SCIENTIFIC SURVEY. 249 



Prison quarry in Thomaston with the strata inclined 80° S. E. If 

 the rock extended further, the valley of the St. George river would 

 be the place to find it. Northeasterly from the prison the lime- 

 stone extends into Miller's and the Beechwoods quarries. At 

 Miller's the rock is whiter than is common in this vicinity, dipping 

 from 65°-70° N. 40° W. Further on the dip is ten degrees greater. 

 It now begins to curve to the east. At the south end of the 

 Beechwoods it runs N. 80° E.; southeast from here it runs N. 15° 

 E., and finally at the Fulling Mill quarry, not far from the east end 

 of Thomaston street it dips 40° N. Then it bends back again to 

 its former course, and passes into the Meadows quarries, unless 

 there is a break, which is improbable. 



At the Fulling Mill quarry the rock is unusually dark. At the 

 mill itself it is yet darker and makes a good marble, slabs of which 

 have been sawed out in times past, some of which remain here 

 showing their excellent character. Below the Fulling Mill quarry 

 on Mill river is an old quarry of white marbleof excellent quality, 

 dipping 20° N. 30° W. This is in Mr. Jacob's pasture. Above 

 the marble is a bed of schist thirty feet wide in the limestone, with 

 a greater dip, viz., 60°. In returning to the village from the mar- 

 ble quarry one passes by several exposures of limestone. At a 

 quarry where a siliceous limestone was being blasted for paving 

 and building material the dip is 60° JST. W., and again 50° N. W. 

 The nearest exposure of the limestone to the mass of schist at the 

 east end of Main street, is near Elm street, and the strata are 

 inclined 25° N. 30° W. These details are of practical interest, aid- 

 ing in the development of the rock suitable for the manufacture of 

 quicklime. 



Both a north-westerly and a south-easterly dip may be found in 

 the different openings of the Meadows quarries. Along the line 

 of the section in Fig. 38, we found the following positions. At the 

 south-east side of the limestone, the dip is 15° N. W. At the 

 calcite locality the dip is 80° S. E. Between this opening and the 

 one on the west side of the north and south road where a variety 

 of white talc occurs, the dip is north-westerly, but variable, from 

 20°-80°. Several slips are noticeable, and we have attempted to 

 give an idea of the irregular dip and the slips in our section. On 

 the west side of the road the strata dip 15° S. E., becoming steeper 

 according to the depth in the quarry. But no particular dip is 

 constant through all these openings. The total length of this
