In August and September 1898, Dr. Denman held the first school ever held for Moosur people [in Chiang Rai, Thailand]. The Christians Moosur men came down from the mountain home for four weeks’ study in reading Laos, in singing and in learning to tell the more important events in the Life of Christ form picture charts. Each of us took a hand in this novel teaching work, and Dr. Denman was ambitious enough to attempt to translate the Lord’s Prayer into Moosur. At the end of the school the men and the charts went up the mountain to tell the rest of the Moosur men, women and children of the wonderful birth, life, death and resurrection.
