the most part of a stratified metamorphic character. The whole 

 peninsula is of sedimentary origin, and in some portions, aqueous 

 deposits have alone been concerned in its formation. Although 

 occupying an extensive area, little variety is apparent, the group 

 consisting principally of compact felspathic rocks, with some chloritic 

 slates and numerous beds of interstratified greenstone or diorite. 



u Three parallel bands, differing slightly in character, and running 

 the entire length of the peninsula, may be distinguished. 



" The first, forming the southern side of the peninsula, and skirting 

 the north shore of the Kennebeckasis in a series of very bold and 

 remarkably picturesque cliffs, is largely schistose, and extends with 

 an almost unbroken front from the Milkish to Hampton Ferry. Near 

 the latter place and opposite Darling's Island, the group is represented 

 by the following rocks : — 



u Gray gneiss (?) or altered micaceous sandstone, with small crystals 

 of red felspar.— Str. N. 60° E. 



" Greenstone or diorite. 



11 Porphyritic felspathic schist of a pink colour, weathering white. 



" Gray felspathic quartzite, injected with quartz veins. 



" Grayish white altered slate. 



" The whole series is nearly vertical, and no satisfactory dip 

 could be ascertained. My impression is that the tendency is to 

 the north. 



" In the neighbourhood of Clifton, rocks of the same band contain 

 large masses of chlorite and epidote, with veins of specular iron. 



" The second band of rocks alluded to, although passing insensibly 

 into the last, differs from it chiefly in the much greater abundance of 

 altered sandstones and bedded greenstones, with a comparative in- 

 frequency of slaty beds. The greenstones or diorites are interstratified 

 with compact felspathic rocks, varying from white to pale pink, the 

 latter at times associated with and passing into fine-grained syenite 

 and syenitic gneiss. Slates are comparatively rare, and when oc- 

 curring, are sometimes chloritic and sometimes micaceous, being also, 

 as a rule, much twisted. Like the members of the first division, these 

 rocks also contain chlorite and epidote. The group may be readily 

 seen in the village of Kingston, or along the Land's End at the south- 

 west extremity of the peninsula. 



" The third band, into which the last insensibly passes by the 

 absence of its bedded diorites, occupies principally the northern side 

 of the peninsula, where it is represented by a comparatively uniform 

 series of clay and chloritic slates. Though not so numerous as in the 

 centre and south of the district, trap beds are present, and at times
