Photomicrography as Applied to Timber Study. 

 By W. S. Jones, M.A., M.Sc. (Plate XIII.) 



(Read 12th March 1914.) 



Those who have had some experience in the study of 

 the minute structure of timber know all too well the many 

 difficulties of representing by drawing the complex anatomy 

 of dicotyledonous timbers. These difficulties are, without 

 doubt, best overcome by invoking the aid of the camera, 

 and } 7 et how seldom is the art of photography practised in 

 relation to the study of timber structure ! Besides being a 

 convenient method of illustration, it is, above all, accurate, 

 entirely eliminating, as it does, the personal element. 

 Imagining the work to be such as can only be conducted 

 in well-equipped laboratories, students leave our colleges 

 for work in forest areas in the colonies and elsewhere 

 deprived of one of the greatest helps in the field of timber
