A MENTAL FORECAST OF A BUSY SCENE. 39 myself how it would appear a few months hence, when all these uninteresting preliminaries were finished. I saw, in mental vision, the crushing-house built of iron and wood; the solid iron pillars supporting the roof, constructed in England and sent out so as to be erected with as little delay as pos­sible. Behind the house, again, upon the bank above, are the stone-crushers, from which the broken quartz is conducted into the stamping machinery by a series of shoots. The ore, the picture shows me, is being rapidly delivered into the stone-crushers along two different inclined tramways ; the one from the north, from the South Indian mines, a mile and three-quarters away; the other from the south, bringing down the Glenrock quartz. Although re­duction will be proceeding under one roof, that roof covers two completely distinct sets of machinery, each consisting of two batteries of ten heads of stamps each. I can therefore imagine them in full work, with the thunder of forty heavy stamps in­cessantly pounding upon their ponderous anvils. Then I could fancy the two powerful turbines, driven by the column of water falling from a height of 120 feet, and capable of working either inde­pendently or together as may be necessary. On the lower platform are the four buddies.
