the day time. According to the general account of the natives, it 
hardly ever goes off the hiils except when moving from a hill to a 
neighbouring one. Iam inclined to doubt this as I have found its: 
tracks in a clearing near the Prasak river a few miles north of Saraburi 
about half way between the hills and the river, which are there some 
two miles apart. I have also. found its tracks in the paddi fields about 
half a mile from the hills near Na Yang in Petchaburi, and I have: 
always been of the opinion that it only makes such expeditions at 
night,.and then probably in search of water. I have been informed 
by Dr. Smith, however, that the Serow at Koh Hlak, when he was 
there in November 1912, regularly came off the hill in the early 
morning, and again im the afternoon as early as 4 p. m., and fed ina 
clearing at its base, with a couple of Chinamen often at work within 
200 yards of them. One was shot feeding in a plantation by the sea- 
shore, at least, 400 yards from the hill and within 100 yards of Mr. 
Butler’s bungalow. The particular hill referred to is fairly thickly 
covered with vegetation at its base, much less so near the summit. 
In every place where I have heard of Serow, except im the 
neighbourhood of Koh Hlak, there was at all events some possibility 
of their finding water in order to get an occasional drink. They cer- 
tainly cannot need much water, however, and must be able to do with- 
out it for considerable periods. At Koh Hlak, for instance, I must 
say I do not understand how they can get anything to drink in the dry 
season, but the natives there have settled the question to their own 
satisfaction ; they say the animals drink seawater. 
I consider the flesh of the Serow very palatable ; it is dark 
coloured and tastes not unlike good tender beef. 
The Serow moves fairly fast on hills, but carefully as a rule, and, 
going down hill often appears to be getting along slower than it really 
is, owing to its habit of looking before it leaps. The article in the . 
Badminton Library on this animal says that ‘‘the Serow’s chief accom— 
“plishment is the way he can gallop down a steep hill, and as he 
“invariably takes that course when disturbed, he can be easily driven, 
“provided the ground is well known.” My experience is almost 
entirely the opposite of this, as 1 have found that it always seeks the 
high tops of the hills when driven. Going up hill it does not seem to 
bound or jump or gallop, but goes rapidly upwards in a sort of even 
ranning scramble, dodging obstacles and giving one the impression
