We took both the old Mūsô men as assistants, and the younger ones as carriers for our equipment. Our first day’s journey was a fair sample of what we had to do continually. In many places it would be a misnomer to speak of the track we travelled as a path. We left the plain in the morning, and it was half-past two in the afternoon when we reached the first summit. It was five o’clock when, desperate with thirst, we came upon a flowing brook. There was, then, still another hard climb before we saw our long looked-for first village ahead. And, in general, because of the habit these people have of planting their villages upon the very highest points where they can get water, the journey from one of these villages to another in plain sight, and, apparently, but a short distance away, would take hours of the hardest travel. Sometimes we would walk weary hours through rain, or through bushes as wet as rain, to visit a village; only to walk back again after sitting three hours in wet clothes trying in vain to awaken some interest in old or young. One of the most interesting, and, at the same time, one of the saddest, cases we met was that of Mûn Kamprai, the head man of a village which clearly bore the impress of his character in the intelligence and industry of its inhabitants. From opium he had kept entirely aloof until, only a few years before this time, under the stress of a severe illness, he began to take it. The poor man now realized that he was becoming a wreck, but seemed to have no will-power left to make the effort to break away from the habit. He was much interested, however, in his two fellow-tribesmen whom I had brought as my assistants; and Cha Waw’s example seemed to afford him a faint gleam of hope. If we would stop a week and teach his people, and would stand by to aid him, he would try. If successful, he would surely become a Christian—and then his village would be the one we had been hoping for to free itself from the tribal bond, and become Christian. The experiment was, indeed, pathetic. Removing all temptation, he began with a desperate determination to succeed. We encouraged him with human sympathy and the hope of divine aid. We pushed as far as we dared the use of a tonic which Dr. McKean had given me for such cases; and it aided him perceptibly. He held out manfully for several days. But, at last, in an evil hour, he could endure the torture no longer, and before we knew it, he had resumed the use of the drug. For two nights he had not slept. In his own expressive language, it was not his eyes, but his heart that could not sleep. Poor man! his sufferings must have been as near those of the infernal regions as it is possible to experience in the body. And then his absolute wreck of mind, and the contempt he felt for himself when he gave up the struggle as hopeless!
