2 P. REPORT OF PROGRESS. E. W. CLAYPOLE. 



The southwestern boundary line, adjoining Franklin 

 count}*, is a series of nearly right angled jogs. Commencing 

 on the south at the Blue mountain crest, it crosses Henry 

 valley to Little Round Top and Round Top, and Horse 

 valley to the crest of West Tuscarora mountain, the air- 

 line distance from corner to corner being 8J miles. 



The north-western boundary, adjoining Juniata county, 

 would be a nearly straight line (E. X. E.) 45 miles long, were 

 it not lor two small offsets to the northwest, thus : crest 

 of W. Tuscarora mountain (nearly straight, E. N. E.) 10 

 miles ; offset to the northwest across Liberty Valley to the 

 top of Tuscarora mountain, If miles ; along crest of Tusca- 

 rora mountain, (nearly straight, E. N. E.) to the Juniata 

 river, 22^ miles ; offset to the northwest, 1 J miles ; thence 

 nearly straight (E.) 12f miles to the Susquehanna river. 



The shape of Perry county is therefore that of a slightly 

 curved blunt wedge, about 15 miles wide at its eastern base 

 and 8 miles wide at the south-western edge, with an average 

 medial length of 40 miles. 



It is said to contain 539 square miles, or 344,960 acres,* of 

 which at least one fourth may be said to be occupied by 

 ranges of mountains from 600 to 1200 feet high,f covered in 

 large part by forest trees of the second, third, or fourth 

 growth, and separated by arable valleys, mostly narrow and 

 long, and by glens heading up between the ends of the 

 mountains. The larger valleys in the eastern part of the 

 county are sub-divided by low ridges, also much wooded, 

 but mainly cultivated. 



The population of Perry county in 1860, was 22,793 ; in 

 1870, 25,447; in 1880, 27,522. 



Townships. 



There are twenty townships in the county, five of which 

 border on the Susquehanna river, viz: Liverpool, Buffalo, 

 Watts, Pom. and Rye; live occupy the triangular space 

 between the Susquehanna and Juniata livers, viz: Liver-
