Federal Harbor On the south side of Federal Harbor near the west end, along the shore on both sides of the outlet of Mr. Dickey's lagoon in northern G.V.I.A and just over the lake into G.V.I.5 a lens seems of gray sand tuff, fine grained & chervely last well obliterated, immediately the Silvers Cove glassies. The strikes along the shore from N.25-27° W. and dip 35-42° N.E. The tuffs are very fine siliceous containing many small shells of siliceous remains. Specimens of Eucyathina decua is very common. the remains of large Porifera sp, Lymella cunabula occur as a trace of 664 "Opisthobranch tuffs" of Silvers Cove & forming tube. The fauna in G.V.I.5 A and includes Camarotoechia abundant Gonorettes derjysi, common Cyclocoma aluandant Actinoptercella rare Palmappeila rare Pyrophisonia rare Naryschonia rare Terraculites rare Crinoid ?? common The specimens of the brachiopods distributed with the Camalitocheica gastropods which seem to occur in Silvers Cove, interestingly enough at a depth a few yards below of Mr. Dickey's where the Peglet's tuffs, are and by a very dark lens 25 ft. thick which appears to be a stratigraphic on a large galbino near the galbino which parallels the shore on a little point west of the W. end. 6/41.5 Just to the east part of this galbinos gneiss in the S.E corner of the SW quarter of G.V.I.5 occurs in the west a couple of yards of slightly bluish tuffs overlain by gray bluish-gray olivite beds, N.12° W and dipping 35° N.E.. The strata here occur several feet thick & very well developed. the fauna is ? ? (gray water) with small shells & calcareous mass & dark forming the 60 foot sill W of S of the latter F in Federal Harbor. Intercalated in the mass of galbino ruff 36 feet long beds sandy shales striking N.25°W and dipping w.s.e. These occur on the west side of this point S.W. of the 800 F in Federal Harbor, and contain (G.V.I.516) Orbiculidae ? camarotoechia common Palmappeila (Eucyathina sp.) abundant Actinoptercella uncommon Cypicardium platyphylla one example Pyrophisonia rare Cyclonoma Black Head 23 the base of Black Head on the west side seems coarse gray bedded tuffs striking N.35° W and dipping N.70° S.E. The top they become fassation and grade up into effect of white thick gray pulverized slates which lie in turn northern by a couple of feet of tuffifer, these places the slates. The loose lichen covered tuffs immediately underlying contain & red faunas with gings 6V25 Camarotoechia (Eup) abundant Gonorettes derjysi common Palmappeila rare Actinoptercella rare Cyclocoma (P. Siliceous core) abundant. Pyrophisonia rare Cylonea common Balanusites magnoval Actinoptercella Just beneath the galbino the strike is N.47° W and dip 45° N.E. North of the forest occurs on the lower side of Black Head the tuffs disappear some striking W. 30° W. and dipping 50° NE. They are dark gray & red, and under 2125° and much layered & grey the latter extremely amygdaloidal or pyroclastic. The beds and coarse plates of G.V.I.A (N.3 P) is exposed in old road side of Federal Hare Peglet's rock struck but I believe core copy of these shots as probably probable the thick 2
