"t'hlo" a hill in Lepcha.

Isolated patches of vegetation appeared on the top of the pass, where
I gathered forty kinds of plants, most of them being of a tufted
habit characteristic of an extreme climate; some (as species of
_Caryophylleae_) forming hemi-spherical balls on the naked soil;
others* [The other plants found on the pass were; of smooth hairless
ones, _Ranunculus,_ Fumitory, several species of _Stellaria,
Arenaria, Cruciferae, Parnassia, Morina,_ saxifrages, _Sedum,_
primrose, _Herminium, Polygonum, Campanula, Umbelliferae,_ grasses
and _Carices_: of woolly or hairy once, _Anemone, Artemisia,
Myosotis, Draba, Potentilla,_ and several _Compositae,_ etc.] growing
in matted tufts level with the ground. The greater portion had no
woolly covering; nor did I find any of the cottony species of
_Saussurea,_ which are so common on the wetter mountains to the
southward. Some most delicate-flowered plants even defy the biting
winds of these exposed regions; such are a prickly _Meconopsis_ with
slender flower-stalks and four large blue poppy-like petals, a
_Cyananthus_ with a membranous bell-shaped corolla, and a fritillary.
Other curious plants were a little yellow saxifrage with long runners
(very like the arctic _S. flagellaris,_ of Spitzbergen and Melville
Island), and the strong-scented spikenard (_Nardostachys_).

The rocks were chiefly of reddish quartz, and so was the base of
Chomiomo. Kinchinjhow on the contrary was of gneiss, with granite
veins: the strike of both was north-west, and the dip north-east 20
degrees to 30 degrees.

We made a fire at the top with sheep's droppings, of which the Phipun
had brought up a bagfull, and with it a pair of goat-skin bellows,
