Journal states that the Allied Chemical & D y e Corp. i s one of all American group w h i c h is understood t o have made a contract with, the French Government for t h e importation of 25,000 tons of n i t r a t e s at the same price as that agreed upon in France's recent larger purchase from Germany. This marks a victory over the Chilean nitrate syndicate, winch apparently is continuing i t s refusal t o deliver nitrates a t that price, and also is likely to mean, the collapse o f the Chilean-Norwegian-American gentlemen's agreement whereby t h e three were united to fight French import restrictions. A renewed struggle for control of European markets would result. A T L A S POWDER C O .
