PREFACE. 



The present inventory, No. 10 of our series, covers a number of 

 introductions almost equal to the entire number included in the pre- 

 vious nine inventories. It is put forth as the first part of the record 

 of the permanent work of this office with these introductions, and 

 shows what seeds and plants have been introduced. The completion 

 of the record requires a report of the disposition made of these seeds 

 and the results obtained from the experimental work done in this coun- 

 try. Such records will appear from time to time as our different intro- 

 ductions are tested and either discarded or found to be valuable addi- 

 tions to the plants cultivated by American farmers and gardeners. 



The introductory statement by Mr. Fairchild covers the general 

 information in regard to the sources from which these introductions 

 have been obtained, and I wish in addition to emphasize the fact that 

 the seeds and plants represented by this inventory have all been dis- 

 tributed, and that the inventory is in no sense intended as a check list 

 to enable persons to call for seeds and plants with which they would 

 like to experiment.
