In a letter received from Mr. I. M. Karzin, Issyl-kul, Ak- 
molinsk Government, Siberia, dated March 22, 1916; 
"Many thanks or the seeds sent of American plums, of 
which Prunus americana nigra proves fully resistant to the 
Siberian climate. This plum, sent in fall of 1913, gave 
splendid growth and endured very well the severe winter of 
1914-1915, with frost down to -40 degrees R." 
NOTES ON BEHAVIOR OF PREVIOUS INTRODUCTIONS. " 
Amygdalus davidiana. Mr. Marsden Manson, San Franc i 6- 
go, 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 hu 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. 
Juniperus chinensis. 18577. Chinese Juniper, - a colum- 
nar form. From F. N. Meyer, Shan-hai-kwan, China. Trees
