mile. In 1881, with a rainfall of 41.52 

 inches, the total utilization of w r ater amounted to 11.64 inches on 

 the catchment, or to 554,473 gallons per square mile per day, or 

 to 0.86 of a cubic foot per second per square mile. This drop in 

 the unit of utilization merely shows the effect of the increase in 

 the area of the catchment. 



The tributary catchments remained at 59.4 square miles until 

 August, 1883, in which month the Spring creek and Baisley's 

 driven-well stations w-ere started. From this date the tributary 

 catchment area is taken at 64.6 square miles. Spring creek and 

 Baisley's stations marked the beginning of the Brooklyn driven- 

 well system. In the water year of 1884, with a total rainfall 

 of 43.44 inches, the utilization was 12.53 inches, amounting to 

 594,992 gallons per square mile per day, or to 0.92 of a cubic 

 foot per second per square mile. 



In May, 1885, the Forest stream and Clear stream driven-well 

 stations were started, thereby increasing the tributary catch- 

 ment area to 65.4 square miles. In the water year of 1886, with 

 a total rainfall of 50.43 inches, the water utilized amounted to 

 14.40 inches, equivalent to 685,521 gallons per square mile per 

 day. or to 1.06 cubic feet per second per square mile. 



The catchment area remained 65.4 square miles until June, 

 1890, when it was increased to 65.6 square miles by the addition 

 of the Jameco park driven-well station. In the water year 1891, 

 with a total rainfall of 40.34 inches, the water utilized amounted 

 to 18.48 inches on the catchment, equivalent to 879,811 gallons 

 per square mile per day. or to 1.35 cubic feet per second per 

 square mile. 



Large extensions of the works were made in 1890 and 1891, 

 so that will) the beginning of pumping at Millburn on December 

 17. 1891, the tributary catchment area may be considered as 

 increased from 65.6 to 154.1 square miles, an increase of 88.5 

 square miles. In the calendar year 1892, with a rainfall of 37.75 

 inches, the water drawn from the original catchment of 65.6
