lake whose shore line is never subjected to ice 

 disturbance and a low beach flora which does 

 not have to bear the incessant impact of surf or 

 strong winds, for so effectively hemmed in is the 

 lake by the high and heavily timbered slopes 

 that strong and lasting wind currents of prevail- 

 ins: direction do not obtain. Furthermore the 

 expanse of water is not great enough to allow 

 the shifting air currents that reach the lake to 

 develop any surf action on this or that shore. 

 The lake is fed by one fair sized stream and by 

 a number of brooklets from the surrounding 

 hills. The per cent of organic matter in its 

 waters is necessarily comparatively large. 



With regard to the topography and structure 

 of the beach onlv a few words will be set down. 

 For some distance along one end of the lake, 

 the slope drops off rather suddenly in rocky 

 ledges and here the beach is only a few meters 

 wide. In front of gullies or ravines, the filling 

 in has been greater and a wider beach is the 

 result. On the side where the main stream that 

 feeds the lake flows in, a considerable stream 

 delta has been formed. The leach here is large-
