WASHINGTON--President Roosevelt, appealing for national support for his drastic anti-inflation program, said tonight the price for civilization must be paid "in hard work and sorrow and blood," and declared "this price is not too high."

He promised in a fireside chat which was broadcast throughout the world, that he will use all the executive power at his command to carry out the seven-point anti-inflation and war economy policy which he submitted to Congress Monday and which he restated tonight as necessary to avert economic disaster.

He made a direct appeal over the heads of the representatives of special groups--the farmers, laborers and business men--to cooperate in the supreme economic effort. And he pledged that the Allied war effort will not be impeded by the "faint of heart," by "bogus patriots," and "by a handful of noisy traiters."
