results of actual work for the past fifty 

 years among millions of living plants, 

 including almost every one known to 

 growers and many thousand species 

 never seen in cultivation, which have 

 been discovered by hundreds of my col- 

 lectors of seeds of wild plants from 

 every part of the earth, most of whom 

 (strangers to me) have sent these seeds 

 in gratitude for the work accomplished 

 here, or in exchange for seeds of my 

 improved plants for the various climates 

 from which the wild seeds came. 



All these thousands of varieties are 

 grown and most carefully inspected and 

 selections made for any promise they 

 may give of use for fruit or other food, 

 for flowers, foliage, lumber, fiber, ex- 

 tracts, perfumes or other chemicals, and 

 for combination with our well-known 

 cultivated trees, plants, and flowers, for 

 their improvement.
