It is very pleasing to hear that Ulrnus pumila 
increases in popularity and that Pistacia chinensis 
turns out to be such a desirable tree, notwith- 
standing a few cases of skin irritation caused by 
it in Georgia. Maybe I can get hold of one thous- 
and lbs. of seed this fall. 
Tli^* SuGOiomia ulmoides is hardy even in central 
Kansas comes as a genuine surprise to me. I'll see 
whether I can get more seeds this fall. Could you 
perhaps tell me who this travelling friend of Mr. 
J. W. Riggs» is, who has seen this hardy caoutchouc 
tree in its native habitat? Could it be Mr. S. H. 
Wilson. If not, could not this gentleman send you 
a few lbs. of seeds? Please ask Mr. Riggs about 
this traveller who must be a man who has been much 
about in China, for Eucommia is far from common 
here. 
Getting better stocks for plums and cherries; 
yes, that is some problem! For what sections of 
the United States do you want them? There are 
many forms of Prunus and Cerasus in Western China, 
also in Manchuria and Japan; to get seeds, however, 
in quantity, that is the great question. It is not 
always easy to find a thing like the davidiana 
peach, which happens to be fairly common in and 
around Peking. Have you tried Prunus mume or P. 
triloba as stocks for plums and P. lannesiana for 
cherries? These three might be gotten in quan- 
tities from Japan, when special requests are made 
for them. We surely ought to try to have collect- 
ions of various species of Prunus, Amygdalus, and 
Cerasus at our stations, so that we could experiment 
in a small way on these stock problems. 
If anything comes up in the matter of needing 
material from China, please make the habit of 
dropping such notes into a special envelope on 
your desk and you may send them up to me once or 
twice a year. 
On February 9, I917, Mr. Meyer answered Mr. Stuntz' letter of 
lovember 11, I916, (see p. 2? of the 1916 project report) re- 
garding the Zizania latifolia desired by Mr. Chambliss. The 
four plants which Mr. Meyer sent in under his No. l?6l reached 
us on January 3. 1917. They were given SPI No. 440 69 and 
were ordered grown in quarantine. The plants were delivered 
December 31, 1917.
