"As I was about to say when interrupted," continued Professor Zepplin, "the Black Mountains lie in Buncombe and Yancy counties—"

"Does Chops come from Buncombe?" interrupted Stacy.

"Again I say, they form a spur of the Blue Ridge," resumed the Professor unheeding the interruption, "and are a part of the Appalachian system. They lie between the French Broad River and its main tributary, the Nolichucky."

"Mount Mitchell, Black Dome, Guyot's Peak, Sandoz Knob and Gibbe's Peak, including Smoky Bald and others, form the divide between the Tennessee and Catawba River basins. That, for the present, will be quite sufficient for the topography of the country. As you are no doubt aware, most of the rocks through this region are highly crystalline, but whether of paleozoic or azoic age, is not certain," concluded the Professor.
