line. This set of exposures indicates a strike of N. 15^ E. East of tlie 

 last exposiu^e is coarse sandstone. Toward the northwest and north extend 

 several ridges of sandstone and conglomerate, the most eastern of which 

 can be followed for a mile, as far as the next east-west road. The strike 

 is N. 15° E., dip always eastward, often as low as 20°. Conglomerate 

 and sandstone also occur north of a house some distance east of the road, a 

 quarter of a mile south of the State boundary line A mile northeast of 

 Kings Rock numerous exposures border the roads eastward and northward. 

 They consist chiefly of sandstone and some conglomerate, dipping eastward, 

 but they also contain greenish shaly layers toward the north end of the 

 series of exposures, where the strike seems to be more nearly east-west and 

 the dip southward. 



A third range of bluish shales forms a ridge bearing N. 15° E., both 

 north and south of the road to Luthers Corner, already mentioned. East- 

 ward from this ridge, three-quarters of a mile northward along the first 

 road on the east side, conglomerate is exposed; strike N.-S., dip 70° E. 

 Greenish shale underlies it on the west. 



The various exposures north of Bristol Neck, just described, seem to 

 indicate that the bluish-green shales underlie the great mass of conglom- 

 erates. These conglomerates are the coarse conglomerates on Aquidneck 

 Island and occur at a considerable distance above the lowest beds of the 

 Carboniferous exposed along the eastern shore line of the basin, from 

 Steep Brook to Tiverton.

The eastern line of outcrops of the coarse conglomerate runs through 

 Swansea village, in a northeasterly direction. Beneath these conglomerates, 

 on the east, occurs a series of shales and sandstones. South of the pond 

 southwest of Swansea village, in the bed of the creek which forms its 

 outlet, and in the field between the creek and the road, there are several 

 exposures, chiefly sandstone, but also some more shaly courses, dark 

 blue in color. Southward rather more than a mile, on the road to South 

 Swansea, an exposure of coaly shale occurs south of the road leading 

 eastward to Fall River. This exposure occurs in a digging on the eastern 

 side of the Neck, near the top of the hill Half a mile farther south, near 

 the base of the hill, toward Lees River, a shaly sandstone or slaty rock
