Colonial Exhibition, 1886. 
bria mine, the paid up capital of which in 1884 was but 
£1,837 I0 ? ^ th e beginning of December 1885 declared 
dividends amounting to £48,825. Another mine, bought 
4 years ago for £250, has, with a capital (including pur- 
chase money) of £946, won 41,473 ounces of bar gold, 
worth £114,136, yielding to the shareholders £60,750 
in dividends. 
The New Zealand gold-bearing alluvia are spread over 
the country in beds often several hundred feet thick, but 
gold is also obtained by dredging sand and gravel from 
the bottom of existing rivers. The dredgers are w r orked 
by steam or by paddle-wheels driven by the force of the 
current. We in British Guiana might take a hint and 
ascertain whether the deposits in our river beds are 
auriferous ; if so, our tidal streams would, as in New 
Zealand, afford motive power for dredgers. 
Recent sea beaches in New Zealand, formed or added 
to by auriferous sand carried down by the rivers, are 
also worked, yielding if oz. to the ton as gathered, and 
4 oz. 4 dwts. when concentrated. 
The Transvaal also produces gold in its eastern parts. 
The quartz reefs near Barberton vary in thickness 
from 4 or 5 inches to 2 feet 6 inches, and produce 1 to 
5 ounces per ton ; 2,875 tons of this quartz yielded 5,369 
ounces of gold or 1 oz. 17 dwts. to the ton. In 1885, 
52,228 ounces were exported through Natal alone. 
Mr. FOSTER in summing up remarks that the gold- 
producing capabilities ot Australia, New Zealand and 
Canada are very great ; that although the shallow, alluvial 
diggings of Australia, which could be worked without 
capital, are exhausted in some places, " deep leads" and 
quartz reef abound, only waiting for capital to develop
