Jack's Narrows, 1879
Jack's Narrows in 1879, in an engraving of the gorge where the Juniata breaks through Jacks Mountain.
The rocks are the reason there is a town here at all. They are also, later, the reason there were brickworks: the ganister that drew the refractory companies came off these ridges.
The name is older than any of it, and it is not Captain Jack's. In about the middle of February 1744 an Indian trader called John Armstrong was murdered at the Narrows above Mount Union, along with his two companions James Smith and Woodworth Arnold. It was that killing, Africa's county history says, that "gave name to the narrow gorge through which the Juniata breaks its winding course." Lytle devoted a chapter of his 1876 history to the rival Captain Jack story and headed it "A popular error."
