“ A good supply of water was struck at ninety feet, in sandstone, and it rose to 
about fifteen feet from the surface.”* A stronger supply of water was met with at a 
depth of fifteen hundred and thirty-five feet, in sandstone, which, without doubt, w'as 
artesian, and as it flowed over the casing it was noticed to be accompanied by a supply 
of inflammable gas. When the bore was about seventeen hundred and seven feet deep, 
the flow reached its maximum, the measurements made indicating that the discharge 
registered two hundred gallons in thirty-five minutes at a height of three feet nine 
inches above the natural surface.”f 
Prom Mr. Henderson’s Report, it appears further that the iunction of the base 
of the Ipswich Pormatioit with the underlying talc- schists was met with at the depth 
of sixteen hundred and eighty feet. The bore was continued in the latter for a further 
depth of ninety feet. Mr. Henry Gr. Stokes, of Brisbane, informed me that he 
recognised the ashy sandstone at the base of the Ipswich Beds in the debris from the 
bore. 
The Report of Mr. Robert Mar, P.C.S., Government Analyst, on the water of the 
bore (dated 4th October, 18S9), is as follows : — 
“ Total dissolved solids

“ The dissolved solids consist chiefly of chlorides and carbonates of sodium and 
potassium, together with a smaller quantity of carbonate of calcium and a trace of 
sulphate of potassium. 
“ A small quantity of gas was in the bottle containing the sample of water. This 
I tested, and found it to be carburetted hydrogen. 
“The water is unfit for domestic use, and indeed, in its present condition, could 
not be advantageously used for any purpose, but by proper treatment it could be made 
fit for the purpose of irrigation.” 
On the coal from the Bore, Mr. Mar reported (Brisbane Courier, 6th July, 
1889) the following analysis : — AV^ater, 0-65 ; coke, 64'15 ; carbon, hydrogen, oxygen, 
nitrogen, and sulphur, 75-4 ; ash, 24-6 ; specific gravity, 1-55. 
Near the Albion, a fine white sandstone, similar to that of Goodna, is worked 
for building ])urposos in Petrie’s Quarry. Here there is the following section ; +
