The bulk of this massive collection consists of letters written by secretaries of the Board to its missionaries and others; and letters received by the Board, largely from missionaries in the field. Also included are records of organizations associated with the Board and miscellaneous manuscripts, largely personal papers and photographs of individuals connected with the Board. The chief importance of the papers probably lies in the immense amount of information--social, political, and geographic, as well as religious--which they contain about those regions of the world in which the Board's missionaries operated., This is a letter of attorney (power of attorney) signed by Claus Hinrich Thomsen, in relation to the sale of a piece of land situated in Singapore to the American Board of Commissioners for Foreign Missions (ABCFM). It states that Thomsen authorises Thomas Scott, and in the case of his not acting, then John Purvis, to act on Thomsen's behalf.
