po Mr. Saunders’s Account of the 
pices, and huge ftones. Here we begin to experience a very 
confiderable change in the temperature of the atmofphere ; 
the furrounding hills were covered with fnovv in the morning, 
which had fallen the preceding night, but difappeared foon 
after fun rife. The thermometer fell to 54 0 in the afternoon, 
and did not rife above 62° at noon. 
The face of the mountains, in fome places bare, with pro- 
jefting rock of many different forms ; quartz, flint, and a ^ad 
fort of freeftone, common. Many very good fprings, (lightly 
impregnated with a felenitic earth. 
The foil is rich, and near to the river in great cultivation. 
Many horfes, the ftaple article of their trade, are bred in this 
part of the country. Found walnut-trees, peaches, apples, 
and pears. 
Road to Sanha, Sept. 12. The road (till afcending to

The thermometer falling fome degrees, we found it cold and 
chilly. The bed of the river is full of large ftones, probably 
waftied down from the mountains by the rapidity of its ftream; 
they are chiefly quartz and granite. Here is excellent pafture 
for numerous herds of goats. 
Road to Chichakumboo. From Sanha the afcent is much 
greater, and, after keeping for ten miles along the banks of 
the Pachu, ftill a confiderable dream, we reach its fource 
(from three diftinit rivulets, all in view, ramified and fupplied 
by numerous fprings), and foon after arrive at the moft ele-

Here we quit the boundary of Boutan, and enter the terri- 
tory of Thibet, where nature has drawn the line ftill more 
ftrongly, and affords, perhaps, the moft extraordinary con-
