THE IRON AGE VOL. CVII JANUARY—JUNE, 1921 NEW YORK: IRON AGE PUBLISHING CO, 239 West 39th Street CHEMICAL LIBRARY cueM, UBRAS TABLE OF CONTENTS - - - 83 Established 1855 NEW YORK ‘JAN 8 1924 January 6, 1921 Nineteen Twenty-one 1 ' OF Uelling DdcR Two years ago the people of this country thought they were facing an early readjustment from war-time conditions. Today they know that they have spent two years in merely starting on the task. It took all of 1919 to make it plain that having just finished destroying kaiser autocracy in Europe, they would not tol- erate labor union autocracy at home. Policemen at Boston, railroad workers, coal miners, steel strikers, all in turn got that answer. It wasa yeat’s work well done and worth all it cost. Nineteen-twenty brought the great strike of the American people against war prices—joint product of extravagance, speculation in commodities, sellers’ profiteering, and the de- lusion that high wages and low performance make a worker’s a ET oe paradise. And the people have been winning their strike. In 1921 we must get back to the old ways of economy and thrift. Performance must bear a just relation to pay. Those who work for wages and those who sell the workers’ product must do their part in setting prices to rights. It will take | time and patience. But every day will bring the country a little farther on its way back to economic health. That is | ground for optimism and that is why industry can face the problems of 1921 with good courage. 2 THE IRON AGE January 6, 1921 (0) > t RS: RIGNGULAR FLUED COMBINATION I OKE AND GAS OVENS.
