spinulosa intermixed.

The limits of A. densa, A. spinulosa and A. pendula, Melianthus, Acer
sterculiacea, Thibaudia orbicularis, A. cedroides, Rosa microphylla,
Pedicularis, Hydrangea, Baptisia, Berberis spathulata were well
determined. They may be expressed as follows: A. densa, 10 to 13,000
feet, A. spinulosa, 9 to 10,500 feet, A. pendula, 6 to 9,000 feet,
Melanthus, 9,500 feet, Acer sterculiaceum, 9,800 to 10,000 feet,
Thibaudia orbicularis, 10,000 feet, A. cedroides, 9,000 to 9,800 feet,
Rosa microphylla, 9,800 to 13,000 feet, Pedicularis, 10 to 12,500 feet,
Hydrangea, 4 to 10,000 feet unless two species are confounded, Baptisia,
9 to 9,800 feet, Berberis spathulata, 9 to 10,000 feet.

_Jaisa_ is a good sized village for Bootan, and the houses are rather
large. We were lodged in the castle, a large building, with a capacious
flagged court-yard, surrounded by galleries: we were housed in the grand
floor of the higher portion fronting the gate. A good deal of wheat
cultivation occurs around. The village is situated in a small nullah,
surrounded on all sides by pine-clad hills. The vegetation is precisely
the same as at Juggur, with the exception of a Ligustrum, which is common
along the nullah. Larks, red-legged crows and ravens, abound here.

_March 5th_.--Our march consisted of a progress along levelish ground
up the river, occasionally rounding small eminences: we then commenced
the ascent of a ridge, the summit of which we reached about half past-
twelve. Snow is common above 9,000 feet. The descent was steep and
uninterrupted from about 2,000 feet, when we reached a small river.
Thence we ascended a little to descend again, we continued over a ravine
at nearly the same level, for some time proceeding over undulated ground:
on reaching the debouchure of the ravine into a larger one running north
and south, we commenced to descend rapidly until we came to an elevation
situated above Tongsa, to this place the descent was excessively steep.
The march was thirteen miles long, the direction west.

At a temple near Jaisa found the Juniper of Oongar in flower, and
arboreous, attaining a height of about 40 feet. The whole march up,
nearly to the summit, was through pine woods, A. pendula and spinulosa
being intermixed for some time. I noticed Primula globifera, Eucalypta,
Thibaudia orbicularis, Aruncus, Rosa ramis hispidis, Dipsacus, Prunella,
Potentilla, Gnaphalium, Sphagnum, Daphne papyracea, Tofieldia, Gau
