First edition, first impression of this introductory work on geological maps by one of Britain’s first professional female geologists and university lecturers. A very attractive copy. With the blindstamp of Maine State Geologist J. C. Twinem.
Gertrude Elles (1872-1960) was a star student of Newnham College, Cambridge during the 1890s, eventually becoming their lecturer in geology, the first woman university reader (in 1936), and after her retirement the first woman to hold the position of Reader Emeritus at Cambridge. “Under the supervision of Professor Lapworth of Birmingham University, Elles studied graptolites [Cambrian period fossils similar to present-day corals] and their use in the stratigraphy of the ordovician and Silurian rocks of the Welsh Borderland and Wales. By the time she was thirty years old, she had begun the publication with E. M. R. Wood of the monumental Monograph of British Graptolites. This monograph formed the basis of the work on British graptolites for years to come... Although she is best known for her studies of graptolites, she also worked on metamorphism and the structure of the Precambrian rocks of the Scottish Highlands” (Biographical Dictionary of Women in Science, p. 418). In 1919 she became one of the first group of women elected to the Geological Society of London, and also the first female recipient of the organisation’s Murchison Medal.
In the introduction, Elles writes that this volume is “based mainly upon the notes for a course of lectures and practical work given to many successive generations of Girton and Newnham students. I was asked to put the subject matter into the form of a book in order that it might be available for other students of Geology”.
