TAMBO BORE (aovernment).— Bat. 24° 50', Long. 140° 15'. 
Deptli, 1,002 foot ; water overflows at the rate of 200,000 eiallotis per flay ; tem- 
perature, 98° ; pressure, 12 lb. to the square inch.* * * § In his report Mr. Hcnflerson states ; 
“ On 10th September [1888] good, water was tapped in sandstone, and a larger supply of 
excellent fresh water was struck at nine hundred and ten feet ; at 1,002 feet drilling 
Was stopped. An improved screw-plug and stop-valve have been fitted to the inner 
string of casing, by which means the flow of water is stopped or otherwise controlled 
at pleasure. G-enerally stated, the bore was sunk in sandstone and blue clay shales of 
the Cretaceous Formation. Up to the 30th June [1889] the expenditure on this bore 
was £1,514 11s. 2d., including £330 12s. lid. for transport of boring plant and casing, 
and £176 18s. for casing.”

TAMBO STATION, No. 2 BORE (Private). 
Water flowing at the rate of 15,000 gallons per day ; depth not stated ; boring 
continued.! 
LANSDOWNE BORE (Private).— Lat 25° 8', Long. 146° 13'. 
Depth, 2,485 feet ; water rises to within seventeen feet of surface.! 
GRIFFITH’S BORE, ten miles east of Muttaburra.— Lat 22° 37', Long. 144° 32'. 
Depth, two hundred and ninety-three feet. The prevailing strata were fine- 
grained grey sandstones, with some grey shales similar to those in the Aramac Well. 
Specimens of Inoceramus, &c., were obtained at two hundred and seventy-four feet.§ 
ARAMAC.— Lat. 23°, Long. 145° 15'. 
The “ Town Well,” Aramac, was sunk to the depth of three hundred feet, in or 
before 1885. A section of the strata met with has already been given (p. 405). 
The shaft was five feet by three feet. Salt water was struck at forty-seven feet, and 
Diadc five feet in twenty-four hours for some time, but in October, 1885, had diminished 
to three feet. A trifling amount of fresh water was met with at ninety-eight feet. 
Artesian water has been met with on Aramac Eun in two private bores. Ho. 1, 
six hundred and fifty feet deep, yields 2,000,000, and Ho. 2, 1,011 feet deep, yields 
b)*750,000 gallons of overflowing water daily. The temperature of the water is 81° in the 
case of Ho. 1 Bore, and 99° in the case of Ho. 2. The pressure per square inch is — 
^o. 1, 25 lb.; Ho. 2, 39 Ib.f 
The following items of information regarding wells in the Aramac District were 
^applied to me in October, 1885, by Mr. William Forsyth : — 
(1.) Aramac Run, eight miles above Aramac. — Boro, one hundred feet deep ; no 
^ater; strata as in Aramac Well.
