"You must not shoot," said he, with his usual calmness; "you might kill somebody." "I only wish to teach these cowards a lesson." "That is all very well. But every man in Tibet is so cowardly that the lesson would have to be constantly repeated," answered Wilson with his perpetual wisdom. I slung my rifle over my shoulder and made up my mind to start some other time on the cyclopean task I had then so nearly begun. When we had covered a mile or so of the plain, our phantomlike escort crossed the pass, and came full gallop down the hill. I gave orders to my men to halt, seeing which, the soldiers also came to a dead stop. I watched them through the telescope. They seemed to be holding a discussion. At last five men rode full speed northwards, probably to guard the track in that direction. Three men remained where they were, and the remainder, as if seized by panic, galloped frantically up the hill again, and disappeared over the summit. We resumed our march. The three horsemen followed a course one mile south of ours, close against the foot of the hills, and lying low upon their ponies' heads, they probably imagined that they were passing us unperceived. Seeing that our bearings were for our old camp at Lama Chokden, they left our line and rode ahead of us. When in the evening we reached Lama Chokden, two shepherds came to greet us. Then another appeared. "Our sheep are far away," said they. "We are hungry. We are poor. Can we stop near your camp and pick up the food that you will throw away?" "Certainly," I replied. "But mind you do not pick up anything else." These simple folk, thinking I should not know them, had left their ponies at the Lama Chokden guard-house, and, disguised as shepherds, they were now trying to ingratiate themselves with us, with the object of discovering our movements and plans. They were, of course, no other than the three sepoys from Gyanema. At each step in our retreat towards the Himahlyas my heart became heavier and my spirits more depressed. I was full of stratagems, but to think out plans and to carry them into effect were two different things. How many times had not my schemes been upset? How often had I not had to begin afresh when all seemed ready and in perfect working order?--that, too, when I had plenty of good material at my disposal to work upon. Now things had changed altogether for the worse. My chances of success, notwithstanding my incessant struggle, were getting smaller and smaller every day. I could not but feel that there must be an end eventually to the capability and endurance of my followers and myself. It is hard enough to start on a difficult task, but when you are well started, and have already overcome many difficulties, to have to come back and begin again is more than galling. The outlook was dark and gloomy; I stood face to face with apparent failure, and I was uncertain of the loyalty of my own men.
