There was, however, a gradual and constant lessening of the daily 

 consumption of honey, as is apparent in Table I, which presents the 

 monthly and average daily figures. From this table it will be seen 

 that while in November the average daily consumption was 53.2 

 grams, in February the average was but 30 grams a day. For the 

 entire whiter 43.5 grams of honey were consumed, on the average, 

 daily.

Although the foregoing figures represent the usual daily conditions, 

 they do not by any means represent the actual daily consumption. 

 As will be seen in Table II, there was no such degree of constancy as 

 is represented by these averages. Taking the 10 days at the middle 

 of each month, it is possible to represent prevailing conditions for 

 that month. Thus the data of Table II are a fair representation of 

 the actual variations as they occurred during the winter. It will be 

 seen in this table that the daily variation in weight is all the way from 

 a loss of 130 grams in some cases to no loss whatever or even an in- 

 crease of 40 grams. Therefore it is hardly possible to assume that the 

 weights of the entire hive will throw any light on the amount of 

 honey consumed in a single day. 



This increase in the weight of the hive during bad weather is a 

 fact which, so far as the author is able to learn, has not heretofore
