KINGSTOWN SERIES AT THE BONNET, 333 



in any fnlly exposed section, but suffered more from weathering and now 

 lie hidden under tlie more recent glacial and sand-plain deposits, leaving 

 the coarser sandstones to form almost the only exposures rising above the 

 sand-plain level. For this reason it is not safe to make any distinction 

 between a more shaly and a less shaly series on the western shore of tlie 

 bay. On the contrary, it is very likely that shales also form an important 

 element of the series northward and westward, away from the shore line, 

 but that, on account of their more ready erosion, they do not frequently 

 appear above the soil. 



On account of the far greater abundance of sandstones among the 

 rocks of this western area, so typically developed in South and North 

 Kingstown, than in the Aquidneck shales farther east, the name Kingstown 

 sandstones is suggested for this western complex of strata, as being of value 

 in designating them when it is desirable to distinguish the two formations 

 where they are typically developed. The Kingstown sandstones underlie 

 the Aquidneck shales. 



Section from the Bonnet to Boston Neck. At tllO BonnCt the KiugStOWU SerfeS dipS 



about 60^ E., giving an exposed thickness of about 700 feet, with a possible 

 thickness of about 1,350 feet, if we inchxde the area as far west as Wesquage 

 Pond, which area, although without exposures, may be presumed to be under- 

 lain by similar rocks. Judging by the strikes along the shore, the lowest 

 part of this section, consisting of the strata supposed to underlie the eastern 

 edge of Wesquage Pond, can lie only a short distance above the most 

 eastern exposures on Boston Neck and at the South Ferry. The most eastern 

 exposures on Boston Neck dip nearly vertically; southeast of Watsons 

 Pier the rocks dip 60° E.; west of the pier they dip 45"^ E.; three-quarters 

 of a mile northward, 15"^ E.; these exposures, with the intermediate terri- 

 tory, add approximately 800 feet to the section already given, and make 

 a total of 2,150 feet for the thickness of the Carboniferous section from the 

 Bonnet southward, assuming that no folding has taken place. 



Section from the Bonnet to Hazzard's quarry and Indian Corner. Thc Strata CXpOSCd aloUg 



the shore of Boston Neck are probably repeated north of South Ferry, 

 but the dips here are low, between 20^ and 40*^ E., at times nearly hori- 

 zontal, so that until much more accurate field work is done the strata north 

 and south of the Bonnet can not be strictly compared with one another. 

 The Bonnet section as far west as Wesquage Pond was estimated at 1,350
