Diagram oj Tree Grafts 



This is a leaf from Mr. Burbank's plan book. It is 

 a sort oJ shorthand or diagramaticat record that condenses a 

 large amount oJ injormation into small space, leaving room Jor addi- 

 tional records should they be called Jor. Such a page 

 seems cryptic to the casual observer, but to 

 Mr. Bur bank himself it is 

 Jull of meaning.
