but the general returns were small. This declension was pro- 

 baljly in part due to the extraordinary wave of prosperity 

 throu<rhout Victoria, which culminated in the great land boom 

 of 18S8, and which drew jieople from a mining field such as 

 Warrandyte. 



From 1891 to 1900, the yield rose again considerably and 

 almost equalled that of the period 1871-1880. Almost half of 

 the yield came from the Victory Mine from three years" work- 

 ing. 



From 1901 to the middle of 1910, the amount of gold ob- 

 tained was quadruple that of the preceding decade. The yield 

 was almost wholly due to the Caledonia Mine. 



The following table shows the yield from quartz, in decades 

 from October, 1861, to the middle of 1910, together with the 

 tonnage, average yields and values, taken from the official 

 records. 1 



These figures do not include the yields from mullock, quartz, 

 tailings, pyrites, etc., but as some of the returns from these 

 sources include alluvial results, no exact figures can be given. 

 It is quite safe to state however, that the whole would not ex- 

 ceed £1000 in value. 



The results of the working of the two dykes are also not in- 

 eluded. As shown below, the value of the gold obtained from 

 them is £7066. 



Thus according to the official figiu-es the total amount of gold 

 won from quartz and the dykes during the past fifty years 

 amounts to less than £100,000, of which, in round figures, 



1 The fractions of grains have been omitted from the averayfe yields, and the values have 

 been calculated to the neiire.st \ oz. The.se returns include those from the reefs (Lojal 

 Liberal, Growler's and Pride of the Morning'-) a little north of Warrandyte, which are 

 associated with the Main North Anticline.
