220 T. N. Dale—Geology of Rhode Island. 
In order to rectify these contradictions and, if possible, de- 
termine the structural and chronological relations of these beds: 
the following observations were taken. 
Easton's Beach, the Cliffs, Newport City— At 1 (see map), at. 
east end Easton’s Beach, alternating layers of conglomerate 
and dark gray argillyte dip 5°-10°-20° E.SH.* The nearest: 
outcrop westward is at Bliss’ Cave, 2, where similar rocks dip 
30° W.N.W. At 3, west end of beach, alternating argillaceous- 
and carbonaceous schists, grits and quartzyte conglomerates 
measure over 100 feet, dipping 45° W. At 4, corner of Gibbs 
avenue and Catherine street, 20 feet’ below the surface, pale 
greenish argillaceous schists with sparsely disseminated, minute, 
erruginous nodules dip rou . As “The Cliffs” trend 
about N. 10° E., nearly with the strike, and as they advance 
and recede alternately the series is not easily made out.t The 
layers of conglomerate sometimes run out or fork. any 
veins of milky quartz, large and small, traverse the rocks, 
sometimes starting abruptly from the junction of the conglom- 
erate and slate and tapering upwards through the former, gen 
erally vertically and from K.-W. A little N. of 6 the dip is 90 
‘and slickensides occur parallel with strata. At 6 the dips 
60° W. and slickensides are horizontal. At 5 and 6, among 
the shingle, quartzyte pebbles (possibly not from the outerop- 
ping conglomerate) containing Zingule with plumbaginous 
shells. The outjutting rocks opposite Narraganset avenue ane 
the like-shaped mass south are due to the converse of the 
process which formed the chasm “ Purgatory,” the rock be 
tween two H.-W. fissures being left. while that on either side 
has been eroded. At 7, opposite Miss Wolfe’s, about 20 feet 
of schist overlaid by about the same thickness of conglomerate — 
dip W. At Mr. Lorillard’s Breakwater, 8, the easternmost 
layers, grits and conglomerate, dip 65° E.S.E. ; then about 20 
feet of grits and dark gray schists dip 45°-50° W.N. W. crossee 
by slickensides, dipping about 75° W.N.W. Thence to Ochre 
Point, pale greenish, argillaceous schists with occasional layers — 
of conglomerate, dip 85°-45° E.S.E., measuring perhaps 4" — 
feet. The outlying line of rocks at Ochre Point indicates the : 
direction of the strike and consists of the lowest conglomerate : 
of the Ochre Point series, In passing westward the dip — : 
denly changes to 25°-30° S.S. W., the rocks being pale greens 
possibly hydro-micaceous schists with minute crystals of magy 
netite, in places reddish yellow, ochraceous schists, and trave d a 
by several quartz veins. At 9, this bed seems to be unde 
by conglomerate and grit, dipping first 25° H.S.E. then 25 -°©
