SCIENTIFIC SURVEY. 9-tj 



skirts the shore of the north part of the island between Hull' 



s 



Cove and Saulsbury Cove. A dike of trap containing veins of lime- 

 stone appears at Hull's Cove. Probably this rock does not extend 

 inland further than a line connecting the two coves. The dip of 

 the strata could not be satisfactorily determined. 



The first salient point in the section is Green mountain, 1,533 

 feet high by our Barometer. The rock at the summit is protogine, 

 having a talcose mineral substituted for the mica of granite. The 

 color is red. No doubt a great portion of the so called granite of 

 the whole island is protogine. Large plates of the protogine at the 

 summit dip 60° N. W., while near Eagle pond they are perpendicu- 

 lar. A few dikes of trap are found on the mountain also. The view 

 from Green mountain is delightful. No other peak of the same 

 height can be found on the Atlantic coast of the United States, from 

 Lubec to the Rio Grande, nor from any eminence on the coast, can 

 so fine a view be obtained. We were never charmed by any view 

 so much as by this. The boundless ocean upon the one side contrast- 

 ed with high mountains upon the other, and along the shore line 

 numerous islands appearing like gems set in liquid pearl, form the 

 most prominent features in the scene. White sails dotted over 

 the water glide slowly along. We know not what view can be 

 finer than this, where the two grandest objects in nature, high 

 mountains and a limitless ocean occupy'' the horizon. The emo- 

 tions awakened by this scene cannot be expressed, but the scenery 

 remains in the memory, the never dying reminescence of a beautiful 

 portrait placed in nature's gallery by the Master Painter. The name 

 of Eden is truly appropriate to this beautiful place. 



Following the line of the section we found quite a high mountain of 

 granite in the north part of Eden. At Thomas and Iladley 's Mill, on 

 the north shore at the mouth of a stream, there is a band of granite. 

 The spur of the land running out to the Toll-gate is composed of a 

 variety of gneiss, appearing rather talcose, yet abounding in feld- 

 spar. The first dip is 35° S. 20° E., or beneath the granite rocks. 

 At the first island on the bridge road the dip is 30° S. E. At the 

 Toll House is a narrow slaty ledge, perhaps the first of the succeed- 

 ing formation, dipping 45° S. 12° E. Upon Uncle Israel's point, a 

 mile east of the Toll House, the rock is very distinct gneiss, dipping 

 37° southerly, and is intersected by four trap dikes, two of which 

 are only one foot wide, while the third, a mass of columns, is three 

 feet wide, and the fourth, a crystalline trap, is eighteen feet wide.
