elevator, pump, derrick, and a sawmill. It i.s planned to continue 
the pit upstream until sufficient grade is secured for ground sluicing. 
When the stream is confined the current will doubtless be able to carry 
off the tailings (PL VII). 
Mix claim. — On this property work is being done on a gravel bench 
from 20 to 80 feet wide and 8 feet deep, occurring on both sides of 
the creek about 60 feet above the stream. The valley widens at the 
lower part of the claim, and a broad bed of creek gravels has been 
deposited (PI. VIII, A). The claim was leased by a mining company 
during the summer of 1901, but the operations did not prove success- 
ful and no further developments have been undertaken. At present 
part of the upper bench is leased to a miner, who has recovered many 
nuggets of gold. 
Finley claim. — The deposit here is on the same bench as the one 
below. The gravel bed is 100 feet wide, 6 to 10 feet deep, and 80 feet 
above the creek. In 1901 a large production was reported from this 
property, but it is not operated at present (PI. VIII, B; iig. 3).

On the Legal Tender fraction, an extension of the Finley bench, a 
good section of the channel with the gravel deposit is exposed. One 
man working with a 6-foot sluice box was making good Avages. 
Following this is the Wiley claim, which corresponds in character 
to the Finley claim; no development work has been done on the 
bench at this place. 
m'kinley creek. 
At the junction of McKinley and Porcupine creeks the first location 
is the Lewis claim, joining the Wiley property and extending 800 feet 
along the Porcupine to the forks, thence 500 feet up McKinley Creek. 
A hundred paces above the forks there is a waterfall about 60 feet 
high, known as the McKinley Falls, below which good values have 
been found. 
Chisholm claim. — The next claims in succession are the Chisholm 
and Hall properties, owned by the United Gold Mining Company. 
On the former of these, where the placer deposit is being exten-
