September 14, 1970 Hr. Clair D. Del*ong County Agent Cooperative Extension Service 7 West Fleming Avenue Lewistown, Penna. 17044 . Dear Mr. Delong: Saving returned to my desk, I have noted the report which has been sent to you, and I hasten to make certain comments. I am sure that I need not tell you that the results which have been obtained by the analyses of the four samples are highly unusual for agricultural lands. There are areas of the earth, particularly in the British Isles, which are high in lead as the result of the outcropping of generally deep layers of the earth's surface. These results, however, all of them, are distinctly unusual, and with the history of the vicinity in mind with respect to the sources of lead, they reveal an highly significant degree of contamination. I am also prepared to say that animals which for one reason or another, and in varying degrees, ingest some soil with the vegetation which has grown thereon. Horses are especially prone to this conduct, but others, cattle among them, do so especially when the growth of vegetation is thin and short. Since this day (September 14) is the day of the hearing, my remarks are a bit tardy. And yet the evidence and its meaning are so clear that this is no great loss. With kindest regards, Cordially yours, RAK:wb Robert A. Kehoe, M.D. Professor Emeritus of Occupational Medicine
