likewise utilized. The almost total absence of "features" from 

 the parish plans; greatly minimizes their value, and for part of the 

 area dealt with, not even parish plans were available. Parts of 

 the plan of County Bourke, for instance, remain to-day as they 

 were first published, unfinished, many years ago, on the 1845-46- 

 surveys. 



(c). The geological formations underlying the surface features- 

 have necessarily been of prime importance, and the Quarter Sheets 

 published by the Victorian Geological Survey have been liberally 

 availed of. In addition, the writer has been kindly supplied by 

 the Survey authorities with copies of the unpublished plans of 

 Moorabool W., Moorabool E., Korweinguboora, Blackwood, Gorong 

 and Darriwill. Further, he has been allowed to make tracings of 

 unpublished quarter sheets 11 S.E. and S.W. The various reports 

 of that department, including boring records, have also been 

 utilized, 



For all this, thanks are due to the Director, Mr. H. Herman, 

 and his officers, especially Mr. W. Baragwanath, of the Ballarat 

 Branch. 



(d). The Military Survey of the Commonwealth has, fortunately, 

 done a great deal of contouring work in this area. The writer has 

 thus had the invaluably assistance of their published sheets, as well 

 as access to all the original field notes of the surveyors, in which 

 matter every assistance was kindly afforded by the officers of that 

 branch; special thanks are due to the chief draughtsman, Lieut. 

 Raisbeck. 



Subsequent to the preparation of the paper, the Commonwealth 

 Military Survey have published a contoured plan of the greater 

 part of this area, on a scale of two miles to the inch. It is on sale 

 as the Ballan-Meredith-Sunbury-Melbourne sheet, and reference to 

 same would help to make clear many points in this paper that it 

 was not possible to illustrate. 



(e). The Railway Department has, during earlier years, accumu- 

 lated much valuable information in the nature of trial railway 

 surveys over various less-known parts of the area, and the writer 

 was allowed to- examine and make full notes from all these old 

 surveys in their offices. 



(f). In the matter of rainfall and water conservation, the Com- 

 monwealth Meteorologist and the State Rivers and Water Supply 

 Commission courteously complied with all requests for information? 

 made to them.
