THE BIRDS OF NORTHERN THAILAND 6 



not until August 18 that he was able to set out, accompanied by 48 

 bearers, for Chiang Mai, via Wiang Pa Pao. Almost exhausted, he 

 reached his destination on August 26 and rested there until September 

 2. He next returned to Khun Tan where he was to work until about 

 the 25th. Then going back to Chiang Mai he engaged boats to trans- 

 port him down the Mae Ping to Pak Nam Pho and, on October 2, set 

 off for Central Thailand and the upper part of the Malay Peninsula. 



The valuable collections that resulted from the expedition were de- 

 posited in the museum at Stockholm.

At the time of Gyldenstolpe's expedition of 1912, the Northern Line 

 of the Royal State Railways extended no farther than Mae Phuak. 

 The German divisional engineer in charge of construction, Emil, 

 Eisenhofer, had his bungalow at Ban Huai Horn, and Gyldenstolpe 

 stayed with him during the month of February, working out in all 

 directions from that locality. Eisenhofer had already, as early as 

 1910, began to collect bird skins, sending specimens, with no more data 

 than "Siam" and the year, to the museum at Munich. Evidently as 

 a result of Gyldenstolpe's visit, he became much more active as a col- 

 lector and began, at least on occasion, to write full information on 

 his labels ; the earliest of such specimens date from February 7, 1912.
