tube down at the Springs, where a crack occurs. The bottom 

 seems to be entirely composed of (juartz shingle, and, as the 

 course of this lava-flow has been along a basin, into which, 

 for many miles, quartz reefs run ; in the event of the 

 bottom under that i-iver bed being i-eached, I should say 

 that the best deep lead yet discovered in Australia would be 

 found there. 



The deep lead at Gympie and this one could be easily 

 bottomed, at a comparatively small expense, by using iron 

 cylinders and compressed air, similar to tliose used by bridge 

 engineers. 



The alluvial ground on the Hodgkinson and Palmer, and 

 several other fields, always present a knobbly appearance to a 

 bird's eye view, or when seen from the top of a high mountain, 

 such as would be produced b}'^ a layer of thin paste spread over 

 a pie dish filled with plums, which correctly illustrates the 

 appeai-ance of the Hodgkinson from the top of Mount M'Can, 

 and the Palmer, from the top of the Knobby, on the Granite 

 Range, near Byerston. 



These remarks have been compiled from old note books, 

 and mainly with the object of creating inquiry and discussion, so 

 as to assist in reducing mining enterprise to an exact science, 

 and so prevent the enormous waste of capital at present 

 employed in searching for minerals. 



There is great difficulty in obtaining any information as to 

 the past or intended Avorking of any of the well known reefs 

 that would be of any advantage to scientific mining. In most 

 districts of the colony there are many individuals well versed in 

 geology, but as to the mechanics of geology as bearing on the 

 commercial aspect of the question, there is no information to be 

 obtained.
