6 NILS GYLDENSTOLPE, ZOOLOGICAL RESULTS OF THE SWEDISH ZOOLOGICAI EXPEDITIONS TO SIAM. 
On the 16th of April I left Pak Koh for Koon Tan, a small place situated among 
the mountains locally known as Loi Koon Tan. A great tunnel is here being made for 
the railway and the Divisional Engineer Mr. Emin E1s—EnHoFER who was in charge of 
the building had kindly invited me to spend some time as his guest. Mr. EISENHOFER 
is a keen naturalist and during his stay in Northern Siam he has brought together large 
collections, chiefly consisting of birds. These collections have turned out to be very 
valuable, and some reports about them have been published in various periodicals by 
the present author. 
The journey from Pak Koh to Koon Tan was made in about 5 days. The first 
days march was fairly long and I arrived at Meh Chang, a small village, late in the 
afternoon on the 16th of April. The whole days march went merely through dry forests 
with only a scanty vegetation and the bird-life was very scarce. At Meh Chang I had 
to stop one day to change carriers, and I then made some collecting in the neighbourhood. 
From Meh Chang I had one days march to Nakorn Lampang, a fairly large town 
of Northern Siam. I took my headquarter just outside the town near a small village 
called Sop Tue situated on the right bank of the Meh Wang river, which I had to cross. 
From Sop Tue I had another 46 km. to Koon Tan which I did in one day. Mr. E1srn- 
HOFER’s bungalow is situated on the top of a high hill and from the veranda there was a 
magnificent view of the surrounding country. To the north is spread the fertile Meh Tha 
valley which is bordered to the north by the high mountains which bound the large Chi- 
eng Mai plain. To the south, west and east Koon Tan is surrounded by wild mountain 
chains, the highest peaks of which are about 1500 m. The lower slopes of these moun- 
tains are covered with oak- and bamboo-forests, but the higher parts are clad with mixed 
pine- and oakforests. Sometimes these pines grow to considerable dimensions as is to 
be seen by the photo, which was taken on one of the Koon Tan hills. In the narrow valleys 
and in the numerous »hues» (= mountain creek) impenetrable evergreen jungles occur. 
The animal life was very rich and numbers of interesting and very little known species 
of birds were obtained at this locality. 
When having Koon Tan as my real headquarter I also made excursions to Bang 
Hue Pong, a small hamlet situated on the southern side of the Koon Tan pass. The sur- 
roundings of that place as well had a very interesting fauna which in several ways differed 
from that of Koon Tan. 
Another place which J also visited at several occasions was Chum Poo. That was 
the name of a village situated at the Meh Tha river. As the neighbourhood chiefly con- 
sisted of open rice-fields and dry forests, the fauna was neither very rich nor very inter- 
esting. 
At Koon Tan I stopped to the middle of June when I went up to Chieng Mai via 
Lampoon. The distance between Koon Tan and Chieng Mai is about 70 km. This journey 
may, however, easily be done in one day as the roads are quite good and between Chieng- 
Mai and Lampoon there is a broad military road where a motorbus is running. During 
the rainy season, however, even this road is very bad and then the motor traffic is often 
closed.
