crossing Jack’s mountain and the valleys of Penns and Middle creeks. The south line of Snyder is largely a common one with Juniata, running along the west branch of Mahantango creek for about 10 miles, and then a straight line for 10 miles across the Shade mountain.
Jack’s mountain forms a common divide between the two counties for 16 miles west of Centerville and Penns creek, and a county road for an equal distance to Sunbury, so that the Union-Snyder line is about 32 miles in length. The two counties together form a roughly trapezoid shape, with its long base along the river for 38 miles and its shorter parallel line along Mifflin county only 9 miles long.
Straight lines drawn from either end of this shorter line to the extremities of the river line would be about 31 miles on the north or Centre county side and 22 miles on the south or Juniata county side.
Mifflin and Juniata Counties.
Mifflin and Juniata counties together form a block of somewhat larger area than Union and Snyder, and lie immediately west of these two counties. Their eastern boundary line is a common one with the western line of the two smaller counties,
The northern or Centre-Huntingdon county line is an irregular one extending west along the different spurs of the Seven mountains from the gum-tree corner in Penns valley to a buttonwood on the northeast side of the Juniata river, 160 rods below Drake’s old ferry house, an air line distance of about 40 miles, but 48 miles long by measurement along the different mountain offsets. Nine miles of the west end of the line is along the crest of Jack’s mountain, after which it crosses the Kishacoquillas valley in the vicinity of Allenville to Stone mountain, keeping that crest to the Centre county corner.
The western boundary of these two counties is formed by the Juniata river to a pine at the neck of the big bend near the mouth of Sugar valley; thence east for about 2½ miles to the summit of Black Log mountain, a common corner of Mifflin, Juniata and Huntingdon. From here the
