and destructive Sierra Nevada, to reach final 
destination in California and the region northward. 
2.—DISTRIBUTED BY WARM JAPAN 
CURRENT. 
A very important agency helping on the capture 
and directing the distribution of the trees all along 
the western coast from California to Alaska, is the 
presence in the north Pacific Ocean of the warm 
Kuro-Siwa , or Japan current, primarily a hot trop¬ 
ical current striking the islands along the southern 
coast of China and deflected northward to be more 
deflected by tbe Japan islands and hurled north¬ 
eastward across the Pacific Ocean, there striking 
the southern side of the long chain of Aleutian 
Islands, which turn a part of the current down 
along the coast of America, delayed and accumu¬ 
lated during its long sweep by the many islands 
and capes on the way, while its heat rises into the 
atmosphere, carrying with it enormous quantities 
of water. 
3 .—NOURISHED BY MOIST EANDWARD 
breezes. 
Another factor closely connected with the pre¬ 
ceding is found in the cool, broad, overruning Pa¬ 
cific breezes that prevail most of the year 011 the 
northwest coast. Mingling with the heated and 
moisture-filled air over the Japan current, the vol¬ 
ume presses inland, the moisture condensing and 
falling most copiously upon the nearest cool ele¬ 
vations—giving sustenance and stimulus to the 
richest and most remarkable forest on the face of 
the globe.
