MITCHELL BORE (Governm-ont).— Lat. 2G° 35', Long. 147° 50'. 
A bore was sunk hero for the Eailway Department in 1885, two hundred yards 
west of the station. I was informed by Mr. John Falconer, who was in charge of 
the bore, that the section showed one hundred and eighty-eight feet of blue shales 
beneath twenty feet of drift. Water was met with at two hundred and eight feet in 
S' “ sandv drift ” beneath the shale.s, and rose to nine feet from the surface. On the 
3rd October, 1885, 1 saw it standing twenty-eight feet from the surface. The water 
■Would supply, by pumping, eight hundred to 1,000 gallons per day. The site of the 
horo is 1,101 feet above sea-level. 
BURE:N’DA bore (Private).— Lat. 2.5° 57', Long. 14G" 50'. 
Depth, 1,900 feet; water rises to within thirty feet of surface. 
BOLLON OR SIXTY-FIVE MILE BORE (Government).— Lat. 28° 3', Long. 147° 55'. 
This bore is situated about sixty-five miles from St. George, on the road to 
Cunnamulla. In July, 1891, the depth of 1,810 feet had been attained, and water was 
overflowing at the rate of 30,000 gallons per day. Strata Alluvium, clay, sand, 
pipeclay, limestone, dark and grey-coloured clay,' shales, and sandstones of various 
texture, intorstratified in irregular order, the last stratum being coarse grey sandstone.* 
I am informed (21st September, 1891) that the bore has been stopped at 2,362 
feet, the overflow being about 180,000 gallons per day, at a temperature of 125°. 
CUNNAMULLA BORE (Government).— Lat. 28° 5', Long. 14,5° 40'. 
“ In February [1889] a supply of artesian water was struck at nine hundred and 
seventy-five feet, but boring operations wore continued in the hope of striking a larger 
supply. As boring was continued the flow increased, until, on the 21st of February, a 
supply of 22,500 gallons per hour [equal to 540,000 gallons per day] of excellent fresh 
Water was tapped at a depth of 1,402 feet. Its temperature is 106° F., and its pressure 
is fully 185 lb. per square inch at the surface. On completion of boring operations the six- 
iuch casing was fitted with a recessed screw-plug and stop-valve, by means of which the 
flow of water is controlled, and at pleasure supplied to cousumers. The cost of this bore,
