Chemists also confirmed the possibly volcanic character of many of the lunar samples. The minerals that they have already identified include feldspar and olivine-both found on earth. Other information came by radio from the lunar surface itself. Despite fears that the intense heat of the two-week lunar day might ruin its intricate mechanism, the seismometer left behind at Tranquillity Base continued to function, recording more than two dozen "seismic events." Some of the tracings seemed remarkably like shocks recorded during quakes on earth. Other signals pointed to the possibility of lunar landslides, set off in crater walls...
...Doors. International Minerals, which once concentrated on phosphates for fertilizer and cattle feed, now makes 20 different products that have boosted sales from under $12 million to $88 million in 1953, with profits of $7,000,000 (up 5,500%).

It would take him 30 years, he guessed last week, to whittle Crazy Horse...
