is a network of irregular stringers, inclosing much mineralized ande- 
sitic country rock. Distinct walls are lacking, and the ore is taken 
out to a width determined by its value. This is sometimes over 30 
feet. 
The Gold King lode is particularly irregular, and its character led 
almost inevitably to the litigation between the Gold King and Samp- 
son companies, which was wisely settled by the purchase of the latter 
by the former. 
It shows a marked tendenc}^ to split, inclosing large, irregular horses 
of the country rock, and dividing locally into two or more apparently 
distinct lodes of varying dips and strikes. It thus, with our present 
mining laws in force, opened unending possibilities of contention, so 
long as the two mines were under separate ownership. One of the 
most remarkable instances of this tendency seems to be developing 
on the main Gold King level, about 400 feet west of the adit cross- 
cut. Here a large, flat body of ore, continuous with the ore of the 
main Gold King lode, has been followed out for 30 or 40 feet to 
the northwest with a very gentle northwest dip. This ore apparently 
rests upon the top of. a large horse, as in the northern part of the 
stope the dip of the ore is now found to be suddenly increasing. 
Possibly a still more striking case is the relation between the Gold 
King and Davis lodes. It seems very probable that these are not dis- 
tinct, but merely branches of a very large, irregular stringer lead 
separated by a large horse of country rock, in which ease they may 
be expected to come together in dip and strike. 
At the point where it is reached by the adit crosscut (which runs 
nearly north) the Gold King lode is faulted by the so-called "Red 
vein," which has a northwesterly course and dips northeast about 
75°. The horizontal displacement is about 30 feet, the northeast por- 
tion of the Gold King being thrown to the northwest. A supposed 
"bend" in the Gold King lode on the level below is almost certainly 
the same fault. The Red vein contains rhodonite (hence its name), 
which is not found in the Gold King and Davis lodes. It contains no 
ore of value, as far as known. 
The characteristic ore of the Gold King and Davis lodes consists of 
white quartz with abundant pyrite, often showing banding by disposi- 
tion. The pyrite, when massive and nearly free from quartz, is of 
little value in the Gold King lode, but carries gold in the Davis lode. 
The best ore always contains quartz, which may occasionally show 
some free gold. Galena, usually fine granular, occurs in bunches, 
being more abundant in some portions of the lodes than in others. 
As a whole, the ore is low grade, and probably no mine in the quad- 
rangle can set as small nether value for workable ore. 
Extensive preparations are being made for the future working of 
this property. The American tunnel cuts what is thought to be the 
same lode at a vertical distance of several hundred feet below the
