Further Notes on South Australia. 

 Another stream of underground water, which I ex- 

 amined during my water explorations in South Australia, was 

 from a catchment on Mount Lofty. This stream, though not 

 artesian, was of interest as showing the grade of the under- 

 ground flowing water. Coming from the range behind 

 Adelaide, it passed thence under that city, towards the 

 sea, and at increasing depths along the line of its flow. 

 The depth at Glen Osmond, on the foot-hills, was 40ft. 

 from the surface ; at Adelaide, 70ft. ; at Kilkenny, nearer 

 the sea, 118ft. ; and under Port Adelaide probably at a 

 greater depth, as a bore made at the port down to 100ft. 

 from the surface did not reach the underground water. 

 It is most probable that this underground water passes 

 under the sea bottom of the Gulf of Saint Vincent, and 

 finds an outlet further seaward. 



A Water-logged Valley in Queensland. 



One of my first studies of the underground waters 

 of Queensland was the large subterranean storage of water 

 on the western side of Rockhampton. This extends to 

 Warren, on the Queensland Central Railway, a distance of 

 18 miles. The water is found at a depth from the surface 

 of about 22ft. As the rise of the surface between the two 

 places just named is 150ft., the slope of the surface of this 

 underground water will be about 8.3ft. per mile, and the 

 water must be a flowing stream. Some years ago I made 

 an examination of this body of water by means of bores,
