The above figures give an average yield of 7 dwts. of gold per 

 ton of ore for an average width of 5 inches. 



The second shaft (fig. 2), partially cleared by Mr. Morris contains 

 a somewhat thicker, but still very small, ore- 

 body ; it has, as in the previous case, been 

 worked to a considerable extent by the natives, who burrowed alono- 

 the vein in various directions. Samples were taken at three points, 

 but gave only traces of gold.
