i didn’t realize Virginia is close to the mississippi river.
Within walking distance.
By the time Jenkins reached the Mississippi he was no longer a vegetarian. A poor mountain man in Virginia, who offered Jenkins a lamb chop, had made him feel foolish about his no-meat diet.
I guess it should have said "A poor mountain man way back in Virginia," in case someone saw it as placing the two together, or "By the time Jenkins reached the Carolina's he was no longer a vegetarian," if in fact he had finally concluded he was done with it. But maybe we need not be so fault-finding.
