Letter from Thomas Gold to Dr Stirling Colgate, Department of Physics, Los Alamos Scientific Laboratory, Los Alamos, New Mexico Thanks Colgate for setting things up for him in such a magnificent fashion. It was a delightful trip for him and he hopes it will cause some reverberations. Is enclosing the papers needed for the office work. Presumably they will send him a form to sign. He is enclosing a few items that they discussed and that may interest Colgate. Post script; Gold did not write down the name and address of the lady who works in micro-biology and who may do an experiment on methane conversion to oil and coal; Gold ought to keep in touch with her and encourage her to do it. Gold has now found a reference to a methane-sulfate microbe and that is very promising. 19 March 1979
