Letter from Thomas Gold to Professor Harry Messel, Head, School of Physics, University fo Sydney, Sydney, New South Wales, Australia Is sending him a copy of his magnum opus. Not yet published, so he is to consider it for personal information at present. He will see that there are still tremendous possibilities for fuels on this little planet, and also earthquakes and tsunamis now have a reasonable explanation. Glad to hear his solar work is going well. Asks him to send Gold the progress reports. 6 February 1978
