to the overturning of the beds. A second longitudinal or strike 

 fault (no. 12) begins in the Manlius on the northeast and a little 

 later passes into the Coeymans [section 10] ending finally in a 

 small diagonal fault. Thus once more eastward dipping beds 

 are brought in contact with the steeply overturned strata, par- 

 tially repeating the Manlius in the upper, and the Coeymans in 

 the lower section (nos. 9 and 10). 



A little farther southward, another triangular fault block 

 occurs, bounded by faults 11, 13 and 14. The probable struc- 

 ture of this block is shown in section 10. On the east the over- 

 turned Manlius, Coeymans, New Scotland and Becraft are visi- 

 ble, all dipping very steeply to the southeast, some beds being 

 almost or quite vertical. A low ridge of Becraft with the strata 

 standing vertically, is succeeded westward by a flat valley [see 

 section 11] in which no strata are exposed. This valley is 

 bounded on the west by fault 10, beyond which is another ridge, 

 on the summit of which the Becraft is again seen dipping 40° 

 northwestward. No exposures are shown at the base of the 

 ridge at this point, but it is almost certain that the New Scot- 

 land lies at its base and that it is merely a southward con- 

 tinuation of the same structural ridge found just northward, 

 where the New Scotland is shown. The westward dipping 

 strata are bounded on the east by fault 10, which has here 

 turned more to the west. What strata occur between the fault 

 and the low ridge of Becraft have not been ascertained, as no 

 satisfactory exposures were noticed. Some rock masses which 

 appeared to be in place, were finely crystalline, shattered and 

 veined limestones, which may represent either the Coeymans 

 or Port Ewen. No fossils were obtained, but from the character 

 of the strata a little farther south [section 14], it appears most 

 natural that the valley is occupied by a closed synclinal fold of 

 Port Ewen, with possibly some Oriskany in the axis of the fold 

 (which would account for the valley). The Becraft probably 

 comes up again on the other side of the syncline, next to the 

 fault. Fault 14 is followed by an old wood road, which leads 

 down to the main road east of the mountain. South of this 

 fault the Manlius forms the greater part of the surface. It
