A hiking pal came across this boundary stone at Sze Tau Leng 獅頭嶺，Fanling the other day. In the 1952 map, this place was called Kwai Tau Leng, the namesake for the peak nearby as is called today.
Looks like it has the words " Forestry Lot no. 125" inscribed on it. The first letter of the first word is missing, so it's just a wild guess.
It's not near the reservoir nor catchwater.
Is there any other bs of this type in HK and what is the purpose of forestry in this area at that time?
