EARLY DEVONIC HISTORY OF NEW YORK AND EASTERN NORTH AMERICA 59 



3459 Black Point ; strike about same as foregoing. Some layers 

 of the rock are full of Leptocoelia and can be traced for considerable 

 distance into the clearing. 



Brassua lake, Moose river 



At the south end of lake are altered and volcanic rocks' which extend 

 through to Moosehead lake along what is called the Blue ridge and on the 

 east side of Mount Kineo. On the west side of Brassua lake from Misery 

 stream to the outlet, shaly sandstone outcrops at many places but no fossils 

 have been observed. 



3461 On the west shore above Moose river are loose blocks with some 



3462 fossils and on the east shore opposite is a fine grained sandstone 

 having a strike e. ne. and dip 80 n. nw., carrying Rhipi- 



3463 domella musculosa. Just south of this point, sandstone 

 blocks apparently in situ carry Rensselaeria in abundance and 

 the rocks extending thence for a mile or more to the southeast 

 carry the same fossils. 



3464 Soccatean or Saccadean point : just to the north is dark shaly 

 sandstone. Strike e. 15 n., dip 85 s. 10 e. These fossils were found : 



Cypricardella parmula Cardiomorpha simplex 



Palaeosolen simplex Spirifer 



Palaeosolen Rensselaeria steward 



3465 Continuing northward along the shore for a quarter of a mile is 

 quartzite overlain by a sandy shale showing decided change in 

 attitude, striking ne. with a dip of 75 se. The continuation 



3466 of this stretch of rocks emphasizes the variability of dip and the 

 extreme folding and cleaving of the strata and also brings to 



3467 light differences in the sediments which vary from a sandy shale 

 often with many crushed and distorted fossils to compact 



3468 sandstones of much thickness. 



Just below the outlet of Moose brook is a prominent point of heavy 

 sandstone with strata standing vertical. Here and on Moose Brook island 

 adjoining fossils are common.
