558 THE GEOLOGY OF THE WARRUMBUNGLE MOUNTAINS, 



November), so that the observations here recorded represent 

 field-work occupying a period of nearly four months. 



During my field-work I derived much information about the 

 country and cordial assistance from men stationed in the district. 

 To Mr. Goodridge, Licensed Surveyor, I am particularly indebted 

 for his never-failing courtesy and help. Dr. F. Failes of Coona- 

 barabran, Mr. May-Steers (Stock Inspector), Messrs. John Knight,. 

 Senr., and Alfred Knight of Tannabar Station, Mr. Lawrence 

 Brown of Tundebrine Station, Mr. J. Draper (Tundebrine), Mr. 

 Goldfinch of Gowang, Mr. Wright (Road Inspector), and many 

 others have rendered me valuable help. To Mr. A. Wallace I 

 am indebted for his cheerful company on my first trip through 

 the mountains. On my second trip I was accompanied by my 

 brother, Mr. Thor Jensen, L.S. 



Owing to the rough nature of the country, it was necessary to 

 work this district b}'- camping out in various places to which 

 access could be attained with a vehicle, and making excursions 

 on foot from the camps in all directions. During the work I 

 have been camped at the following places : — Coonabarabran, 

 Riversdale, Tannabar, Gowang, Uargon Creek, Tooraweanah, 

 Tundebrine, Tenandra, Goorianawa, Bugaldi, Upper Bugaldi 

 Creek and Yarraman. By working from these localities it was 

 found possible to visit all the most important peaks of the group 

 and to acquire a good idea of its geological structure. 



Work of a detailed nature has never been done in the district 

 before, with the exception of Professor T. W. Edge worth David's 

 description of the diatomaceous earth and tuff-beds at Wandi- 

 allabah (Wantialable ?) Creek.* The Rev. J. M. Curran has 

 visited the district on several occasions, but has not published 

 anything about it. Mr. Pittman and officers of the Geological 

 Survey have made hurried trips to special localities in the region 

 to report on mining claims, but have done no detailed geological 

 work. To Sydney people the district is only known through the 

 photographic zeal of His Honor, Judge Docker, who has done
