But parenthetically, might said that these rather important qualifications have been overlooked number investiga- tions which have been obviously tinged with partiality motive. The point wish bring out this matter that turn about fair play. Under our constitution and land where government the servant and not the master the people, private citizens have just much right investigate government, these same terms, govern- ment has investigate them. And such investigations made qualified people and resulting constructive criticisms might salutary. Gaston DuBois, the distinguished vice-president the Monsanto Chemical Company, exposed this thought his address before the Society Chemical Industry recently. Speaking the occasion the award him the Perkin medal for outstanding service applied chemistry and with special reference our chemical scientists, sug- gested that might good thing for committee chemists, chosen from private industry investigate government chemical research proj- ects and report upon the desirability the projects being undertaken well upon the efficiency with which those already underway completed have been conducted. The thought expressed Mr. DuBois applicable, course, not only chemical research under government auspices but also all in- dustrial and business activities which government participates. Ap- plied the field metallurgy certainly would have killed embryo the project that fathered rather mothered the metallurgical monstros- ity known the Lincoln penny. That this would have been public interest something one can dispute. Unfortunately there established procedure whereby such com- mittees could set except informally and they would lack the power subpoena. However, this lack would offset the publicity that would naturally given recognized experts reporting matters public interest. Perhaps this thought can translated into action some our professional societies and industrial associations.

Despite the shortages man- power, equipment, and materials which beset all industry today, American railroads continue handle the load placed upon them. Freight traffic 1943 amounted 725 billion ton-miles—14 per cent above 1942, and passenger traffic 1943 increased bil- lion per cent more than 1942. Facilities were stretched what seemed their limit meet the demands 1942. Yet 1943 the increased traffic was handled with less than one per cent more freight cars, and with practically the same number pas- senger cars.
