198 GEOLOGY OF THE NABRAGAi^SETT BASm. 



anticline which is traceable westward along the valley of Tenmile River 

 in the Providence quadrangle. 



Eastwardly there are no exposures along this strike line until we reach 

 the small quarry of gray sandstones opened alongside the railroad between 

 Britanniaville and the junction of the Attleboro branch railroad. About 

 IJ miles north-noi^theast outcrops occur on the west of Scudding Pond. 

 About 4J miles farther east coal has been reported on the southern boi^der 

 of Gushee Pond, but the stratigraphy of this region is concealed by drift. 



South of this belt, in the latitude of Taunton, the Seekonk beds, over- 

 lying the above, come in with southerly dips and disappear on the west 

 beneath the synclinal axis on which stands Great Meadow Hill. The sti^ata 

 are medium conglomerates, sandstones, and shales. Coal has been found 

 in the uppermost beds underlying the coarse Dighton conglomerates about 

 1| miles northeast of Great Meadow Hill. So far as has been determined, 

 this is the highest occuiTence of coal in the basin. 



Taunton waterworks section. — Eastwardly and at a somewliat lower level, though 

 probably in the horizon of the Seekonk beds, coal was again met with in 

 sinking an artesian well for the waterworks of the city of Taunton. The 

 well penetrated to a depth of 975 feet. The dip is reported to have been 

 about 40° N. The following table gives the thickness of the several strata 

 penetrated. The data were furnished by Mr. George F. Chace\ The 

 measurements are approximate, and are based upon the nature of the 

 materials brought up by the sand pump. The amounts indicate the depth 

 of each bed.
