ETHYL CORPORATION IXTER-OFFECE CORRF.SFO N EXCE TO Dr. B. A. Kehoe a d d r e s s Cincinnati from J. E. Boudreau a d d r e s s Hew York SUBJECT DATE April l8, 1966 Dear Bob: I have your letter regarding the White Horses. Please have no fear that you are in any way being a nuisance to me. In view of the fact that my contacts are in Washington and your date isn't until September,, X am going to see my friends there when I am down for the lead investigation in May. This will still give ample time. If that falls through, I now have another lead. On Saturday we in vited some new neighbors to the house for a drink. Both the man and his wife are Swiss and he is a doctor with the Rockefeller Foundation. He is quite an avid horseman, and both he and his wife keep horses at the Hunt Club in Darien. In the course of the conversation he mentioned that they were going to Vienna next month and were particularly interested in the White Horses. I remarked that this was rather a tight proposition with all the tourists today. He said that he had no problem because the head of the Spanish Riding School was a very close friend of his and he has visited them a number of.times. So I am sure that one way or the other, I can^get you, your wife and Kathleen in. I talked with Dick Scales this morning and he said he had outlined to you the nature of our appearance on the 26th. In view of the fact that on that same day they are throwing in sulfur, boron and a number of other things, I am very hopeful that we will be lost in the shuffle. One of the remarks dropped was that all presentations should not be longer than 10 minutes. I don't think that should cause you too much concern for I am sure that George Kirby will be glad to relinquish part of his time if it is necessary. . -^ ^ O' I am attaching a copy of the boiled down version of your original V/tr . paper. Although I understand you are working on a new version, I think that ; W- - h the attached version, which can-in turn be greatly reduced, might give a very \good overall background of the situation. At any rate, I would be most happy v'\ tl/' T 1^ to work with you as soon as you let me know. wyTi v With the kindest regards, .* cerely, hr JEB:w James E.
