In a letter received from Mr. I. M. Karzin, Issyl-kul, Ak- 

 molinsk Government, Siberia, dated March 2, 1916; 



"Many thanks or the seeds sent of American plums, 

 which Prunus americana nigra proves fully 

 Siberian climate. This plum, sent in fall 

 splendid growth and endured very well the severe winter 

 1914-1915, with frost down to -40 degrees R."

NOTES ON BEHAVIOR OF PREVIOUS INTRODUCTIONS. 



Amygdalus davicliana. Mr. Marsden Manson, San Francis- 

 co, Calif., in a letter dated May 20, 1916, says: "Amygdalus 

 davidiana is by far the best and hardiest stock I have ever 

 known and its introduction has repaid the support of the 

 Bureau of Plant Industry for several years. Peaches and 

 nectarines on A. davidiana are growing and bearing well for 

 young trees." 



Amygdalus persica. 33219. Vainqueur Peach. Fruits of 

 this variety were sent in to this office on June 5th, and 

 referred .to the office of Pomological Investigations. Mr. 

 Wight of 'that office, reports as follows: "This peach com- 

 pares very favorably in quality with other early varieties, 

 such as Alexander, Amsden andSneed; and since it is earlier 

 than the Alexander, it may have considerable value as an 

 early peach, at least for local markets; and I think it 

 also has considerable value as breeding material for pro- 

 duction of an early peach of still better quality. The 

 flesh next the stone has a slightly bitter taste, but this 

 might not have been prominent if the specimens could have 

 been well ripened on the tree, as they were picked rather 

 green in order to send them successfuly so far in a mail- 

 ing box." Mr. R. L. Beagles, in charge of the Plant In- 

 troduction Station at Chico, Calif., reports that this 

 variety ripened its fruits about ten days earlier than the 

 Alexander, the most widely grown, early, commercial peach 

 of the Pacific States, and is therefore likely to prove a 

 very valuable peach. 



Ilex cornuta. 22979. Holly. From F. N. Meyer, of Soo- 

 chow, Kiangsu, China. Mr. Meyer sent in the following note 

 with this form: "A very ornamental bush or small tree, 

 loaded in winter with scarlet berries. A slow grower and 

 probably not hardy North. Chinese name Ta hit tse." At the 

 Plant Introduction Garden, at Chico, this form has succeed- 

 ed admirably and promises to be one of the best hollies 

 for regions where the winter is not too severe. Probably 

 it would do well from Washington south. 



Juniper-US chinensis. 18577. Chinese Juniper, a colum- 

 nar form. From F. N. Meyer, Shan-hai-kwan, China. Trees
