THE PROBLEMS IN MATING AND IN EGG PRODUCTION 99 



1 45 eggs per hen per year. For comparison and tabulation with 

 these carefully kept and accurate records the percentages of 

 general egg production as indicated by the receipts at New 

 York are taken— setting the figures back one month to allow 

 for the time required to get the eggs to market. 



To show the annual variations as they occur on a large 

 scale the following table is given. The figures for the months 

 are the percentages of the receipts for the year which arrived 

 in each month. 



In the average percentages fractions are adjusted to give 

 the percentages in the whole numbers that will express the 

 situation most satisfactorily. Thus a number of small frac- 

 tions omitted in figures for the reason of heavy production 

 are added to the figure for one or more months of fight pro- 

 duction where the error is of less effect when the percentages 

 are applied to show the actual egg production month by month. 



In the next table the Beltsville and Storrs distributions are 

 given first, then the averages from the first table — ^adjusting
