At L. P. Tenney's, N. 82° E. 20°. 



The massive character of the rock in some 



of the localities in Newport makes the 



dip of the strata very obscure. 

 Unity. 

 At N. C. Himtoon's, N. 80° E. 10°. 

 At S. Pierce's, N. 82° E. 15°. 

 East of A. C. Sleeper's, S. 38° E. 18°. 



Acivorth. 

 South of Coffin hill, S. 18° E. 15°. 

 At S. McKeen's, S. 53° E. 68°. 

 Forks of road east of school-house No. 10, 



S. 68° E. 15°. 



Leinpster. 

 At J. Carpenter's, S. 53° E. 15°. 

 At T. Pollard's, S. 68° E. 18°. 

 At Wm. Gee's, N. 38° E. 70°. 



Marloiv. 

 At L. S. Rogers's, N. 82° E. 48°. 

 At H. Priest's, S. 48° E. 25°. 

 Fork of road east of A. Mack's, S, 32° E. 



60°. 

 East of village, S. 58° E. 80°. 

 At A. Whittemore's, S. 56° E. 50°. 



Stoddard. 



At C. D. Elliott's, S. 62° E. 88°. 

 Keene and Westmoreland. 



South of reservoir, S. 70° E. 40°. 



The protogene gneiss in the east j^art of 

 Keene seems to have an easterly dip ; 

 but here and in Westmoreland, the 

 dip is very obscure. 

 Swajizey. 



The gneiss of Swanzey appears to be gen- 

 erally vertical, though there seem to 

 be two exceptions, one on Mt. Caesar, 

 and the other at L. Dickenson's. At 

 both places the inclination is 10° or 

 12° north-westerly. 



Winchester. 

 At Naramore's mill the strata are vertical. 

 West slope of Second mountain, S. 82° 



W. 75°- 

 North-west of E. S. Adams', N. 82° E. 80°. 

 West base of Stone mountain, S. 70° E. 



58°. 

 Peaked hill, strata vertical ; strike N. 10°

Ferruginous Schists. 

 These schists are scarcely distinguishable, on the one hand, from 

 the White Mountain schists and gneisses, and, on the other, from the 

 fibrolite schists. So nearly allied are some of these rocks to the White 

 Mountain schists, in many of their lithological characteristics, that 

 they seem to pass, by insensible gradations, into rocks so like those 

 that occur in the White Mountain region, that there seems to be little 

 doubt but that all of the rocks we shall describe under the head of 

 "Ferruginous Schists" belong to the White Mountain series. Neither 

 is there any very marked distinction, save the presence of fibrolite, be- 

 tween these rocks and those we shall describe under the head of "Fibro- 

 lite Schists." In these ferruginous schists the large plates of mica are 

 usually, though not always, wanting. They often contain beds of graph- 

 ite, and are sometimes concretionary. The relations to the porphyritic 

 gneiss show them to be among the oldest of our crystalline schists. The
