water per hour above the surface of ground. July 1867. The well up to this time 
had been allowed to run to waste night and day, and it was found that the quantities 
supplied had diminished to 2,000 gallons per hour. Since then it has been econo- 
Inised, and it is found now that at any particular time it will supply about 5,000 
gallons per hour.
