1 - This figure is from a different source than the 1,100,000-ton figure and there may be some small difference in basis.
2 - Source for all German production and consumption figure in this section is The Government Board for Rubber (Reichstelle Kautschuk) unless otherwise stated.

* - * These figures do not take into account Allied ammunition captured by the Germans or a full reckoning of German losses by Allied capture and explosions, concerning which there is no reliable information. Germany is known to have captured large stocks of nitrocellulose in France. However, the production facilities acquired in invaded countries were comparatively negligible. In France, for example, because of sabotage by French workers, the Germans never got more than 700 tons of powder production a month; in Norway, because of strikes, they got practically no production.
4 - Nitrogen as used in this report comprises all forms of fixed nitrogen: ammonia and ammonium compounds, nitric acid and nitrates, cyanamide, etc. Numerical data are based on nitrogen content.
