Rh needed. The better stone occurs further south in the top of the quarry, but none of it seems particularly attractive.

The Oriskany sandstone No. VII, lying south of the limestone belt, is composed of shale and chert, which has been so largely eroded by the action of Penns creek as to make its location uncertain.

TheMifflinburg ridge in the northern portion of the township, has already been referred to as containing a good series of limestone beds. About a mile west of Mifflinburg there are three small quarries opened about 250 yards south of the pike, all in the same portion of the Lower Helderberg formation, as exposed in the large town quarries on the West Buffalo line. The dip is about s. 15° E. 10°-20°,

Royers quarry, with two kilns, is the first operation; Kleckner’s, with one kiln, the second; and Youtz’s, with one kiln, the third. The first two are practically continuous, and expose about about 30′ of rock, including the soft blue-gray stone, for a distance of about 100′ along the outcrop. The Youtz quarry is about 100 yards west, and while it was not thoroughly developed, presented a face of excellent stone. None of these quarries were being operated when visited and are probably only developed for private farm purposes.

J. Strickler had just started a small quarry along the north flank of the ridge, about one mile west of the Youtz quarry; but comparatively little stone had been quarried here.

Immediately south of Mifflinburg and somewhat higher in the ridge than the town quarries:—

Anspach & Cotelius’ quarry is opened close to the synclinal in limestone, dipping about 5° S. E., the reverse dip showing a little higher on the ridge. The stone exposed here is not burned at all and occurs geologically above the good fat-lime beds of the Lewistown formation, and is largely developed for building and paving purposes in Mifflinburg. It has a blue color and is exceedingly hard, breaking out in small or large blocks as required, and apparently an excellent stone for the purpose for which it is required. There is about 20′ of rock exposed in the quarry
