slates and schists, "which of course must have been com- 

 ming-led with the sediments at the time these rocks were 

 deposited." "" ''' '" '"' "The g-old exists mostly in the 

 western belt of g'ranite in the veins belong-ing* to the horn- 

 blende and g'neiss of the Blue Ridge."' 



Furthermore he claimed to have discovered in his Low- 

 er Taconic sandstones and cherty beds at Troy and Zion 

 (1^ miles southwest of Troy) in Montgomery county, sev- 

 eral species of fossils.' He described these as siliceous 

 corals of a lenticular form, from the size of a pea to two 

 inches in diameter. Two varieties are distinguished and 

 named by him: Paleotrochis (old messenger) major and, 

 Paleotrochis minor. The following descriptive section, 

 in the ascending order of the rocks and beds, in which 

 these supposed fossils were found, is given: 



" (1) Talcose slates, passing into siliceous slates, and 

 which are often obscnrely brecciated. Thickness unde- 

 termined. 



"(2) Brecciated conglomerates, sometimes porphyrized. 



"(3j Slaty breccia, associated with hornstone. 



(4) Granular quartz, sometimes vitreous and filled with 

 fossils and siliceous concretions of the size of almonds; 

 two to three hundred feet thick. 



"(5) Slaty quartzite with very few fossils; about fifty 

 feet thick. 



"(6) Slate without fossils; forty feet thick. 



"(7) White quartz, more or less vitrified, filled with 

 fossils and concretions; seven to eight hundred feet thick. 



"(8) Jointed granular quartz, with only a few fossils. 



"(9) Vitrified quartz without fossils, and thickness very 

 great, but not determined, 



"The fossils also occur in the variety of quartz or 

 quartzite known as burrhstone, and which is often por- 

 phyrized."
