the trees might die dov/n entirely. The young 
growth of calleryana is quite susceptible to 
■blight; in greenhouse experiments he has had 
it that from ? to 3 feet of branch died back 
below the point of inoculation. (This oc- 
curred with the type from Oroville, ealif.) 
He also advises us to grow this No. 2446a 
by ourselves for some time until its value as 
regards resistancy to blight can be determined. 
Should it be distributed it shouldjbe done so 
with reserve concerning its value. --I trust 
you'll inform Mr. Bisset about this matter. 
One question I would like to have ansv/ered, 
if possible. How many stocks for pears are used 
annually in the United States by nurserymen? 
Are statistics available? How many ulants of 
E.' calleryana v;ould be wanted annually for the 
mild-v/intered regions of the United States? How 
many P. ussuriensis would be desired evei'y year 
for the colder pear -growing sections of the 
United States? 
• I am giving Prof. Reimer unreservedly all 
of the information on pears and connecting 
problems that I have collected in all of these 
years and around here I have taken him to special 
trees ViThich often has taken me a few weeks to 
spot. He is taking many fotos and I suppose his 
observations may appear quicker into print than 
mine; ^t is a somewhat painful task to give away 
all of one's information, but then — pioneer work, 
like I am doing, is a missionary work, one is the 
sov/er and others are the reapers! — It is all 
for a good purpose and the benefits fall to all 
humanity. 
Our intentions v/ere to have left several 
days ago for Ichang, but it has been raining 
again for many days and nights and not only 
that all our baggage would get ruined but the 
condition of the trail beggars description. We 
hope that the revolution, which rages in Szechuan 
and Hunan, is not carried into Hupeh, but, — 
things do not look bright here in China. 
P. S. Please discuss some of the questions 
mentioned with Mr. Waite and Dr. Galloway, should 
you have the time. Mr. Dorsett may knov/ whether 
we have the land available at Ghico for all of 
this pear seed.
