596 Journal of Agriculture. Victoria. [10 Oct., 1912. 



Occurrence. — Tertiary limestone exposed in a small quarry, and from 

 the general appearance of the country there appears to be a very consider- 

 able amount of similar material to that submitted for analysis. 



Economic. — Its position is convenient for transport, being about i mile 

 from the railway, and the quality of limestone as collected for analysis 

 is excellent,

(20) Wombat Creek. 



Locality. — On Wombat Creek, about 2 miles west of the Wombat- 

 Mitta River junction, parish of Tongaro, in the county of Bogong. 



Occurrence. — Blue to grey crystalline lime.stone bands of Silurian age. 

 The area is extensive. 



Economic. — The values of Ca CO3 should be high, and somewhat 

 similar to the other crystalline Silurian limestones as at Mansfield, &c. 

 The locality is in rough mountain country, and too far from railway com- 

 munication at present to be of commercial value. 



(21) Batesford. 

 Locality. — Just east of the Dog Rocks, on the Moorarbool River, and 

 about I mile south-east of the Batesford bridge, parish of Gheringhap, 

 in the county of Grant. 



Occurrence. — Yellow to reddish limestone of Tertiary age. A hilt 

 section shows —

Economic. — The Upper Quarry shows a fairly hard limestone passing^ 

 upward into a friable limestone, making about 45 feet in all. 



The Dryden, or Filter Quarry, is about three-quarters of a mile lower 

 down the Moorarbool, and here the deposits are very extensive, and are 

 being worked by P. McCann and Sons, of Fyansford, for cement pur- 

 poses, &c. The beds vary, being at one place 22 feet vertical of pure 

 white, friable limestone, but generally less.
