The Evidence— 



THE Burbank books were hardly off the press and in the 

 hands of the first readers before evidence began to 

 come in proving beyond question that the great plant 

 breeder's contribution to plant lovers is just as fascinating 

 and helpful to them as the publishers had confidently pre- 

 dicted. 



An early^ and one of the finest testimonials^ was volun- 

 tarily submitted by Prof. M. V. O'Shea^ Professor of Edu- 

 cation at the University of Wisconsin. Professor O'Shea 

 was not only frankly enthusiastic in his praise of the works 

 of Luther Burbank^ but was willing that we should include 

 his letter in this booklet as an assurance of their value to 

 prospective owners of the books. Read his letter on the 

 opposite page. 



Another interesting and valuable indorsement came from 

 quite a different source — from an amateur gardener^ who 

 wrote in part: "These books will certainly be a great bene- 

 fit to plant improvement, if the people interested in this 

 work will only read them. A man in this business could 

 not make a better investment than to buy a set and read it 

 thoroughly. The methods are explained so clearly and 

 with the help of the many and beautiful illustrations_, there 

 is no trouble at all to understand the many subjects de- 

 scribed. It is a great work for which the world should 

 feel grateful. I am only an amateur with a small garden, 

 but I am very much interested in this work and I am sure 

 I will learn much from the books." 



Such letters as Professor O'Shea's and the amateur 

 gardener's^ are most encouraging to the publishers in their 

 efforts to assist Mr. Burbank in preaching the gospel of 

 the soil to plant lovers everywhere.
