6 PREFACE. 



ing this book for the press has been done by 

 my younger son, Ethelbert D. Warfield of Mi- 

 ami University. Great credit is also due to my 

 elder son, Prof. Benjamin B. Warfield, D. D., 

 now of Princeton, N. J., whose energy and 

 vigor of thought and pen gave me such essen- 

 tial aid in the earlier years of my connection 

 with the press; nor has the pursuit of the more 

 weighty things of theology destroyed his capac- 

 ity for taking an occasional part in the active 

 discussion of cattle matters. The papers which 

 have appeared over my signature have thus to 

 quite a large degree been of family origin; and, 

 as the time must come when I shall pass on 

 both the work of writing and breeding to them, 

 I am glad of an opportunity to make this ac- 

 knowledgment of their filial aid.
