1 The hive was not on scales for the first few days of observation. On some later days an accumulation 
of moisture on the tops and on the bottom-board introduced erroneous records of weight, and such days 
have been omitted from this tabic. 
2 Figures in this column indicate the minimum limit of the average loads for the day and not the actual 
average load. Since consumption of stores and evaporation continue throughout the day, the actual 
average load can not be obtained from weights of the entire hive. This limit can only be determined for 
those days when the hive showed a gain due to incoming nectar.
