body. Infection has not "knocked" this sub-structure from 
under any of the now resistant varieties, not even the 
most susceptible ones. 
16. All the promising species and varieties have been 
worked on dwarf stock to induce early fruiting, so as tp 
get seed of the species and wood of the varieties. Many 
tender varieties have been worked on resistant species and 
varieties and then liberally infected to see if continuous 
blighting of the tops will affect the stocks. Results so 
far are negative. 
17. There is urgently and immediately needed as much 
as 100 pounds of the seed of the true P. ussuriensi_s. from 
country about three days' march north of Peking, China, and 
in addition what seed that can be obtained, up to 100 pounds, 
of P. calleryana . from near Ichang, China. Meyer said the 
last named place may be reached in about three or four days 
from Peking. One takes the train at Peking and does south 
to Hankau; thence, by boat to Ichang. Reimer is extremely 
anxious that both lots be obtained and in his hands not 
later than February 1st next. The tree at Oroville, Gal., 
is of the southern type of calleryana. It comes from some- 
where near Kong Kong. Reimer does not place much value in 
this stock, except for' southern California, and possibly 
for breeding purposes. 
18. The seed of the two types indicated is to furnish 
December 31, 1916.
