dance of yellow ore (from which brilliant specimens were selected 

 in tetrahedral crystals of considerable size) and was worked to about 

 100 fathoms from the surface. Bodilly's vein varied from one to 

 six feet in width, the ore was yellow, the vein was for the most 

 part poor and hard, and was worked to the depth of about 125 

 fathoms. The load, or substance, of the South and Dunkin's veins, 

 passed through the New Tin vein, which, a little below the latter of 

 them, yielded a considerable quantity of tin, as it did also at about 

 70 fathoms from the surface ; in the intermediate space it likewise 

 yielded tin, with a very small quantity of copper, but was far from 

 rich. It was pursued for about 90 fathoms in depth. In the 

 small vein on the south of Chappie's vein sofne tin was found, but 

 the quantity was not considerable. Chappie's vein varied from one 

 to three feet in width, and yielded yellow copper ore, interspersed 

 with large quantities of iron pyrites. It was worked to about 100 

 fathoms from the surface, as was also the Highburrow vein, which 

 varied from six to twelve feet in width, and yielded both tin and 

 copper, either intermixed or running side by side down the vein : 

 the latter was both yellow and grey, and very abundant. The old 

 vein is very large, and was very productive of tin for about the 

 depth of 45 fathoms from the surface, when it became poor, and 

 was found to contain little else than iron pyrites. But as this 

 vein, during many years, proved immensely rich in copper when 

 passing through Cook's Kitchen mine, which is contiguous to Tin 

 Croft on the west, little doubt is entertained by miners that it 

 will also be found rich in copper at a greater depth than it has 

 hitherto been proved in this mine. To Captain Thomas Teague, 

 of Redruth, an experienced and very intelligent miner, and who 

 during many years has principally conducted the working of Tin 

 Croft mine, I am indebted for the Section. He informed me
