estimates that the percentages yielded by the principal and 

 other sources of supply were as follow : — 



Per cent. 



Mexico and South America 31 - 5 



United States 197 



Australasia IV -8 



Russia 12'0 



Other countries 19'0 



Total 100-0 



According to a report furnished to the British House of 

 Commons, however, the gold produced between 1855 and 

 1875, presents a marked difference in the percentage for 

 various countries, viz.: — 



Per Cent. 



United States 



42-43 



Australasia 



36-95 



Russia 



15-08 



Mexico and South America 



3-39 



Other countries 



2-15 



Total 



100-00 



It would appear from the latter statement, therefore, that 

 during the last thirty years the United States and Australasia 

 together have produced 79'38 percent, of the world's supply 

 of gold. 



Mr. Hayter estimates that the proportion of gold derived 

 from quartz and alluvial in Victoria for the years 1883 and 

 1884 c was — 



Quartz, GO per cent. 



Alluvial, 40 per cent. 



In Tasmania I find, from an analysis of the latest 

 statistical records, that between 1866 and 1885 the total 

 quantity of gold produced from quartz and alluvial was as 

 follows : — 



ozs. Per cent. 



Quartz 253,630 or 67'04 



Alluvial 124,732 or 32'96 



Total 378,368 or lOO'OO
