brought an increasingly fancy price in the jewel markets of the System. A few sizeable finds and Yancey would have a little capital with which to work. Given fifty thousand credits he was certain that he could, in time, become one of the really big investors on Venus. Such projects always assumed a false simplicity in Yancey's mind. Aboard the space tramp that brought him to Athens his sudden rise to power and position seemed quite feasible.

Do you realize, Ritter, that since we established our chain of humidi-huts on Venus we've reduced our mortality rate thirty per cent?" A nod seemed to be all that was required from Yancey. "I just want you to
