Although the above paragraphs were written some months ago, the recommendations contained in them are the ones I would urge you to consider at the present time. In conclusion, I should like to repeat the offer made at the end of my letter of February 20 to Dr. Wyckoff, namely to serve, if needed, as consultant on the green fireball project as suggested in Major Oder's letter to me under date of November 29, 1949, with the stipulation, however, that my service be on a voluntary basis rather than on the $40 per day contract specified in Major Oder's letter.
