ACKNOWLEDGMENTS 



The present study would have been impossible but for the 

 hearty cooperation of a large number of persons, as state super- 

 intendents, high-school inspectors, officers of administration or 

 instruction in the state universities and agricultural colleges, and 

 officers and teachers in the different schools studied. For the 

 mass of detailed information used in Chapters II, III, IV, part 

 of V, and VII, I am particularly indebted to the superintendents, 

 principals, and teachers in the schools listed. (See footnote, i.) 

 The compilation of the list itself was rather difficult in the 

 early stages, since agricultural instruction was so new in 1907 

 and because few states had at that time undertaken to collect 

 information regarding the work. 



Especially am I indebted to Mr. D. J. Crosby, Specialist in 

 Agricultural Education of the United States Department of Agri- 

 culture, for the free use of the materials and facilities at the 

 command of the office of Experiment Stations. 



Much appreciated assistance in reading the manuscript and 

 in checking up the tabulations has been rendered both by Mr, 

 Crosby and by Mr. F. W. Howe, then Assistant in Agricultural 

 Education in the Office of Experiment Stations, and now Su- 

 pervisor of Agricultural Education for the New York State 

 Education Department. 



The present investigation has been carried on under the 

 auspices of the department of secondary education. Teachers 

 College, Columbia University. I owe a great debt to Pro- 

 fessor Julius Sachs, head of the department, and to Dr. David 

 S. Snedden, now commissioner of education for Massachusetts, 

 for their helpful direction and kind suggestions at all stages of 

 the work.
