Hope Mirrlees became a student of Jane Harrison at Newnham in 1910 at the age of 23, with Harrison approaching 60. The student/teacher relationship quickly blossomed into an intimate friendship that lasted the rest of Harrison's life. The letters and postcards show glimpses into their very private world, from the early years at Newnham to their plans to live together in Paris after Harrison's retirement. There are 145 postcards, letters, and notes, many undated; where possible dates have been assigned according to the postmark. They frequently used pet names for each other in their letters: 'EW' -- Elder Walrus (Jane Harrison), 'YW' -- Younger Walrus (Hope Mirrlees), and also included Jane Harrison's stuffed bear 'OO' -- Oldest One. See individual files for more detail, 1/3/1-7, and Series 4 for the rest of the Mirrlees papers.
