Tritiewn aestivum (Poaceae), 54909. Common wheat. From 
Nanking, China. Seeds presented by Mr. J. Losslng Buck, 
acting dean, College of Agriculture and Forestry , Uni- 
versity of Nanking. "One of our students from Shantung 
told us that because of floods in the autumn a large 
amount of wheat was planted in the spring. This is the 
first time I have heard of spring wheat in China. These 
seeds are from Tung Tsao , Koo-yung District, Shantung."

Notes from Agricultural Explorers in the Field. 
Mr. J. F. Rock writes from KengHung (Chleng Rung) , 
Yunnan, February 18, 1922: 
"After one month and seventeen days' travel by 
caravan, I arrived at Keng Hung. The region I tra- 
versed took me over high mountain ranges and for days I 
traveled through chestnut and oak forests. I am unable 
to tell if they are real Castanea or Castanopsis; some

from Kengtung led over high hills to small alluvial plains 
which may have been lakes once upon a time, and which 
are now under rice cultivation. We usually stopped 
over night in the plains , sleeping in Buddhist temples, 
which is much safer than sleeping in the open. The 
whole village crowded into the temple to watch us 
eat, and some said they wanted us to go to bed to see 
howwedid it. My gas lamp (pressure lamp) was of great 
interest. Never in all their lives had they seen such 
light, and what proved of greater interest was the 
electric flash light. They came in relays to the tem-

come here. This is truly the end of the world. At a 
village called Chieng or Muang Lau we crossed the 
Chinese border. I had no trouble whatever. In the
