Government Control Of The Coal Industry Was Assured By Congress By The Food And Fuel Control Act (Known As The Lever Act), Approved By The President On August 10, 1917 And On August 21, 1917, Fixed Bituminous Prices For Coal Were Announced. "The General Principles Governing The Prices In Normal Times ...Continued To Operate Through 1916 And Until The Middle Of 1917, Although In The Latter Part Of This Period Conditions Were Far From Normal. A Tremendous Increase In Demand, Which Began In The Last Quarter Of 1916 And Extended Through 1918 Until The Armistice Was Declared In November, Brought Forth An Increase In Production To A Point Where The Limit Of Railroad Capacity Was Temporarily Reached With The Demand Still Unsatisfied. Because The Demand Could Not Be Fully Satisfied, Prices In The Fall Of 1916 And In 1917 Rose To Almost Unheard Of Figures, Until First Voluntary And Then Later Government Control Was Exercised."
