... an extensive underlying layer of gypsum, here," he said. "The water-bearing rock. A mile away there's an ample deposit of graphite—carbon. Thus, there exists a complete local source of hydrogen, oxygen and carbon, ideal for synthesizing various hydrocarbonic chemicals or making complicated polyethylene materials such as stellene, so useful in space. Lead, too, is not very far off. Silicon is, of course, available ...

... black and transparent diamonds. This startling discovery was afterwards verified by Professors Friedel and Moissan, who found that the Canyon Diablo Meteorite contained the three varieties of carbon—diamond (transparent and black), graphite and amorphous carbon. Since this revelation the search for diamonds in meteorites has occupied the attention of ...
