The mission books contain copies of the original papers received at headquarters from the mission. The papers were entered into the books in the order in which they arrived at headquarters. Letters were copied in full, while a note of receipt was made for the printed papers, financial papers and some letters and from 1858 journals of missionaries. From 1870 annual letters were copied out (or if printed pasted into) the backs of the volumes. The annual letters written by the missionaries give an account of the year’s work and contain fascinating details on many topics. Each of the volumes contains an index.

Letters from missionaries and from the bishop of Mauritius; minutes of conferences and the finance committee; annual letters.
