                  General review of the coal question, the following being briefly considered:  (a) General methods for the chemical utilization of coal including high- and low-temperature carbonization, hydrogenation, reduction of CO with Badische Anilin- und Soda-Fabrik patents of 1913-1914, synthesis of MeOH.  Patart’s patent, Fischer-s synthol, Fischer’s and Tropsch’s hydrocarbons, Kling and Florentin’s process, and Bergius process; (b) N2 question including preparation of (NH4)2SO4 from gypsum, mixed fertilizers, (NH4)2-HPO4, and Claude’s “potazote;” (c) the general organization for fuel and synthetic NH3 manufacture, with some Norwegian, Italian, German, and French financial data.
