f LINE BREEDING I 



The best illustration and explanation of what Line Breeding is 

 that has come to my notice is the chart prepared by I. K. Felch, a, 

 very capable poultryman of Natick, Mass. Mr. Felch is now a veteran 

 poultry breeder eighty years of age, and has been an acknowledged au- 

 thority for over half a century, a judge, fancier, writer and leader in the 

 poultry arena, and looked up to by his co-workers in the field for better 

 Standard poultry. My request for permission to use his chart in this 

 book brought forth a cordial and friendly letter from him, together with a 

 copy of the chart, a printed explanation, and an electrotype of the line 

 drawing. I had a new drawing prepared and a new plate made, and the 

 explanation is reproduced ad-literatim. I believe this chapter will be ap- 

 preciated by readers of this book. 



"Each dotted line represents the female as having been selected from 

 the upper group, while the solid line shows the male as having been taken 

 from the indicated upper group. Each circle represents the progeny. 



To wit: female No. 1 mated 

 with male No. 2 having pro- 

 duced group No. 3 which is i 

 the blood of sire and dam. 



Females from group No. 

 3 mated back to his own sire. 

 No. 2, having produced group 

 No. 5, which is f of the blood 

 of the sire, No. 2, and | the 

 blood of the dam. No. 1. 



A male from group No. 3, 

 mated back to his own dam, 

 No. 1, produces group No. 4, 

 which is f of the blood of the 

 dam No. 1, and i the blood of 

 the sire No. 2. 



Again we select a cockerel 

 from group No. 5 and a pullet 

 from group 4, or vice versa, 

 which will produce group 7, 

 which is mathematically half
