EXTERMINATION OF THE INVALUABLE BLIGHT- RESISTANT WILD PEAR. 
(PYRUS USSURIENSIS MAXIM.) 
Nothing could illustrate more forcibly the necessity for a quick exploration of China than 
this picture of the destruction for fuel of a grove of wild pears in Chihli Province. This 
particular species has been proved by the researches of Mr. F. C. Keimer, of the Oregon 
Experiment Station, to be highly resistant to the destructive pear-blight, or fire-blight, 
and Mr. Frank N. Meyer was authorized to secure a large amount of seed of it. Between 
the time of Mr. Meyer's first visit to this grove, nine years ago, and the date of this photo- 
graph, the Chinese have made a good beginning in the extermination of what seems 
likely to prove an invaluable wild species of pear. In order to study this and other 
Chinese species of pear and to secure a large amount of seed, Mr. Reimer has been sent 
to China to meet Mr. Meyer, who is already there. (Photographed by Frank N. Meyer,
