 certain that on the first day the air was

 day the water was cold, owing to melted 

 snow, but the air was warm." 



This relation between the temperature 

 of the water and that of the atmosphere is 

 in all probability the determining factor 

 far more than the absolute temperature 

 of the water without reference to other 

 conditions. This is suggested at any rate
