character of the Carbona. The Carbona then strikes off in 
a N.E. direction, and Jeaves the trawn, which soon resumes 
its original composition. The Carbona*, on the eastern 
side, is enormously larger than on the western side of the 
trawn. 
(w.) At Wheal Providence the eastern flucan heaves the 
Caunter lode 6 feet towards the right-hand at 30 fathoms deep, 
and 10 feet towards the left at 48 and 58 fathoms. 
(v.) At 12 fathoms deep, in Wheal Robert, the cross-course 
heaves the Ore lode 6 feet towards the left-hand, and at 24 
fathoms, 18 feet in the opposite direction. 
(w.) At West Pink the lead vein heaves Carrow’s Gossan 
lode 5 feet towards the left-hand at 25 fathoms deep; but at 
59 fathoms Carrow’s Gossan lode heaves the lead vein 60 
feet towards the right. 
(.) At the Morvah and Zennor Mines the lode and north- 
course twice intersect each other. 
(y.) At 112 fathoms deep, in Great Work, the cross-course 
heaves Wheal Breage lode 1 foot to the left-hand, and at 132 
fathoms simply intersects it; whilst at an intermediate spot 
(122 fathoms) the lode divides the cross-course, although 
it does not heave it. 
(z.) At Trevaskus the lode intersects both the eastern and 
western cross-courses, but it heaves neither of them. 
(aa.) At Wheal Trannack, the cross-course, at 34 fathoms 
deep, is perpendicular, and is heaved 2 feet towards the left- 
hand by the lode; at 64 fathoms it is also perpendicular, and 
there it is simply intersected; whilst at 74 fathoms it dips 
east 84°, and is again heaved by the lode 9 feet towards the 
left-hand. 
(bb.) At the Marazion Mines, Godolphin, and Dolcoath, 
some of the cross-yeins, which do not appear at the surface, 
at certain depths below heave the lodes. 
(cc.) At Relistian, on the other hand, the flucan, from the 
surface to 125 fathoms deep, intersects, and in one spot heaves, 
the lode; but beneath that level it wholly disappears. 
(dd.) At Wheal Buller the cross-veins, which intersect 
some lodes, although cutting them at all depths, do not reach 
to other parallel lodes at very small distances from those in- 
tersected. 
(ce.) At Poldory (United Mines) several small flucans in- 
* In this most interesting spot scme very curious formations of quartz 
have been lately found. They seem as if they had originally inclosed 
hexagonal prisms; and these being removed, there remain cups formed of 
quartz, coated both within and without with small pyramidal crystals of 
the same substance.
