are two valuable trees which are well worthy of dissemination, 
and seed of these can only be secured by a collector on the 
spot. 
The success of the Chinese cabbage or pai tsai, which 
has reached the commercial stage in many parts of the 
country, and the knowledge that there are nxanerous strains 
in Korth China which differ in their habit and season of 
maturing from those we have, make it desirable that a 
special collection of seed of these Chinese cabbages be 
made. 
These commissions will require Mr. Meyer to go to 
North China and spend two or three months there before 
proceeding south. 
The main exploration work will be in the southeastern 
provinces of China, and because of the large nximber of new 
plant species which exist there, it has been suggested by 
Mr. Swingle that Mr. Meyer should put himself in touch 
with the large herbarium and other facilities which Mr, 
Merrill has created in Manila by a brief visit to the 
Philippines before he actually pushes into the interior. 
He can by this means make arrangements to have his her- 
barium specimens determined by Mr. Merrill and duplicates 
placed in safety in the collection there in Manila, while 
the originals are on the way to Washington. He may find 
it to advantage, further, to send certain duplicate scion 
and seed shipments to Manila for propagation.
