Thank you. ********** 1888 onwards There is reference to dividing a sheet of paper into thirds by folding in the 'Teacher's Manual for Prang's Shorter Course in Form Study and Drawing', by John S Clark, Mary Dana Hicks and Walter S Perry was published by The Prang Educational Company in Boston, New York and Chicago in 1888.
This trisection technique also appears in: 'Part 1 for Prang's Complete Course in Form Study and Drawing Books I and II' by John S Clark, Mary Dana Hicks and Walter S Perry, which was published by the The Prang Educational Company in Boston, New York and Chicago in 1890 ********** 1890 'Exercises Methodiques de Travaux Manuels' by Jean Boogaerts, which was published in Belgium and France in 1890, contains two methods of obtaining a 3x3 grid / dividing an edge into thirds. It is not clear whether the second method uses folding or whether the necessary marks are made using a pen.
********** 1893 'The Prang Primary Course in Art Education: Part 2: The Second Primary Year' by Mary Dana Hicks and Josephine C Locke, which was published by The Prang Educational Company in Boston in 1893, uses estimated division into thirds to facilitate drawing a Greek cross.
********** 1894 Division into thirds by trial and error is used to make a signal flag in an article by J Marteau in 'Manuel General de L'Instruction Primaire' of 6th January 1894.
********** 1897 The same method is expolained in 'Pliage et Decoupage du Papier' by C Savineau, which was published by Librairie Hatchette et Cie in Paris in 1897.
********** 1939 This method appears in 'Trabajo Manual Educativo' by Araminta V Aramburu, which was published by F Crespillo in Buenos Aires in 1939.
********* 1940 'At Home Tonight' by Herbert McKay, which was published by Oxford University Press in London, New York and Toronto in 1940, gives a way of dividing a strip of paper (referred to as a straight edge) into thirds by comparison by eye that two lengths are equal.
