PREFACE. 



As a result of his observations on the agriculture of Japan, Mr. 

 D. G. Fairchild has contributed several papers designed to interest 

 American cultivators in new crops. Three of these papers are pub- 

 lished in this Bulletin. One on a Japanese paper plant calls the atten- 

 tion of farmers in the mild and humid regions of the United States to 

 a possible new industry, while those on the udo and on the Japanese 

 horse-radish will doubtless prove of interest both to market gardeners 

 and amateurs who take pleasure in cultivating the best vegetables. 



The plants and seeds received from Mr. Lathrop, through Mr. Fair- 

 child, have been placed for trial with reliable horticulturists, and the 

 results of these tests will enable us in the course of time to report 

 more fully regarding the adaptability of these plants to our conditions.
