To the Quartz Peak section we have to add about 1000 feet 
01 the right-gray siliceous limestone as observed on the northeast¬ 
ern slope of the Peak that is found between the top of the Quartz 
r«ak section and the base -of the Siluro-Devonian section to the 
east of it. Not finding any Lower Devonian fossils in the latter 
section we again supposed the beds were Devonian and from the fact 
thau Stromotopora and other slender corals extend down to the great 
light-gray siliceous limestone No.1 it appears best to draw the 
V* 
pint. This will leave not far from 1000 to 1500 feet in the 
Jpper Silurian.
