Dugan? Sees six ships scuttled without batting an eyelash, and passes out at seeing a pinprick! Aw, well, it's probably shock more than anything else. I'll unloose his shirt, give him a little air--" I said, "He's the queerest guy I ever met. But he's a man, Skipper." Then a funny thing happened. The Skipper, strangely scarlet of face, rose suddenly from Andy's side. He croaked, "You--you wouldn't like to lay a little bet on that, Dugan?" "Huh?" I said. "On what?

Well, looking back on it now I can see how we should have realized it from the beginning. Sure, Captain Slops was a girl! That high, mellow voice ... the oversized uniform coat ... that prudishness which was not prudishness at all, but understandable modesty. Later, as we were streaking the spaceways toward our Callisto rendezvous, the Leo completely repaired, we demanded and received an explanation.

"More than all right!" acknowledged the Skipper. "If it hadn't been for you--Don't worry, Miss Delaney. I'll see that the proper authorities hear all about this. Only--" A crease puckered his forehead--"There's something I ain't yet puzzled out. How come you ordered Mr. Dugan to shoot not at, but above the ships? At the Bog? And how come the rocks came tumbling down thataway?" "Why," smiled Ann Delaney shyly, "it was really very simple. Heat, Captain." "Heat?" "Of course. As any student of thermodynamics knows, heat has a definite attractive
