On the Murine Rods underlying Warrnaruhool. 99 



consist of alternate layers of porous sandstones and gravels, 

 and impermeable clays. 



The rain which falls on the land suiface for a distance of 

 90 miles inland, is collected and conducted to the coast Ijy 

 these natural drains. No materials more suited to the 

 purpose of artesian wells ai-e known to occur. On the coast, 

 the sea serves to dam back the fresh waters until they stand 

 permanently a few feet above sea level at a short distance 

 inland. Along the shore line the fresh water wells out in 

 the sands and through rock fissures as spring water. 



Near Cape Bridgewater, and a mile oi" so from the coast, a 

 powerful spring wells up to the surftice, and its fresh water 

 was used largely by whalers a few years ago as a convenient 

 source from which to fill their water tanks whilst keeping 

 on the fishing grounds. When the boring rod entered the 

 gi-een-sand at 358 feet (200 feet below sea level), the water 

 rose 225 feet in the tube, soft and fresh in quality. 



It seems to me that all the conditions exist here for a 

 good artesian water supply. As the bore goes deeper, it 

 will tap other supplies wliich come from sources which are 

 further away, and which start at greater altitudes. The 

 hydrostatic pressui'e in such cases will increase, and probably 

 will suffice to carry to the surface a large supply of good 

 water. 



The celebrated artesian well of Grenelle, near Paris, taps 

 its water supply in just such a green-sand bed as that which 

 lies beneath the town of Warrnambool. It would be a pity 

 therefore, were the bore not to be sunk until the requisite 

 water supply is obtained.
