MINING. 289 
§ 218. Siskiyou.—Siskiyou county lies east of Del Norte 
and Klamath, is forty miles wide from north to south, one 
hundred miles long from east to west, and reaches to the 
eastern boundary of the state. It has a population of 7,629, 
the large majority of whom are engaged in mining. The 
mining district is all in the western end of the county, along 
the banks of the Klamath River and its tributaries the Scott 
and Shasta Rivers. The Klamath runs through a deep cafion; 
the Scott and Shasta Rivers have pleasant open valleys, but the 
diggings along their banks are chiefly among the cafions near 
the Klamath. Hydraulic and tunnel claims are rare. There 
are six quartz-mills in the county and fifteen mining-ditches, 
of which last the principal is the Yreka canal, forty miles long, 
bringing water from the head of Shasta River to the town of 
Yreka. In 1859 there were four quartz-mills in the county, 
one of which was at Mugginsville, one in Scott’s valley and 
two in Quartz valley. I have no information about the situa- 
tion of the two built since that time. The principal mining 
towns are Yreka, Scott’s Bar, Hawkinsville, Johnson’s Bar, 
Deadwood, and Cottonwood. 
§ 219. Zrinity and Shasta.—South of the western part of 
Siskiyou and the eastern part of Klamath, lies Trinity county, 
ninety miles long from north to south, and about twenty miles 
wide on an average. The northern part of the county is the 
basin of the Trinity River, and is auriferous. From the county 
A\ssessor’s report for 1860, it is to be inferred that there is not 
a quartzmill or a mining-ditch in the state. The county is 
very mountainous, and most of the mining is done in rugged 
cations along the Trinity River. The chief mining towns are 
Weaverville, Cox’s Bar, Big Bar, Arkansas Flat, Mooney’s 
Flat, and Trinity Centre. 
South of Siskiyou and east of Trinity lies Shasta county, 
which is on an average forty miles wide from north to south, 
and one hundred miles long, reaching to the eastern border of 
the state. There is a rich avriferous district. about twenty 
miles square, in ihe vicinity of the town of Shasta, in the
