236 COAL SUPPLIES 1st MAY 1949 to 30th APRIL 1950 THE quantities shown below are not "rations" that you can rely on receiving, but are the most you may buy if supplies are available. More coal and anthracite must be exported to obtain food and raw materials from abroad, so household supplies will still be scarce this year. Coke is more plentiful than anthracite, so use it if you can. Summer supplies are for winter use, except for essential cooking and water heating, and not for heating rooms in summer.
