It if; interesting to note that hio interest in Aroclors ste:.is on rceoraoeudations on page 36 of our technical bulletin 0/PE-306. I ai:i sure he is referring to our recor.uonda tlona on vapor suppression. In fact, our reco;.v.iandatlonn are based on those of the USDA scientists..at.BeltsvillcvJMd., Our bulletin CS-6, issued in March, 1961, gives full details of the researches and recon:,iet:dation3 given by the USDA workers which appeared to have been carried _ out for a period of years starting as early ns 1954. I wonder if *> now bro'd has oriren at Wri.fcnvinr* which is unf miliar with the work of their predecessors. Do you thin;: it would be worthwhile sending bulletin CS-6 to Mr. Bliekcnstaff.
