Letter from Thomas Gold to Dr B Kursunoglu, Center for Theoretical Studies, University of Miami, Coral Gables, Florida States that the enclosed may interest him in connection with his energy symposium. Gold believes that the Earth still contains immense amounts of carbon that have not yet come to the surface, and that this is in the form of hydrocarbons or at any rate not fully oxidized carbon compounds. Perhaps they can learn how and where this comes up, and perhaps they can draw on this. States that Fred Hoyle is also very interested in this question. Postscript: asks if the Jocelyn Burnell letter was OK 22 July 1977
