52 MAINE AGRICUI^TURAI, EXPERIMENT STATION. I909. 



the egg production and other characteristics of the mothers 

 which produced the 250 so-called "registered" pullets. Then 

 the egg production of each mother's progeny may be compared 

 with her own production. The significant data on this matter 

 are shown in Table I. This table gives in the first column the 

 band number of each "registered" mother hen known to have 

 one or more daughters among the 250 pullets. The second 

 column of the table shows the number of eggs produced by each 

 of these mother hens between November i of her pullet year 

 and November i of the following year. The third, fourth and 

 fifth columns of the table show the number of daughters which 

 each of these mother hens had among the 250 birds. The first 

 of these columns gives the total number of daughters for 

 each mother. The second column (rubric "Nov. -Mar.") gives 

 the number of daughters of each mother which survived to 

 March i, 1908. The third column gives the number of daugh- 

 ters surviving until June i, 1908. , 



The sixth column of the table shows the number of eggs laid 

 by each of the registered mother hens in the experiment between 

 November i and March i of her pullet year. In other words, 

 this column gives the individual mother's winter egg record. 

 The seventh column gives the corresponding figures for the 

 daughters. In this column there is set down the average egg 

 production between November i and March i of the pullet 

 year of the daughters of each individual mother. For example, 

 it appears from the first line of the table that the 12 daughters 

 of mother hen No. 7 averaged to lay between November i and 

 March i, 14.83 eggs each, while in the corresponding period of 

 her own life hen No. 7 laid 33 eggs. The eighth column of the 

 table gives the egg record of each mother hen between March 

 I and June i. of the pullet year. Finally, the last column of 

 the table gives the corresponding figures for the daughters. In 

 this column are the averages between March i and June i of 

 each group of daughters coming from a particular mother.
