Labor, invited him to become a commis sioner with the Conciliation Service, U. S. D e p a r t m e n t of Labor. As a commissioner a n d later as Director of Conciliation (1934-^4) Dr. Steelman constantly impressed people with whom h e came in contact in settling labor disputes t h a t " I t ' s j u s t smart to get along t o gether." D u r i n g this period h e super vised in t h e settlement of 80,000 labor disputes, m a n y of which never reached t h e public eye. Following his resignation from t h e C o n ciliation Service in 1944, h e entered p r i v a t e practice as a public relations con sultant in New York, b u t in less than a year President T r u m a n recalled h i m to t h e Government a s special assistant to t h e President in charge of labor m a t t e r s . I n 1946 he succeeded J o h n W. Snyder a s reconversion director a n d was later a p pointed Director of Economic Stabilization, succeeding Chester Bowles. After recom mending t h a t these offices be discontinued a t t h e end of 1946, he was a p p o i n t e d Assistant t o t h e President with general duties of coordination a n d liaison. He is t h e first to hold this title.

scribed in eight reports. T h e Desmodurs are formed b y reacting diisocyanates and polyisocyanates with polyhydroxy com pounds. I n general, di-compounds form linear polyurethanes while tri- a n d higher compounds form cross-linked products, making it possible t o produce an infinite variety of properties by suitably varying constituents. PB-1336, s t u d y of new adhesives, (mimeographed, 50 c e n t s ; 13 pages) discusses t h e properties of Desmo dur R . PB-19S5S, manufacturing process for Desmodur R (mimeographed 25 cents; 8 pages) describes t h e production of this adhesive. PB-27521 (mimeographed, 25 cents; 9 pages) reports on German production practices in using D e s m o d u r R as a bonderizing agent between tire cord fabrics and their rubber coatings. PB-28835 (mimeographed, 50 cents; 86 pages) is primarily a discussion of Ger man synthetic tire production. PB-192 (mimeographed, 75 c e n t s ; 117 pages) is concerned mainly with a dis cussion of production processes employed by t h e Phoenix firm in making tires and tubes, conveyor belts, hose, shoes, surgicals, and other rubber items. Three reports discussing development of Desmodurs are: PB-45246 (mimeo graphed, 25 cents; S pages) relating infor mation on t h e chemistry of isocyanates and particularly t h e new polyisocyanates and their derivatives which h a v e been intensively studied in Germany for some years. PB-60908 (mimeographed, 25 cents; 4 pages). A few notes are given on t h e manufacture of Desmodur Τ by t h e phosgenation of tolylene diamine hydrochloride, the conversion of Desmodur Τ to Desmo dur T H by a trihydroxy alcohol, the Desmodur-Desmophen reaction, a n d t h e mold ing powders m a d e from diisocyanate products. PB-185 (mimeographed, 25 c e n t s ; 11 pages) gives information on isocyanate polymers produced b y the Elberfeld and Leverkusen plants.
