TABLE III. 



Shozviiig fJic Correlation hcizvccn Fertility and Hatching Quality 

 of Eggs. Records for Hatching Season of ipo8. Pullets and 

 Yearling Hens combined. 



Such correlation tables for the 1908 and 1909 records are 

 exhibited as Tables II to V inclusive. 



The data for 1909 are given in three tables, while those for 

 1908 are given in one. In the first of the 1909 tables (Table 

 III) both pullets and yearling hens are included. Table IV gives 

 the 1909 pullet records separately and Table V the 1909 year- 

 ling hen records separately. Owing to an oversight, one more 

 bird is included in the combined than in the separate tables. 

 This makes no difference in the results. 



Even from the most casual examination of these tables it is 

 apparent that there is a general tendency for birds showing a 

 relatively high percentage of infertile eggs (i. e., low percentage 

 of fertile eggs) to show a relatively low percentage of fertile 

 eggs hatched and vice versa. Thus, if one examines the first 

 three rows of Table II it will be seen that the majority of the
