TAGGAETS FEERY TO SMITHS COVE. 293 



dips more steeply, 55^ E Overlying this, conglomerate with medium- 

 sized pebbles dips 70° to 80*^ E. Then comes a comparatively thin layer 

 of coaly sandstone and a conglomerate with pebbles of medium size, both 

 dipping 80° E. Then a considerable thickness of dark-gray, more car- 

 bonaceous shaly rock is exposed, and an equally thick bed, perhaps 40 

 feet, of rather coarse conglomerate, dipping 80° E. Overlying this occurs 

 carbonaceous sandstone, with coarse conglomerate farther east; dip vertical 

 or 80° E. along the promontory which they form at the north end of the 

 cove; but farther north, along the shore, the same beds dip 80° W. This 

 same dip, varying to vertical, is shown for some distance northward, until 

 the beds gradually incline more and more eastward, as already noted. 

 South of the cove the dip is 75° E. It is evident that the same beds of 

 coarse conglomerate, with the underlying sandstone series, have been 

 folded in such a way as to dip more steeply in coming southward along the 

 strike toward Taggarts Ferry; at the ferry there is a slight overturn, the 

 dip being 80° to 70° W., and immediately south of the ferry the dip returns 

 to 75° E. with sufficient suddenness to denote a stronger flexure at the 

 southern end of the cove 



The Sakonnet sandstones in the cove and westward correspond strati- 

 graphically to the sandstone north of Black Point. 



From the cove southward to Woods Castle we pass from lower to 

 higher rocks in the conglomerate series. The dip is steeply eastward — 

 usually about 70° E. At Woods Castle a bed of coaly shale occurs, over- 

 lying that part of the conglomerate series forming the shore. It contains 

 abundant fern remains. Eastward, after an interval of perhaps 30 feet, 

 probably also underlain by shaly rock, the great isolated mass forming the 

 conspicuous feature of this coast line is exposed. It is composed, at least 

 on the west side, chiefly of coarse sandstone. The stratigraphy was not 

 carefully followed, but the coaly shale bed seems to correspond to a more 

 sandy, coaly shale exposed about a quarter of a mile north of the cove at 

 Taggarts Ferry, and the sandstone overlying it replaces a coarse conglom- 

 erate. In other words, the fern locality at Woods Castle occurs well within 

 the coarse conglomerate series, and not overlying the same. Southward, 

 toward Smiths Cove, the dip is less steep, becoming, near the southern end, 

 as low as 50° or even 45° E.
