only temporarily so, and the extensive quarries south and east of the town ail showed good sections of the limestone measures upon 30° 8. E. dips. The limestone industry, however, has evidently deteriorated for some reason at this point, for many of the kilns have been entirely dismantled as if the owners did not contemplate an early resumption. With railroad facilities so near at this point it seems strange that an extensive operation for quarrying and shipping both stone and burned lime is not inaugurated, for there would seem to be no good reason either in the character of the stone or in its location to prevent such an operation being successful.
The Benchof or Tees quarry is the most eastern opening and is worked periodically. It shows some excellent stone, the lower portion 10′ to 20′ thick, consisting of a good blue and gray rock, fine and smooth-grained; 15′ of darker rougher stone, but of good quality and from 10′ to 20′ of thin beds on top, the dip is S. 100° E. 30°.
A section of this quarry from top to bottom amounts to 66 feet, thus:—
| 1, Shaly limestone, in very thin beds, | 10′ |
| 2. Blue limestone, irregular fracture, and weathering rough, | 20' |
| 3. Bluish-gray massive bed, somewhat jointed, | 12′ |
| 4. Blue limestone, smooth grained and of good quality, | 8’ |
| 5. Dark blue limestone in beds 2’ thick, | 6′ |
| 6. Gray shaly limestone in bottom of quarry, | 10′ |
The opening is about 100′ long east and west, and has been a large producer in the past, though idle during the summer of 1888. An excellent quality of lime should be made here.
Some little development has been made in a smaller quarry immediately east, equipped with two kilns and developing largely the upper strata.
Mifflinburg borough owns the next quarry further west, where the same rock section practically is exposed on a dip of only 6° to 10° S. E. This is sometimes known as the Wolf quarry.
The Mench quarry shows a similar dip and is located just west of the road crossing the ridge to Centerville and the Faust or Hearn quarry lies a short distance still further
