"Well, young fellah," said he, "who would have thought of meetin' you up here?"
"What in the world are you doing?" I asked.
"Visitin' my friends, the pterodactyls," said he.
"But why?"
"Interestin' beasts, don't you think? But unsociable! Nasty rude ways with strangers, as you may remember. So I rigged this framework which keeps them from bein' too pressin' in their attentions."
"But what do you want in the swamp?"
He looked at me with a very questioning eye, and I read hesitation in his face.
"Don't you think other people besides Professors can want to know things?" he said at last. "I'm studyin' the pretty dears. That's enough for you."
"No offense," said I.
His good-humor returned and he laughed.
