ing from, its practical value ; for every student is most certain to 

 remember, and most likely to practice, the things he really under- 

 stands. There are, of course, practical limits to explanations ; I 

 have had to use my own judgment as to where these limits are 

 reached. 



My work on this little book has covered more than two years. It 

 was at first proposed that a set of leaflets on Philippine agriculture 

 be written, and Mr. Edgar M. Ledyard was associated with me in their 

 preparation. Later, when it was decided that a book, rather than 

 a set of leaflets, was needed, a more homogeneous treatment became 

 necessary, and being absent from the Philippines, I completed it 

 alone, and am individually responsible. I wish to express here my 

 obligation to Mr. Ledyard for his help on the preliminary work, and 

 for helpful criticism of the completed manuscript. For helpful criti- 

 cism and suggestions, thanks are also due Dr. David P. Barrows, 

 Director of Education for the Philippine Islands ; C. W. Burkett, 

 joint author of Agriculture for Beginners; K. L. Hatch, joint author 

 of Elementary Agriculture; W. J. Spillman, United States Depart- 

 ment of Agriculture ; John W. Ritchie, author of the Physiology and 

 Hygiene used in the Philippines; E. N. Henderson, Adelphi College, 

 Brooklyn, N.Y. ; F. M. De Forest, St. Paul's School, Concord, N.H. ; 

 W. W. Rodwell, Division Superintendent, Laguna Province, P.I. ; and 

 H. H. Buck, Division Superintendent, Batangas Province, P.I. 



For the use of photographs, many of which are copyrighted, ac- 

 knowledgment is made to Hon. Dean C. Worcester, Secretary of the 

 Department of the Interior, Philippine Islands; the United States 

 Department of Agriculture, Washington, D.C. ; 'La Hacienda; The 

 World's Work; Dr. Harold W. Fairbanks ; Professor John W. Ritchie ; 

 and Caspar W. Hodgson. 



Finally, my greatest obligation is to the publishers, who have been 

 most generous of time, labor, and expense.
