used. Normally rainy days are here considered (arbitrarily) as those 

 with normal daily means (Bigelow's table, Bull. R) of over 0.10 inch.

 These data are given in column 2 of table 13. 



Table 13. — Number of days in the -period of the average frostless season with normal precipita- 

 tion of more than 0.10 inch and xvith normal precipitation of 0.10 inch or less, the latter 

 also expressed as percentage of the number of days in the average frostless season. (Plates 

 47, 48, and 49.)
