northern boundary of Lake County. The latter peaks are by checked aneroid 

 slightly higher than Snow Mountain. The signs of glaciation included well 

 preserved striae on bedrock, small cirques, and moraines. The glaciated areas 

 were small, the greatest length of any single glacier so far as found being not 

 over 2 miles.

VARIATIONS IN RAINFALL IN CALIFORNIA 

 BY WILLIAM G. REED 



(Abstract) 



Wet and dry years have been recognized in California. An examination of 

 the available records for the past 25 years shows that a wet or a dry period 

 is not alw^ays State wide. The State may be divided on the basis of the char- 

 acter of the curves of seasonal precipitation and the time and duration of wet 

 and dry periods into three sections. A northern, a central, and a southern 

 type of rainfall variation have been made out from the preliminary study, 

 although there is considerable irregularity at individual stations. The pre- 

 liminary examination shows the necessity of a careful study of all the records 

 in order that the limits of rainfall variation and the areas which are subject 

 to similar variation may be determined.
