On tlie loth March 1912 I left ni}' headquarters camp with 

 20 coolies and, crossing a low ridge, slept that night at a big rock pool 

 in the Huey Ma Rew, a favourite liatint of langin-s, and attracted by 

 tlie excrement of tliese, or some other cause, numbei less flies kept up a 

 humming as of swarms of bees till nightfall and started again at 

 dawn. In the previous year a herd of sladang haunted this pool for 

 some months : and on one occasion while we were improving the game 

 track to make it serviceable for mail transport, a sladang waited at the 

 side of the path watching me till I approached within 10 yards. The 

 first intimation I had of its presence was when, whirling round, it 

 dashed up the hillside. At other times I have found them lying down 

 during the heat of the day on the more open knolls of a hillside, and 

 on such occasions they go crashing down to the vallej's before one gets 

 near them ; and the fact of this beast waiting is probably attributable 

 to the haphazard and " doing nothing in particular" manner of my 

 approach. 



Following the stream to its source, the path ascends steeply and 

 crosses the rather flat watershed between tlie Ma Rew and Maa La 

 Liang valleys at an elevation of some 450 metres. I found the bed of 

 a small dry stream crossing the path to be much encrusted with a 

 deposit of lime several inches in thickness, and more especially of 

 course where the water had trickled down small declivities. In the 

 previous year I saw on this path a large family of the big muscular 

 Stump-tailed Macacques — never found outside the evergreen jungle 

 and usually at some elevation. In 1911 I obtained a young one 

 dropped by his mother in her flight, and this I kept till it died of sun- 

 stroke during the present year. 



Contiiiuing along the well defined g'ame ti'ack, the path descends 

 at an eas}" slope to the Huey Maa La Liang. This stream has its 

 source at the base of a mountain range surmounted by a grass covered 

 peak some 1250 metres in height, and is the only mountain within a 

 radius of ten miles with a name to it (Kao Pa Nern Toong). In the 

 previous year the valley was inhabited by a Karang and his family, but 

 in April the wife and daughter fell ill with cholera, and the husband 

 fled leaving them to die and their bodies to dry in the sun. In cases 

 of cholera and small pox, Kariangs and Karangs immediately flee^ 

 forming new settlements elsewhere, but I believe as a rule bury their 

 dead. In 1912, small pox broke out in my headquarters camp, and
