siderably greater than in L935 or 1936. The streams were lower for a part of the 

 summer of 1936 than in 1935, and this is reflected in slightly higher silica values in 

 that year. 



Karluk Lake receives silica, in part from the action of the water on the silica bearing 

 rocks on the bottom and on the beaches, and in part from its tributary streams which 

 leach the silica from their respective watersheds. Consequently, the yearly increment 

 of silica, although undoubtedly affected by temperature and precipitation, is probably
