110 F³. west on the south side of the next road crossing the ridge and is close to the Limestone township road.

This is a small township lying south of West Buffalo and Buffalo townships, and extending south to the Snyder county line, having Penns creek for its southern border line from a point about 1½ miles east of New Berlin to the end of Jack’s mountain beyond Centreville, with an additional 2 miles along that mountain crest.

Its western line is a straight north and south one in common with Lewis township, about 3 miles in length, and its eastern township line, dividing it from Buffalo township, and Union township, has a double irregular L-shaped offset for 2 miles along Limestone Ridge and about the same distance along Shamokin mountain. It may be roughly computed at about 7 miles east and west and 3 miles north and south, its total area approximating 24 square miles.

Penns creek, following the northern base of Jack’s mountain for about 2 miles and thence eastward for over 5 miles along the Snyder county line, comprises, with its numerous small branches, the chief of which is Sweitzer run, the entire drainage outlet for the township, and as it cuts entirely through the Jack’s mountain spur, double outcrops of the Clinton, Salina and Lower Helderberg measures are exposed along the southern portion of the township on both sides of the Jack’s mountain anticlinal.

New Berlin, formerly the county seat, situated upon the north bank of Penns creek, is the principal village of the township, while Battletown and White Springs are the names of two smaller villages located respectively on Sweitzer run, about 2 miles northwest of Penns creek, and upon a small tributary stream in the southwestern corner of the township.

The geological rock section extends from the red Medina rocks No. IVb of Jack’s and Shamokin mountains, up to the Oriskany sandstone, occurring on the summits of the Mifflinburg ridge and in a narrow outcrop along the north
