Abstract
THE preface to this memoir refers to the great advantage which the glass industry of this country is deriving from the prescient policy of the Department of Optical Munitions and Glassware Supply of the Ministry of Munitions; and the memoir itself is an example of the department's effoits to place the industry in a sound position. A knowledge of the home resources of raw materials is of prime importance to the glass industry, and the exhaustive survey made by the author has enabled him to place on record for the first time valuable information as to the resources of suitable sands on which the glass manufacturer can rely. In pre-war days large quantities of excellent sand were imported from Belgium and France, and their cheapness was mainly due to their transport as ballast in coal-boats. Economic conditions may prevent the utilisation of many of the occurrences of sands and rocks to which the memoir refers, but rmjch will depend on the provision of cheap transport by the adequate development of our canal systems. This is well shown by the sketch-map marking the locations of the chief resources of glass sands in relation to the glass-making areas.
