which form the opposite Walls of Cross-veins. 375 
latter 15 feet. In the same mine the Great flucan simply in- 
tersects the same elvan-course and its off-shoots, whilst it 
heaves the south lode 100 feet towards the right-hand. 
(f.) At Wheal Unity Wood the flucan simply intersects 
the elvan-course, whilst it heaves Pits-anvollar lode 21 feet, 
Trefusis lode 12 feet, and the Little ore lode from 30 to 36 
feet, all towards the left-hand. The elvan and all three lodes 
dip northwards. 
(g.) At Wheal Prudence the elvan-course and the north 
lode dip to the north, and the south lode towards the south. 
The cross-course heaves all of them towards the right-hand, 
the elvan 30 feet, the north lode 9 feet, and the south lode a 
distance varying from 18 to 30 feet at different levels. 
(z.) At Polberrow the eastern cross-course heaves the Pye 
and North Seal Hole lodes each 9 feet, and the South House 
and Great Gossan lodes each 12 feet: the first two dip to- 
wards the north, and the two last towards the south, and all 
of them at different angles,—nevertheless they are all heaved 
towards the right-hand. 
(z.) In the western part of the Consolidated Mines Tiddy’s 
cross-course simply intersects an elvan-course which dips 
north-west, and also Glover’s branch which dips towards the 
south, with a very variable inclination; but it heaves Michell’s 
lode, which also dips southward, 3 feet towards the right- 
hand; and Paul’s lode, which dips towards the north, from 
15 to 18 feet in the same direction. In the corresponding 
part of the United Mines (south of the Consolidated) the same 
cross-course heaves the Old lode 8 feet towards the right-hand 
at one level, and 6 feet to the left at another; it also heaves 
the Mundic lode, which dips northward, 9 feet towards the 
right-hand, and Gellard’s north and south lodes, which have 
a southerly dip, each 6 feet towards the left. 
(j-) The western flucan, in East Wheal Damsel, heaves 
both lodes 72 feet towards the right-hand, although they dip 
in opposite directions; whilst Stevens’s flucan, at different 
levels, heaves them to different distances, but always towards 
the left-hand. 
(<.) At Wheal Union, the trawn, at 43 fathoms deep, is in 
three veins, which, above and below that level, are united into 
one; but, whether separate or united, at their intersections 
Wheal Gwens lode is always heaved towards the right-hand, 
Where the trawn is single at one level the heave is 36 ft., at the 
next 25 ft., and at the third, where it divides, one vein heaves 
the lode 1:5 foot, the second 8 ft., and the third 24 f. The 
western trawn heaves the same lode 6 feet inthe same direction,
