application of his methods to plant and animal raising are of the 

 utmost importance in assisting the breeder to develop the qualities 

 he desires and breed for those qualities only. 



De Vries. Another name often mentioned with reference to 

 plant breeding is that of Hugo de Vries, the Dutchman who 

 has showed that in some 

 cases new kinds of plants 

 arise by sudden and great 

 variations known as mu- 

 tations. Professor Morgan 

 has actually produced new 

 species of fruit flies as a 

 result of his careful study 

 of mutants. De Vries's 

 work, with that of scores 

 of other workers in hered- 

 ity, is paving the way for 

 the practical plant and 

 animal breeders. 



Burbank. We must not 

 close without a mention of 

 Luther Burbank, whose 

 work with plant hybrids 

 has won him everlasting 

 recognition as a benefactor 

 of man. He was born in 

 Lancaster, Massachusetts, 

 on March 7, 1849, and he 

 died at his home in Santa Rosa, California, on April 11, 1926. As 

 a boy he was interested in the out-of-doors and particularly in 

 plant life. He was known as the Wizard of Santa Rosa because 

 there his experimental farm was located and there he developed 

 most of his new and improved plant forms. The Burbank potato, 

 witrr its large yield, would alone be a monument, but he followed 

 this with literally hundreds of improved and new forms. He pro- 

 duced a cross between a plum and an apricot, which he called a 

 plumcot. He crossed a small cream-colored berry with a large
