 Is Herrell as intelligent as Hatcher? Why or why not?
Hatcher was not exactly male, because his race had no true males; but it did have females and he was certainly not that. Hatcher did not in any way look like a human being, but they had features in common. Hatcher, like McCray, was an adventurous soul, young, able, well-learned in the technical sciences of his culture.
