Our guide, who in his time had been a salt collector, and knew the lay of the country, proved himself to be invaluable. Without him, the route we took would have been very hard indeed to find, and to him we owed the steady progress we daily made, not that we went at any rapid rate, or as a rule for any great length of time each day, but we were marching in the right direction, we were travelling east. By reason, too, of the assistance we received from the hired yak, we were able to ride ponies, and it was our wont, after starting off our sub-surveyor in front of every one else, to start ourselves ahead of the caravan, with our cook, Lassoo, likewise mounted. We carried our rifles and ammunition, while he carried in his saddlebags our cold breakfast with some tea leaves and a kettle to boil them in. As soon as we considered that half the march had been covered, we would halt by a stream, if there were one, or by a patch of snow, and boil our water. During these operations the caravan would catch us up again and march on ahead of us. In this way we were enabled to keep an eye upon our men without appearing to do so and thereby raise their suspicions.
On the third day from Niagzu we made our breakfast halt by the side of a valley close to some white stones. From this point two more lines of white stones lay at intervals, separated at an angle of some twenty degrees, and ran right away across the valley and over the opposite hills. We were told that this was a gazelle trap laid by the nomads. As soon as they can contrive to get gazelle into the space between these two lines, they drive them along between them. The gazelle being afraid of the stones continue to be driven on to where the stones meet, where they are easily captured, and sometimes a big haul is made. Although we saw plenty of gazelle about here, they were very timid, and as we had no time to go in for a recognised stalk, we shot none at this period, nor did we drive any between the two lines of white stones!
On the same evening, after crossing a waterless, stony plain for several miles, we reached Lake Treb, so famous for the salt that is taken away from its neighbourhood and carried into Ladakh. Salt, in fact, is collected from any spot within a hundred miles of Ladakh wherever it can be found. We had been marching twelve hours upon arrival at this lake, and it was already dark. Our chances of finding fresh water were very small, for our guide informed us that there was none to be had till we reached the other side of the lake, another four miles. Certainly there was no water running into the lake from this side, and the guide's statement would have been correct, had we not luckily found two small patches of snow and a little grazing close by.
