upward into the overhanging vegetation on the south side 

 for a few inches there is evidence that after leaving the 

 hard Encrinal bed below, the fault again lowers its dip in 

 passing into the shale above. This is a very unusual 

 exposure as the shale in other observed cases has been cut 

 from under the hard limestone layer and all trace of 

 faulting obliterated.

Fig. 6. — Outcrop of Encrinal layer at the beginning of the high dip just 

 south of Portland Pt., east shore of Cayuga Lake. 



Just opposite Crowbar and % mile south of Portland Pt. 

 the Encrinal appears emerging from the lake with a dip 

 rather steeper than usual. This 5° dip to the south cor- 

 responds with the increased dip of the Tully above while 

 approaching the nearby crest of the anticline at Portland 

 Pt., r i mile north (fig. 6). In it one fault was seen with 

 a dip of 30 z north and striations trending about N 8° E. 

 The iDosition was such as to make an accurate reading of 

 the striated columnar structure impossible. 



On the north limb of the anticline about one mile north 

 of its crest and just north of the bridge over Salmon Cr. 

 near its mouth at Myers, the Encrinal appears in the west 

 bank some feet above the village street with a dip of 1° X. 

 Joints and what appear to be faults occur, but the cliff is 

 too steep to make this part of the bed accessible. Around 

 the second turn up stream it again appears in the other
