LUTHER BURBANK 



a single genus or order, I have extended my 

 observations to almost every form of plant, testing 

 species by thousands, and individual specimens 

 by hundreds of thousands or millions, in my 

 experimental gardens; and only by exception has 

 complete record been kept of all details of any

Yet I have had the good fortune to produce, I

 I stopped to make meticulous record of each 

 experiment, I doubt if I should now know more 

 than I do about even my less important products, 

 and I surely should have been able to produce 

 only a fraction of those that I have produced. 

 Methods and Results 



Yet it must not be supposed that I have alto- 

 gether refrained from graphic recording of the 

 progress of my tests. The fact is quite otherwise. 

 I have kept in the aggregate a vast body of records, 

 and have had them always at hand, under my eye 

 from day to day, telling of the essentials of my 

 hybridizing and other experiments. 



My "plan books" have been a constant aid to 

 memory, and guide to further effort. 



My record books have set down in black and
