The alluvial digging.s, Imwrvei-, were soon exhausted, and after 

 about the year 1880, this source of gold became unimportant. 



Production : — In compiling statistics of gold production, tlie 

 author has made considerable use of the Quarterly Reports of the 

 Mining Surveyors and Registrars from 1859 to 1891, and of the 

 Annual Reports of the Mines Department from 1891 to 1011. As 

 the latter publication gives only isolated rich yields, and not 

 the complete returns, for the greater part of the above period, any 

 statistics so obtained are necessarily incomplete. The records show 

 that up to 1890, nearly 25,000 ozs. of gold were won from the 

 ><juartz reefs, distributed thus in round figures : — 



Panton Hills 9000 ozs. 



One Tree Hill 7500 ozs. 



Yow Yow 7500 ozs. 



Valued at £4 an ounce; this is equivalent to nearly £100,000 worth 

 of gold. Two thousand ounces is a very conservative estimate for 

 the production between 1890 and 1912. so that the total yield from 

 the field, exclusive of the yield from the alluvial, is well above 

 £100,000. No complete returns of the gold obtained from alluvial 

 .sources are possible, as the records are far from being complete. 



/ B.—One Tree Hill. 



The productive reefs at One Tree Hill \\\n parallel, and at short 

 •distances apart, all outcropping at the top of the hill, within u 

 width of 200 yards. The strike of these reefs varies from N. 15^ E. 

 to N. ^Oo E., corresponding closely to the strike of the contiguous 

 sedimenrv which are here chiefly brown and white sandstones, in 

 places indurated and changed to quartzite. At the south end of 

 the hill one or two small quartz reefs strike across the country rock, 

 but as far as the author is aware very little gold has been obtained 

 from them. The most important reefs worked at One Tree Hill 

 aie from east to west, the Buck, Moonlight, S^vedish, and the Home- 

 ward Bound. Further east than the Buck line are one or two 

 •other reefs, the most important of which is the Victoria reef. It 

 was prospected in the late fifties and early sixties, but, according 

 to the records, little gold was obtained. All these reefs dip at fairly 

 «teep angles, frequently approaching the vertical, and cut across 

 the strata in depth. In this respect they resemble the reefs at 

 Warrandyte. The Buck line of reef has been extensively developed 

 by means of a tunnel driven from Fern Tree Gidly. This tunnel
