through different stages of treatment by gravitation, although the character of the country is 
specially adapted for the erection of crushing-plants. The slopes of the terraces and hills adjoining 
the valleys are admirably suitable for the erection of plants. Where the stone taken from the 
mines can be emptied direct on to a grizzly, and what does not pass through goes down to a rock- 
breaker, where the ore is reduced to about lin. in diameter and falls into a hopper, which in turn 
feeds the ore-feeders; and on the lower side of thg stamping-battery there should be sufficient 
elevation to admit of tables, concentrators, vats, and sumps, so that the ore in its different stages of 
manipulation may pass down from the time it is emptied on to the grizzly until the gold produce is 
ready for melting. 
The principal assays in connection with the mines in the Eeefton district are made by 
Mr. Aitken, instructor of the School of Mines. Many of these assays show that there is a great 
loss in gold. The following statement shows the results of some of the assays and tests made :—

There is every facility for working the mines and machinery in this district. There is an abun¬ 
dance of mining-timber on all the different claims. There are large areas containing coal of an 
excellent character for fuel in close proximity to the mines, while an abundant w'ater-supply can be 
obtained as a motive-power to work machinery, besides the fact that there is scarcely any water to 
contend with in working the mines. 
The fact that no pumping-machinery has ever been required demonstrates fully this statement. 
The country is well opened up by dray-roads and horse-tracks, and the Township of Eeefton being 
connected by railway with Greymouth the transit of goods and machinery from a seaport is accom¬ 
plished at a comparatively low cost. With all these advantages quartz-mining in the Eeefton 
district, if carried on in an intelligent manner, should be a large field for the profitable investment 
of capital in mining enterprises.
