341 feet above sea level, and the storage reservoir to 280 _ 
above sea level, would be a delivery of two million gallons dail 
sores one million er" to fecm mane besides seven million 
gallons to Paddington, or 10-4 million gallons to Crown-stre 
The ity actually Seanad for ¢ the pipes is to deliver during 
ordinary seasons, when the supply will joey the demand, two 
million gallons daily to Waverley heights, 325 feet above sea leve l, 
one million gallons to Woollahra, 276 feet aad sea level (which 
one pipe would manage in fourteen hours), and thirteen millions 
of gallons to Paddington, 214 feet above sea level. The surplus 
water from the canal would flow over a weir on the western flan 
of the dam into the storage reserv rvoir. u seasons of drought,

and Cataract Rivers, and of the actual flow of water in those 
Streams, the result of careful observation extending over many
