of 10°, and has been opened up by a considerable amount of 

 tunnelling. 



In general, the reef varies in thickness from 1 ft. to over 6 fr., 

 its mean width being 3 ft. The foot-wall is generally smooth 

 and fairly defined, the hanging- wall indistinct. As in the Glen- 

 orchy reef, and from the same cause, frequent rolls occur, illus- 

 trated in the section (fig. 8).

The quartz occurs in a seam from 6 in. to 4 ft. thick, the 

 remainder of the lode-formation being composed of soft structure- 

 less pug, graduating into veined and crushed country rock, 

 and crossed by frequent slides. The seam generally follows the 

 foot-wall, but sometimes divides into two, one on each wall. 

 It occasionally crosses from one wall to the other, and a seam 

 may wedge out on one wall, while another comes in on the other 

 wall immediately opposite. 



The Ounce Reef. 



This lies four miles south-east from Macrae's Township, on 

 the left bank of a small stream running into Murphy's Creek. 

 The outcrop of the reef is anticlinal, due to a local rock-fold, 

 and the vein peters out on the limbs of the anticline (fig. 9).

It thus simulates the saddle-reef type of Bendigo, Victoria. 



Several other outcrops in the Macrae's and Mount Highlay 

 districts have been prospected and intermittently worked for 

 gold, but nearly every one that has been developed has been 

 found to carry more or less scheelite. The gold-value of the 

 lodes varies from 4 dwt. to 12 dwt., mostly free-milling.
