BARCALUINE BORE (Government).— Lat. 23° 30', Long. 145° 10'. 
Site nine hundred and fifty-three feet above sea-level ; depth of bore, six hundred 
and ninety-one feet nine inches ; water rises twelve feet four inches above surface in a 
ten-inch pipe at the rate of 175,000 gallons per day ; temperature, 102°; pressure, 17 lb. 
to the square inch ; cost of bore, £775. J 
In his next Annual Report, Mr. Henderson notes : “ This bore has maintained its 
reputation for yielding a large supply of excellent fresh water. Nothing has been done 
since the date of my last report to enable the Department to shut off with safety the 
flow of the water, by means of the screw-plug and valve with which the casing is 
furnished.” Thrown open for bathing purposes with beneficial effects.*

Hardness, 2° 8'. The salts in solution arc chiefly bicavbonates of sodium and potassium. There- 
fore, while the water may be used for domestic purposes, they are unfit for use in irrigation.
