|The mission books from January 1868 consist of gatherings bound into volumes. The copying clerks wrote gathering by gathering, so that the handwriting and the individual items may be split between gatherings.
The letters and journals from 1820 to November 1836 are copied out in full, while a note of receipt is often made for the financial papers [returns, accounts etc], as distinct from the finance letters. Journals are not copied after November 1836, nor reports after 1838. From 1838 to 1841 the volumes include lists of items not copied in full and from 1843 only letters are fully copied Annual letters from those for 1875 onwards, are copied out in [or, if printed, pasted or sewn into] the backs of the volumes. These letters are a yearly account by missionaries of their activities and cover a period from August to July.
