IV PREFACE, 



works, have been gathered in this Handbook and arranged 

 in such a manner as to make them easily accessible and con- 

 venient for reference purposes. 



The present volume is founded on the Dairy and Agricul- 

 tural Calendars previously published by the author. Much 

 new material, both original and compiled, has, however, been 

 included, and special articles, tables, statistics, etc., have been 

 verified and brought up to date, making the book, as it is hoped, 

 of considerable value, and securing for it as favorable a reception 

 as was accorded its predecessors. 



The author takes this opportunity of thanking the follow- 

 ing specialists who have so materially increased the useful- 

 ness of the book by comprehensive, concise contributions on 

 subjects in their particular lines of study: Professors W. H. 

 Caldwell, J. A. Craig, John W. Decker, L. H. Dewey, F. H. 

 Farrington, B. E. Fernow, E. S. Goflf, A. W. Richter, H. L. 

 Russell, Thos. Shaw, Wm. P. Wheeler; and Messrs. John 

 Boyd, W. G. Clark, M.D.C., N. S. Fish, J. D. Frederiksen, 

 H. B. Curler, S. Hoxie, J. Noer, M.D., J. H. Pickrell, H. B. 

 Richards, L. P. Sisson, J. McLain Smith, and C. M. Winslow.
