Dear oot
In th tober 26th issue of the Chronicle §$

+ This article
was prepared by you. I had written tc the San Francisco
Chronicle asking permission to use it, and they suggested
that I contact the Washington Post. This I have done

and they state that there is no objection to reprint
with credit but that I should obtain permission from

you to use the article.

 

 

 
    

I am interested in sending this article to our extension
people due to the fact that there are some points that

give us a lot of food for thought during this present

period of problems on pesticides. I think your point is good
that some of our natural’ products may have certain

adverse biological effects the same as our synthetic
additives if we knew the full biological information.

I also like your statement that it would be indeed difficult
to certify a compound as safe to any extent outside our
context of actual experience and testing.

I would appreciate very much using this article as written
in the enclosed copy.

Very truly yours,
