Helped by my two servants, who sat by me to keep watch and to screen me, I managed, at considerable risk, to keep a rough record of the journey back, on a small piece of paper that had remained in my pocket when I had been searched by the Tibetans. As I did when on the rack, I used to draw my right hand out of its cuff, and, with a small piece of bone I had picked up as pen, and my blood as ink, I drew brief cipher notes, and a map of the whole route back.
Necessarily, as I had no instruments with which to take careful observations, I had to content myself with taking my bearings by the sun, the position of which I got fairly accurately by constantly watching the shadow projected by my body on the ground. Of course, when it rained or snowed, I was altogether at a loss, and had to reckon my bearings by the observations of the previous day.
CHAPTER XCIV
South of the outward journey—Severity of our guard—Ventriloquism and its effects—Terrible but instructive days—The Southern source of the Brahmaputra—Leaving Yutzang.
We travelled, as can be seen by the dotted red line on the map attached to this book, first W. then W.N.W., N.W., W. and N.W., following the Brahmaputra along a course South of the outward journey, until we reached the boundary of the Yutzang[37] (central, or Lhassa) province. Our guard were not only severe with us, but they also ill-treated us in every possible way. One or two of the soldiers, however, showed kindness and thoughtfulness, bringing us a little butter or tsamba whenever they could do so unseen by their comrades. The guard was changed so frequently that we had no chance of making friends with them, and each lot seemed worse than the last.
A very curious incident happened one day, causing a scare among them. We had halted near a cliff, and the soldiers were some twenty yards off. Having exhausted every means I could think of to inspire these ruffians with respect, I resorted to the performance of some ventriloquial feats, pretending to speak and to receive the answers from the summit of the cliff. The Tibetans were terror-stricken. They asked me who was up there. I said it was some one I knew.
"Is it a Plenki?"
"Yes."
