AVERAGE TEMPERATURES FOR THE MONTH OF JULY 



AUGUST 



Sky: For August we have fairly complete records for only 2 

 years, 1900 and 1906. We have pretty full temperature records 

 for 1902 but few. records of other weather conditions. 



Our records show an abundance of cloudy weather, and for the 

 summer of 1906, a considerable excess. In many cases of cloudy 

 weather, however, the clouds were much broken up, permitting 

 many bright days and clear bits of sunshine. 



Winds: August is notably a month of calms and it is due to 

 the placid untroubled surface of the lake that the plankton scum, 

 which begins either at the end of the preceding month or the be- 

 ginning of this, forms on the surface and reaches its maximum de- 

 velopment. West winds are the least frequent; east winds the 

 most so. 



Storms: In keeping with the prevailing calm, storms are rela- 

 tively infrequent. 



The following is the record in tabular form :
