PREFACE TO THE FOURTH REVISED 

 EDITION. 



The large use of Popular Fruit Growing in all sections of 

 the country and the ever-changing horticultural conditions have 

 made it seem best to revise some portions of the book before 

 this, the Fourth Edition, goes to press. Some rearrangement of 

 the subject matter has been made in order to conform more 

 closely to the usual plan of teaching fruit growing in American 

 schools and colleges. In a number of cases, additional material 

 has been incorporated where conditions have c"hanged or experi- 

 ence has shown that the subject was not discussed at sufficient 

 length in former editions. 



It is but fitting at this time to add to this preface a short

 thought or said. 



Ten years following graduation were spent in practical 

 nursery and farm v.'ork, gradually gaining the experience that 

 would be of value to him in later life. In 1888 he came to Min- 

 nesota as Horticulturist of the Experiment Station and Professor 

 of Horticulture in the University, which positions lie held till 

 his death. There were very few students and practically no 

 equipment in the Department of Horticulture at the time of Pro- 

 fessor Green's coming. He not only built up a strong Horticul- 

 tural Division and very greatly advanced the horticultural inter- 

 ests of the state, but also helped to establish tlie School and Col- 

 lege of Agriculture on the solid foundation on which they exist 

 in Minnesota today. He also found time to serve the state in
