For instance, a lesson in tracing the lode in a grass covered country was taught me many years ago by an old prospector who had struck good gold in the reef at a point some distance to the east of what had been considered the true course. I asked him why he had opened the ground at that particular place. Said he, “Some folks don’t use their eyes. You stand here and look towards that claim on the rise where the reef was last struck. Now, don’t you see there is almost a track betwixt here and there where the grass and herbage is more withered than on either side? Why? Well, because the hard quartz lode is close to the surface all the way, and there is no great depth of soil to hold the moisture and make the grass grow.” I have found this simple lesson in practical prospecting of use since. But the strike or course of a quartz reef is more often indicated by outcrops, either of the silica itself or ironstone “blows,” as the miners call them, but the term is a misnomer, as it argues the easily disproved igneous theory of veins of ejection, meaning thereby that the quartz with its metalliferous contents was thrown out in a molten state from the interior of the earth. This has in no case occurred, and the theory is an impossible one. True lodes are veins of injection formed by the infiltration of silicated waters carrying the metals also in solution. This water filled the fissures caused either by the cooling of the earth’s crust, or formed by sudden upheavals of the igneous rocks. Sometimes in alluvial ground the trend of the reef will be revealed by a track of quartz fragments, more or less thickly distributed on the surface and through the superincumbent soil. Follow these, and at some point, if the lode be continuous, a portion of its solid mass will generally be found to protrude and can then again be prospected. There is no rule as to the trend or strike of lodes, except that a greater number are found taking a northerly and southerly course than one which is easterly and westerly. At all events, such is the case in Australia, but it cannot be said that either has the advantage in being more productive. Some of the richest mines in Australasia have been in lodes running easterly and westerly, while gold, tin, and copper, in great quantity and of high percentage to the ton, have been got in such mines as Mount Morgan, Mount Bischoff, and the Burra, which contain no lodes properly so-called. Mount Morgan is the richest and most productive gold mine in Australasia and amongst the best in the world. Its yield for 1895 was 128,699 oz. of gold, valued at £528,700. Dividends paid in 1895, £300,000. This mine was opened in 1886. Up to May 31, 1897, the total yield was 1,631,981 ozs. of gold, sold at £6,712,187, from which £4,400,000 have been paid in dividends. (See _Mining Journal_, for Oct. 9, 1897). Mount Morgan shareholders have, in other words, divided over 43½ tons of standard gold.
