PACIFIC SALMON FISHERIES. 37 
keeping its southerly course into Humboldt County, where it forms 
a junction with the Trinity River, and thence its course is directed 
to the northwest until it reaches the Pacific Ocean. 
The Klamath River is important as a salmon stream because it has 
both a spring and fall run of salmon. In 1888 a cannery was estab- 
lished at Requa, at the mouth, and this has been operated occasion- 
ally ever since. The pickling of salmon has been done here for a 
number of years. Some years part of the catch has been shipped 
fresh to the cannery on Smith River or to the Rogue River (Oreg.) 
cannery. Since 1908 the cannery has been operated continuously by 
the Klamath River Packers Association. 
Humboldt Bay and tributaries.—The shore line of Humboldt County 
is bold and high, except in the vicinity of Humboldt Bay, where it 
is rather flat. The latter is the only harbor along the county shore, 
and it is quite difficult of access, owing to the bar at the entrance, 
upon which the sea breaks quite heavily. The bay is about 12 miles 
long and about 3 miles wide. Mad River, which has its rise in the 
lower part of Trinity County, runs in a northwesterly direction, then 
makes a sharp turn and enters the bay from the north side. Eel 
River, which has its rise in Lake County, far to the southeast, runs in 
a northwesterly direction and enters the bay at its southern extrem- 
ity. Small railroads running south from Eureka traverse the shores 
of both rivers for some miles. A railroad now runs from the north 
side of San Francisco Bay to Eureka, and it has aided very materially 
in extending the market for salmon caught in these rivers. 
Mattole River.—This is a small and unimportant river in the south- 
ern part of Humboldt County, and is said to have a good run of 
salmon each year, but no commercial fishing has as yet been carried 
on here. 
Some salmon fishing is now (1915) carried on at Fort Bragg, in 
Mendocino County. The Noyo River debouches into the ocean at 
this place. Shipping salmon from here is now possible, owing to a 
branch railroad having been built to the coast at this point. It is 
probable that, as other points in the region between San Francisco 
and Humboldt Bays are made accessible by the railroad, the salmon 
fishery will be expanded very considerably. 
Sacramento and San Joaquin Rwers.—These two rivers are the 
most important in California. The Sacramento is quite crooked, 
the distance by river from Red Bluff to San Francisco being about 
375 miles, while the distance by rail between these two places is only 
225 miles. The river rises in several small lakes in the mountains 
about 20 miles west of Sisson, in Siskiyou County, and for nearly 
half its length flows through a narrow canyon. The upper portion 
is a typical mountain stream, with innumerable pools and rapids. A
