ACROSS THE SATSCHU-TSANGPO AND BACK AGAIN. 507
on we overtook the caravan. The footprints of the animals made big gaping holes in the mire and were all filled with yellowish-red water, the colour being due to the red sandstone which was here everywhere predominant. The surface was now relatively level. We still had a mountain-range on our right, and off it the brooks
were running north-east down towards the river I have mentioned. We passed next an encampment of three Tangut pilgrims from Kum-bum. They had with them 50 sarliks (a cross-breed between the yak and the ordinary ox), a couple of horses,
and dogs, and were on their way to Lhasa.
