In January 1914 I started on my second journey to Siam in order to collect various 
kinds of Natural History specimens for the Royal Natural History Museum of Stockholm. 
At the middle of February 1914 I arrived at Bangkok after a nice journey on the 
»Kleist», a steamer of the North German Lloyd. 
In Bangkok I stopped for some weeks and then on the 10th of March I left for the 
north of Siam where I intended to spend a considerable time. After about two days 
railway journey I arrived at Pak Tha, a small village situated on about Lat. N. 18°.

Pak Tha was then the terminus of the Northern Railway which is being built up 
to Chieng Mai, the most important town in the North of Siam and formerly the capital 
of the Laos country. At Pak Tha I only stopped for a few days and had some collecting 
in the neighbourhood. The forests here chiefly consisted of dry mixed forests, the fauna 
of which was about the same as that one at Den Chai, a place situated further south and 
where I spent some weeks during my former journey 1911—1912. 
I left Pak Tha on the 13th of March with a construction train which could take 
me as far as to the neighbourhood of Pak Koh which then was the centre of the railway 
building on this part of the line and the residence of a Divisional Engineer. At Pak Koh 
I stopped for more than one month and several interesting and rare species were collected 
in the surrounding jungles, the natural conditions of which were very variable. The 
mixed dry forests are, however, the most predominant in the low-lying country and on 
the lower hills. In the valleys and along the numerous small creeks evergreen jungles 
occur though sometimes mixed with bamboos.
