In the case of Louis Hamilton's papers, very little preliminary work had been done except on his letters home. As many of his later correspondents are still alive these private papers (after 1918) are not avaliable for public inspection. His official papers have been roughly arranged in chronological order. The very large collection of photographs has been examined in detail. In all cases letters written home have been listed under the name of the writer, instead of the recipient to whome they properly belong.
