levels towards the junction of the Inangahua and Bnller Rivers. He also 

 made a special report on an antimony lode at Reefton, showing that an out- 

 crop had been found which was about eighteen inches thick, and the reef 

 had been driven on for 150 feet from that point without antimony being 

 found. Heavy lodes of antimony are, however, found in several of the 

 auriferous claims from Rainy Creek to Boatman's, which, in all cases con- 

 taining gold, are treated in the ordinary way for the extraction of this alone, 

 all the antimony and probably much of the gold being thus sluiced away. 

 An examination of the auriferous cements at the head of Lankey's Gully 

 showed that tinstone undoubtedly occurred associated with these in small 

 quantities, but bad weather prevented any attempt being made to trace this 

 back to its parent rock. He visited Langdon's Reef, near Greyrnouth, and 

 reports that the thickness of the reef, at present being worked, is about two 

 feet nine inches, which, being less than it was at the outcrop, shows the lode 

 to be of a bunchy character. 



The outcrops of coal in Coal Creek, Greyrnouth, were also examined, 

 and he reports that two seams of coal 6 feet and 10 feet in thickness re- 

 spectively, occur iu the lease, in which a considerable quantity can be 

 worked level free. In the month of June Mr. McKay paid a visit to the 

 Terawhiti reefs, and reports that the Albion claim possesses a reef of an 

 average thickness of from 18 inches to 2 feet, which has been followed along 

 its strike for a distance of 6 chains, and for a depth of 130 feet. Some 

 assays of quartz from this claim have yielded over 3 ozs. of gold per ton, 

 but the specimen brought by Mr. McKay gave nothing but traces of the 

 precious metal.
