The Little Compton Shore. 



As a check upon the correctness of the preceding observations 

 the shore of Little Compton was visited. Jackson's map merely 

 indicates a strip of " Grau Wacke," beginning near Stone Bridge 

 in Tiverton and extending along the shore nearly to Brown's Pt. 

 in Little Compton and separated from the adjacent granite by a 

 strip of " Metamorphic Rocks." 



The following observations were made : At 58, south of Fog- 

 land Pt., grits dip 25°-30° E.SE. and strike about K 30 E., are 

 overlaid at 59 by quartzite conglomerate which forms High Hill 

 Pt., about 35' high, and continues to 60. These are evidently 

 the same rocks as between 20 and Black Pt. cut by the " River." 

 The next outcrop, going south, is at 61 where gray argillaceous 

 schists and shales dip 25°-30° E.SE. and strike K 30 E. At 62 

 carbonaceous and argillaceous schists and shales with same dip 

 and strike. The carbonaceous layers exposed contain traces 

 of fossil plants. Quartz veins with traces of graphite traverse 

 them. On the beach fragments of ferruginous schist like that at 

 Wood's Castle, with which these schists strike. At 63 fine, soft, 

 slaty conglomerate, schists and grits dip 30°-35° E.SE. ; a little 

 beyond 20° S.SE., with quartz veins 1' thick near by. At 64 the 

 same rocks dip 30°-35° S.SE. The next outcrop is at Brown's 

 Pt. where a light green chloritic schist with crystals of magne- 

 tite stands out of the water striking roughly NE. by E. Back of 

 this Point, at 65, a great mass of schist is exposed, fragments of 

 which have afforded numerous cyclopaean walls thereabout ; 

 strike the same as at the Point, dip at high angle. These schists 

 are of two kinds : a chloritic, argillaceous schist with lenticular 

 passages of calcite or dolomite, a dark gray argillaceous and mica- 

 ceous schist with like passages. Both are finely stratified and 

 plicated. At 66 the highway crosses the same beds. The next 

 outcrop is at 67, just north of Church's Pt., where schists of a 

 somewhat similar character appear, dipping 35°-40° SE. by E., 

 and striking N. 30 E. The green layers overlie the gray ones. 

 These rocks continue to 68. The next outcrop is at 69 near 

 Church's Cove where a light colored rock composed of fine 

 plicated layers of mica schist and quartz strikes about N. 30 E. 

 A few rods further south chloritic schists exactly like those of
