In Burma, besides conducting a training college for native preachers and teachers at
Tavoy, he translated the
Bible into the two principal dialects of the Karens, the
Sgaw and the
Pwo (his translation being published in 1853), and
Matthew,
Genesis, and the
Psalms into the
Bghai dialect. He also published
A Pali Grammar on the Basis of Kachchayano, with Chrestomathy and Vocabulary (1868). In 1849, he described a new species of
pine,
Tenasserim Pine in the journal of
the Asiatic Society. In 1850 he published a book of great value on the fauna and flora of British Burma titled
The natural products of Burmah, or notes on the fauna, flora and minerals of the Tenasserim provinces, and the Burman empire. It was published by the American Mission Press at
Moulmein. An improved edition appeared in 1860 under the title
Burmah, its People and Natural Productions, and a third edition (2 vols.) revised and enlarged by
William Theobald in 1882–1883. ==Personal life==
