	the structure and richness of their lodes, have been, and are being, operated upon, at successive intervals of about a quarter of a mile, to the west. These systems are known as the Browning's Luck line and the Bristol line. At the Lord Nelson mine I was granted every facility for inspection by the general manager, Mr. Z. Lane, Sen. It soon became apparent to me that the company had opened an extensive "favoured situation," pretty well on its highest part, as it pitched away south at an angle from the vertical of about 22°, and with an underlay to the west of about 45°. It had been formed on the western side of an anticlinal arch, and the weather of ages had brought the surface line down to a point near its higher part. The efforts of small mining concerns had located and followed it down to comparatively shallow levels from a hill immediately north of the present mine, and the Lord Nelson Company then took charge of amalgamated areas for mining at greater depths. There are 30,000 shares in the company, and but !)d. per share has been called in. The proceeds of receipts from this source, with £375 as share of flotation receipts—in all £l,720—is the total of cash, other than from the mine, that has been used by the company, and the returns to date show 180,410 ozs. 4 dwts. of smelted gold from about 320,000 tons of stone, and £5 12s. yd. per share paid in dividends. The ore is treated by a 40-head mill, with copper plates, Halley's tables, blanket tables, cyaniding, and chlorination of pyrites. The lode masses present all the features associated with the structure of the Pyrenees ore lodes. The "gold situation " owes its existence apparently to pressure from the north

	on the corrugations of the strata, and it is in a belt of gold-slate country having many lines of underground drainage from the slate feeding into it. The dyke material is prominent, in parts showing as a "horse," dividing " makes " of stone, from 4 to 10 feet in width. On the hanging-wall side of the lode mass— the latter has a width of about 30 feet in parts —the strain which resulted in forming the receptacle for the lode, caused the hanging-wall of the main lode to take a bow shape out into the western country. Around and within this bow line is a big lode of golden q uartz, and a thick sheet of dyke material, in the form of what the miners call a. " horse," divides it from another wide " make " of gold-bearing stone on the foot-wall side of the whole formation. At other points, almost vertical winglike " makes " of quartz go west from the main formation, and " feather " out, as most cracks radiating from a bend do. In fact, this favoured situation.
