R. H. Harrild have obtained an English patent for a method of reducing the glue to a proper state for combining with molasses and the other ingredients usually employed in the manufacture of the printers' rollers composition, without soaking it in water, in order that the glue may be obtained as free from water as possible. Instead of soaking the glue in water previous to melting it, it is subjected to a high degree of steam pressure in an enclosed vessel, so as to convert it into a jelly-like mass, above which the condensed steam will float, unmixed with the glue. The water is drawn off by any suitable means, and the composition is finished in the ordinary manner.
