ACKNOWLEDGEMENTS 



In planning and preparing the work, we have had the 

 benefit of counsel from a number of teachers, practical 

 farmers, and others who are regularly engaged in the 

 professional study of agricultural problems. The text 

 has been greatly improved by the careful reading, either 

 in whole or in part, by the following persons: Miss 

 Dora Schnell, formerly of the Dallas public schools, 

 who has very kindly prepared the questions at the end 

 of the chapters; Miss Ada Henderson, of the public 

 schools of Cameron, Texas; Mr. and Mrs. T. P. Robinson, 

 both of them experienced teachers, who are also success- 

 ful farmers. The above may be taken as representing 

 the teaching and popular point of view. 



On the professional and technical side, valuable 

 assistance and criticism have been given by Prof. J. H. 

 Connell, President of the Oklahoma A. and M. College; 

 Prof. F. R. Marshall, late Professor of Animal Husbandry, 

 Texas A. and M. College, but now of the University of 

 Ohio; Prof. T. V. Munson, our most accomplished and 

 distinguished horticulturist; Prof. W. H. Long, Professor 

 of Biology in the North Texas Normal College; Prof. 

 C. O. Moser, Special Agent, United States Department 

 of Agriculture, and supervisor of the Denison Demon-
