CLOUD AND PRECIPITATION. 



Tlie great excess of bad weather during 1912 over 1911 is clearly indicated. From March 

 to October 1911 there wore 2-5 hours out of every hundred with snow or drift ; in the same 

 months of 1912 the percentage was 41. Collecting the results according to seasons we have the 



following : 



Table 89. 



Number of times Snow and Drift were recorded in 100 hours 



The summer has the least frequency of snow and drift, while the other seasons have 

 practically the same. For the summer we have only observations for one year, but the ex- 

 pedition was at Cape Evans for another, and there is little doubt that the relative freedom 

 from bad weather found during November, 1911, to January, 1912, was repeated during these 

 months in other vears.
