“ The Lehigh River flows out of the Alleghenies through a deep and tortuous valley which rends the mountain ridges until it strikes against the South Mountain range, here called the Durham Hills, and then turns northeast along its base to the Delaware. At this bend the Saucon Creek comes in from the south and the Monocacy Creek from the north, and here, twelve miles from Easton, is Bethlehem. This manufacturing town of twenty thousand population is one of the noted places of the Lehigh Valley. ”
