4,500,000 tons in 1919-1920 to 8,500,000 tons in each of the six years,
1923-1924 to 1928-1929;

(iv.) To Luxemburg, if required, a quantity of coal equal to the
pre-war annual consumption of German coal in Luxemburg.

This amounts in all to an annual average of about 25,000,000 tons.

These figures have to be examined in relation to Germany's probable
output. The maximum pre-war figure was reached in 1913 with a total of
191,500,000 tons. Of this, 19,000,000 tons were consumed at the mines,
and on balance (_i.e._ exports less imports) 33,500,000 tons were
exported, leaving 139,000,000 tons for domestic consumption. It is
estimated that this total was employed as follows:--

Railways 18,000,000 tons.
Gas, water, and electricity 12,500,000 "
Bunkers 6,500,000 "
House-fuel, small industry
and agriculture 24,000,000 "
Industry 78,000,000 "
-----------
139,000,000 "

The diminution of production due to loss of territory is:--

Alsace-Lorraine 3,800,000 tons.
Saar Basin 13,200,000 "
