Occurrence. I'Ik-it aif 3 acres ot blue dense limestone with small 

 •calcite veins. These limestone areas occur in Silurian formations, and 

 they are fairly extensive, one being said to be 300 feet in length and 50 

 feet wide. 



Economic - This limestone has been worked in a small way from time 

 to time, and yields an excellent lime. It is very similar to the Lilydale 

 limestone, and is of value both for agricultural and building purpcses.

(4) Tyers River, Gippsland. 



Locality. — Tyers River. 8 miles from the Traralgon railwav station, 

 in a deep gully emptying into the Tyers River. 



Occurrence. — Grey, dense limestone, seamed with small calcite veins, 

 and occurring in Silurian strata. There is a large formation of the lime- 

 stone, which shows for 100 yards in length along the gully, and for a 

 considerable height up either bank. 



Economic. — It appears to be a tirst class limestone, and the analyses 

 made by the late J. Cosmo Xewbery. F.G.S.. show that it is of high 

 •(juality.

(5) Thompson River. 

 Locality. — Thompson Ri\er. between Walhalla and Toongabbie. and 

 about 10 miles in a westerly direction from Toongabbie. 



Occurrence. — Several small areas occur on the Thompson River, east 

 of the Deep Creek junction, and one on Deep Creek is se\-eral chains long 

 and 200 feet high. Another small outcrop occurs nearer Walhalla, and 

 •close to the copper mine area. All are of Silurian age, and occur as a 

 dense, compact limestone. 



Limestone. — These deposits of lime.stone would be suitable for building 

 or agricultural purposes.
