Returning to his former position on April 20, 1935, and with finan- 

 cial assistance from the United States National Museum, he collected 

 extensively throughout the northern provinces (and elsewhere) until 

 April 15, 1937, sending all zoological material to the Museum at 

 Washington. During this time he had the full-time assistance of the 

 Chinese collector Charles Tan (known also as L. K. A. Charles).
