Some of the richest veins indeed rarely show visible gold, while others which contain nuggets arc in other respects very poor. A specimen of calcareous spar from the Waverlcy vein, given to me by the superintendent, seemed to bo of later formation than the quartz, and to have filled a "vug" or cavity; but in a specimen from the Britannia Mine, presented to me by Mr R. G. Fraser of Halifax, a magnesian and ferruginous calc-spar holding gold occurs near the wall of the vein, and is interlaced with thin veinlcts of quartz which are highly «uriferous. Gold also occurs occasionally in the slate forming the wall of the vein, occupying minute crevices in the rock, and I observed at the IMontagu Mine, near the Waverlcy, that gold occurs in thin veins of quartz and mispeckcl, penetrating the slate to some distance from the main vein. At the Montagu Mine the vein worked is from four to eight inches thick, and is enclosed in gray slate nearly vertical, and with strike "W. 5° S. to W. 10° S. Another smaller vein occurs at a distance of fifteen feet; and about five feet from this last the slate gives place to quartzite, which in this vicinity appears to alternate frequently with the slate. No geologist who examines these veins can, I think, doubt their aqueous origin; but different opinions may be entertained as to the pre- cise mode of introduction of the metallic minerals. The facts already stated, in reference to the structure and mode of occurrence of the veins, and the manner in which the gold is associated with the other min- erals present, ap
