VI PREFACE. 



reliable. At the same time, the book has been thor- 

 oughly renovated in all departments, and it has been 

 much extended to meet the needs of the many inquir- 

 ies which are born of the recent teaching and experi- 

 menting in rural affairs. A chapter has been added 

 upon greenhouse work and heating, and another upon 

 the current literature of American horticulture. In its 

 completed form, therefore, it is hoped that the volume 

 will serve to codify and epitomize the best part of the 

 scattered and disconnected horticultural advice and 

 practices of the time.

PREFACE TO THE FOURTH EDITION. 



ALTHOUGH the third edition was given to the public 

 only last May, a fourth edition is now called for by 

 the publishers. I have made various corrections and 

 explanations in the text, and have added paragraphs 

 upon yields of leading seed-crops, the customs regula- 

 tions, methods of preserving posts in vineyards and 

 other places, some figures of grape packing, a state- 

 ment of the pollination of grapes, and a scheme for 

 the classification of horticultural industries; and the 

 index has been extended until it now comprises about 

 two thousand entries.
