province, quite near Shanghai, 
Mr. Meyer is the logical man to send, since he knows 
how to travel in China, has already familiarized himself 
with the plants of northern and central China, and is a 
tried explorer capable not only of finding new things, 
but of sending them in and landing them here alive. 
It is desirable that Mr. Meyer should get from the 
region around Peking, before he goes south, larger quan- 
tities of certain of his previous introductions: 
The davidiana peach (Am ypdalue dayidiana ) has shown 
so much promise as a stock that a considerable demand 
for the seeds of this species has arisen, which the few 
fruiting trees now in California are not capable of 
supplying. Quantities of seed of this species are de- 
sired and these cannot be secured through correspondence. 
The Chinese chestnut ( Castanea mollissima ) has shown 
itself hardy and semi-resistant to the bark disease, and 
it seems desirable to distribute to experimenters more 
trees than we have so far bTeen able to secure seed for. 
It seems desirable even to test out small acre plantings 
of this Chinese species. 
The Chinese pistache ( Pistacia chinen s is ) has proved 
such a heat, drouth and alkali resistant shade tree that 
we could to advantage use large quantities of seed of it 
for propagation. It grows to an immense size and is one 
July 25, 1916.
