PERRY COUNTY 



Chapter I. 



Physical Geography of the county. 



Perry county is bounded on the east by the Susquehanna 

 river, from five miles above Liverpool down to the gap in 

 the Blue mountain,* four miles above Harrisburg, a distance 

 of 21 miles as the crow flies, and of 29 miles along the wind- 

 ings of the river bank. 



The southern line, adjoining Cumberland county, follows 

 the crest of the Blue mountain westward for a length of 53 

 miles. From corner to corner, if measured on a straight 

 line S. 10° W., the distance is 38^ miles. 



For the entire distance the mountain is unbroken by a 

 single gap deep enough to pass a stream. With the excep- 

 tion of two or three slight notches or air-gaps, the crest 

 maintains a uniform height of about 1000 feet above the 

 Cumberland valley to the south. But the course of the 

 mountain (and therefore of the county line upon the map) 

 is by no means a straight linp. For the first 22 miles from 

 the river it is nearly straight, due westward. Then it 

 curves back northward to Welsh hill and makes a loop 

 (called by the people of the neighborhood Green valley). 

 Coming out again as far as before, to Pilot knob, it makes 

 a second and deeper loop called Kennedy valley. Hence 

 its course is nearly straight (S. 30° W.) for 16 miles, to the 

 Franklin county line corner. 



* Known to the settlers on the lower Susquehanna as the First mountain, 

 further west as the North mountain, and further east, in Schuylkill, Lehigh, 

 an<l Northampton counties as the Kittatinny mountain, which name was 

 adopted by Prof. Rogers in his final report of 1353.
