Perhaps the most important fact, from the present point of 
view, exhibited by this table is that pertaining to winds. It will 
be noted, for San Diego, that the maximum velocity for the year 
was 36 miles an hour, in February. On the basis of the “*‘ Beaufort 
9? 
Seale’’ of wind velocities, this is a ‘‘Strong Breeze.’’ February 
and March are the climax of the stormy season. For the months 
May to December, inclusive, the maximum velocities run from 
‘*Centle Breeze’’ to ‘‘ Fresh Breeze.’’ 
La Jolla, the suburb of San Diego at which the laboratory is 
located, is on a rocky point jutting into the open sea with water 
of 200 fathoms attainable inside of five miles; so the ecological 
problems of oceanic plankton, and of bottom-forms can be here 
attacked under peculiarly favorably conditions. 
The western boundary of the area corresponds roughly to 
the edge of the continental shelf in this region, and immediately 
beyond this 2,000 to 2,300 fathoms are reached. While this 
extreme depth is distant about 200 miles from San Diego, by 
making San Nicholas Island a temporary base the 2,000 fathom
