WINDS. 
All the heavier, more vigorous kelp beds along the mainland and 
island coasts of southern California lie fully exposed to the wind. 
One may safely say that the more exposed the kelp is to the wind, 
the more vigorous are the plants. The strong winds and rough seas 
of San Nicholas and other outlying islands have given rise to kelp 
with heavy stipes and thick, tough, leathery leaves of a deep chest- 
nut brown color. On the other hand, the kelp growing in the quiet 
waters of the island coves has slender stipes and broad, thin leaves
