He wrote further on February 12, 1917. froxa Peking, trans- 
mitting his Eos. lAOh to 142b. Nine ounces of seed of each 
of these were received on March 20, 1917. given SPI Nos. 
44316 to 44318, and turned over to Dr. Viehoever, of the 
Bureau of Chemistry, on March ?9, 1917. together with a 
copy of the following extract from Mr. Meyer's letter of 
February 12, 1917: 
According to your letter of January 4, 
1917, many species of Brassica seeds are being 
exported from China, but I fail to see any B. 
iuncea being mentioned and yet this seems to 
be the species that is being cultivated here 
up north. 
My interpreter went around for a few days 
and says that this is the only kind of seed 
from which mustard is made here in China. The 
various dealers deny that other seeds are mixed 
with it. I suppose if adulteration takes place 
it must be in the Yangtze river ports, where 
Brassica campestris is raised so extensively 
as a winter crop on low lands, \7hen once 
further south we will investigate further. 
As regards the possibility of obtaining 50 
kilos of various Brassica seeds, well, I think 
that can be done; the price for 50 kilos of B. 
.iuncea here in Peking will be c.a. $24.00 to 
$28.00 Yuan silver. 
Concerning the exportation of mustard seed 
from up here, it is said that very little leaves 
this section of the country. If I can lay my 
hands on lists of the custom house, I»ll look 
this matter up. 
I trust these three samples may be of some 
use to the Bureau of Chemistry. 
Mr. Pairchild requested Mr. Meyer, in a letter dated March 27. 
1917, to secure the fifty kilos of mustard seed referred to.
