INTRODUCTORY. 



The Mutooroo Pastoral Company has recently put down 

 several trial bores on its property, situated near the intersec- 

 tion of 140° meridian of east longitude and 33° parallel of 

 south latitude, a little to the south of Lilydale sheep-station, 

 and about forty-two miles to the south-east of Yunta railway 

 station. By the courtesy of Mr. L. Keith Ward, B.A., B.E., 

 Government Geologist, my attention was called to these sink- 

 ings, and a small amount of fossiliferous material taken there- 

 from was placed in my hands for examination. The above 

 company, through Mr. Ward, has also supplied information 

 as to the strata passed through, based on the log kept by 

 Messrs. Johnstone Bros., who were the contractors for the 

 work. 



In the map kindly supplied by Mr. Ward, and reproduced 

 on the opposite page, the sites of the two bores are indicated.
