"What are they?"

"Oh, never mind what they are," said Aldo. "And I win on all the twos, and the threes, and the fives."

"No, I don't win on the fours," said Aldo. "I lose on the fours. But I win on the fives and sixes, and everything else. And, of course, fours come seldom."

"I could make the game cheaper," said Aldo thoughtfully, "by waiting, and letting the intermittences pass, and only starting my play on the twos."

"Perhaps that would be a good plan," said Nancy, with vacant eyes.

"But," said Valeria, "I thought you won on the intermittences."

"I do," said Aldo, frowning, "if they are intermittences. But supposing they are fours?"
