But, exposed as the Boardmans were to perils of this kind, they continued their work among the rapidly increasing population, and met with considerable success. Many native Christians, converted under Mr. Judson at Rangoon, lived at Moulmein, and consequently the Boardmans' work was not entirely among the unconverted. Indeed, before long nearly all the native Christians in Burma were residing at Moulmein, Amherst having declined in public favour. When the majority of the inhabitants of Amherst migrated to Moulmein the missionaries accompanied them, and soon nearly all the missionaries to Burma were working in one city. Neither the missionary board in America nor Mr. Judson considered this to be wise, and some of the missionaries were removed to other places, Mr. and Mrs. Boardman being sent to Tavoy, some 150 miles south of Moulmein. The dialect of the people of Tavoy differed considerably from Burmese, and the Boardmans had practically to learn a new language. As the written characters of both languages were the same, the task was not very difficult, and before long the missionaries were preaching the Gospel to the Tavoyans. Soon after they had settled down some Karens invited Mr. Boardman to visit them. Their country was not far away, but the missionary could not as yet leave Tavoy. The Karens, however, told him something that excited his curiosity. A foreigner passing through the land had given them a book, and told them to worship it. They had done so. A high-priest had been appointed, and he had arranged a regular form of worship, Mr. Boardman asked the Karens to let him see the book, and they promised to bring it to him. Soon a deputation, headed by the high-priest, attired in a fantastic dress of his own designing, arrived at Tavoy with the book, which was carefully wrapped up and carried in a basket. On having the book handed to him Mr. Boardman saw that it was a Church of England Prayer-book. He told the Karens that although it was a very good book it was not intended to be worshipped, and they consented to give it to him in exchange for some portions of Scripture in a language they could read. It was never discovered who gave the Prayer-book to the Karens, but it may be taken for granted that they misunderstood the donor's meaning. This book was afterwards sent home to the American Baptist Missionary Society.
