Mr. Slee, F.G.S., Superintendent of Drills, in a Report to 

 the Department of Mines,* states with regard to the Balli- 

 nore bore as follows : — " That at a depth of 540 feet the 

 drill passed through a seam of coal 5 feet 2 inches thick, 

 and while boring for a second seam of coal 10 feet below the 

 first, artesian water commenced to flow to the surface, and 

 is now flowing at the rate of 1000 gallons per hour, flowing 

 through tubing 30 feet above the surface, and higher 

 if required. The water when coming up through the bore- 

 hole contains a great deal of gas, and has a taste somewhat 

 similar to the German Seltzer water." 



The Rock Flat Mineral Spring is situated about JO miles 

 to the S.E. of Cooma, and occurs in close proximity to the 

 western banks of Rock Flat, in the Parish of Dangeling, 

 County of Beresford. For a description of this spring and 

 the geological formation of the surrounding district I refer 

 you to a paper by Mr. Geological Surveyor Anderson, 

 entitled " On the Mineral Spring at Rock Flat, near 

 Cooma."
