FOREWORD TO VOLUME V 



Unquestionably the greatest work which Mr. 

 Burbank has done in the line of tree fruits has 

 been with plums and that greatest plum of all, the 

 prune. It has been his purpose in this volume, 

 however, to limit in no wise its value to the plum 

 and prune grower; but, because of the number and 

 completeness of the experiments outlined, it is 

 designed to have a broad, practical worth to the 

 producer of other desirable new fruits, or in fact 

 of any other plants. 



The reader, by this time, must well realize that 

 Mr. Burbank's methods, all of them, are plant 

 methods rather than flower methods, tree methods 

 or vegetable methods. 



This book concludes with one of Mr. Burbank's 

 most interesting achievements the production of 

 the plumcot, a combination between trees of 

 different species, such as men of science had 

 always thought to be impossible.
