were ignorant as to its true position, nor could we even ascertain
which of the rivers was the Lachen.* [The eastern afterwards proved
to be the Lachen.] The only routes I possessed indicated two paths
northwards from Lamteng, neither crossing a river: and I therefore
thought it best to remain at Zemu Samdong till provisions should
arrive. I accordingly halted for three days, collecting many new and
beautiful plants, and exploring the roads, of which five (paths or
yak-tracks) diverged from this point, one on either bank of each
river, and one leading up the fork.

On one occasion I ascended the steep hill at the fork; it was dry and
rocky, and crowned with stunted pines. Stacks of different sorts of
pine-wood were stored on the flat at its base, for export to Tibet,
all thatched with the bark of _Abies Brunoniana._ Of these the larch
(_Larix Griffithii,_ "Sah"), splits well, and is the most durable of
any; but the planks are small, soft, and white.* [I never saw this
wood to be red, close-grained, and hard, like that of the old Swiss
larch; nor does it ever reach so great a size.] The silver fir
(_Abies Webbiana,_ "Dunshing") also splits well; it is white, soft,
and highly prized for durability. The wood of _Abies Brunoniana_
("Semadoong") is like the others in appearance, but is not durable;
its bark is however very useful. The spruce (_Abies Smithiana,_
"Seh") has also white wood, which is employed for posts and beams.*
[These woods are all soft and loose in grain, compared with their
European allies.] These are the only pines whose woods are considered
very useful; and it is a curious circumstance that none produce any
quantity of resin, turpentine, or pitch; which may perhaps be
accounted for by the humidity of the climate.
