IT is with some diffidence that I comply with Colonel Gurdon's request that I should add a few words of preface and explanation to the last literary work of an old friend and pastor, whose loss will long be lamented in the Assam Valley, where he laboured as a missionary and planter's chaplain for upwards of forty years. Mr. Endle's interest in his Kachari flock was that of an evangelist rather than that of a linguist or ethnologist, and this preoccupation has colored his style and affected the matter of his book in a way that, however pleasant and natural it may seem to those who had the privilege of his acquaintance, may perhaps require a few words of explanation for the benefit of those who look for anthropology only, or linguistics, in his pages.
