But there was more than a casual connection between the two. My labours among them increased the desire, already awakened in me, to reach the home of the race. Here was another link in the chain of providences by which I was led to my life-work. The time, however, was not yet ripe. The available force of the mission was not yet large enough to justify further expansion. Moreover, our knowledge of the Lāo country was not such as to make possible any comprehensive and intelligent plans for a mission there. The first thing to do was evidently to make a tour of exploration. The way to such a tour was opened in the fall of 1863. The Presbytery of Siam met in Bangkok early in November. I had so arranged my affairs that, if the way should open, I could go north directly, without returning to Pechaburī. I knew that Mr. Wilson was free, and I thought he would favour the trip. This he readily did, and the mission gave its sanction. So I committed my wife and our two-year-old daughter to the care of loving grandparents, and, after a very hasty preparation, we started on the 20th of November in search of far-away Chiengmai. The six-oared touring-boat which I had fitted up in my bachelor days was well adapted for our purpose as far as the first fork of the Mênam. The Siamese are experts with the oar, but are unused to the setting-pole, which is well-nigh the only resource all through the upper reaches of the river. It was sunset on a Friday evening before we finally got off. But it was a start; and it proved to be one of the straws on which the success of the trip depended. The current against us was very strong; so we slept within the city limits that night. We spent all day Saturday traversing a canal parallel with the river, where the current was weaker. It was sunset before we entered again the main stream, and stopped to spend Sunday at a monastery. To our great surprise we found that the Prince of Chiengmai—of whose coming we had had no intimation—had camped there the night before, and had passed on down to Bangkok that very morning. We had missed him by taking the canal! We were in doubt whether we ought not to return and get a letter from him. A favourable letter would be invaluable; but he might refuse, or even forbid our going. If we may judge from what we afterwards knew of his suspicious nature, such probably would have been the outcome. At any rate, it would delay us; and we had already a passport from the Siamese government which would ensure our trip. And, doubtless, we did accomplish our design with more freedom because of the Prince’s absence from his realm. It was apparently a fortuitous thing that our men knew of the more sluggish channel, and so missed the Lāo flotilla. But it is quite possible that upon that choice depended the establishment of the Lāo mission.
