clay gouge and crushed quartz frequently enter the lode obliquely 
from the southwest Some of the richest bunches of ore said to have 
been found were where they intersect the main lode. The best ore 
usually occurs in the steeper portions of the vein. The pay shoots 
are stated to lie flat, one above another, and to extend diagonally 
across the lode from uorthwest to southeast. 
The richest ore is invariably found in the shattered and stained 
parts of the lode, generally alongside a soft gouge of crushed and 
decomposed andesite. The gold usually occurs free and very finely 
disseminated. When visible, i1 is em- 
bedded solidly in the unpromising-look- 
ing vitreous quartz, although Mr. Ros- 
coe Wheeler, the assayer a1 the mine, 
informed me that he had found one 
piece of gold in a fracture plane in the 
quartz. In the more recent workings, 
below the 300 level, the vein is, as a 
whole, less shattered and stained. Even 
at the 800 level, however, portions of 
the lode exhibit the character above de- 
scribed, accompanied by clay seams. 
and such portions are always rich. On 
this level the vein is somel imes 10 to 12 
feel wide, with -2 to 3 feet of galena ore 
on the foot wall, the latter ore being 
more abundant here than in the upper 
levels. 
The description thus far has been of 
the main Tomboy lode. There remain 
to be described the Iron lode and its 
relation to the Tomboy. The two lodes 
are nearly parallel in strike, the Iron 
vein having a slightly more westerly 
course than the Tomboy, which is about 
N. 40° W. But the Tomboy lode dips 
to the southwest, whereas the Iron 
vein dips northeast, As a consequence of this diversity of dip 
the two veins intersect, so that the Iron vein, which above the 300 
level was encountered on the northwest side of the Tomboy, on the 
lower levels is found on the northeast side. Near the main adit this 
intersect ion takes place at about the 300-foot level, but the line is not 
horizontal. The slight difference in strike of the two lodes gives their 
intersection a pitch to the northwest of about 6° from the horizontal. 
The intersection in vertical plane is shown in the accompanying cross 
sections (figs. 14 and 15), drawn from notes of surveys made by 
Mr. John Herron. The relation of these lodes is such that at each
