 there is little about the Indian's land to suggest its owner-

 way that other farmers do. 



The rocks to be seen near Hagersville are chiefly of 

 Devonian age, although the Silurian-Devonian contact 

 comes to the surface but a short distance to the north 

 and east. A notable feature of the Devonian outcrops 

 is their terrace-like occurrence. These are perhaps rem- 

 nants of old rock terraces connected with the buried 

 pre-glacial valleys, the upper portions of which have been 

 but partially obliterated by drift deposits. The out- 

 cropping formations of this immediate vicinity may be 

 grouped together in the following classification; (9.)

SALINA BEDS. 



The beds, of Salina age, lying immediately below the 

 Devonian of this region are probably the Bertie waterlime. 

 At some places there may be remnants of the Cobleskill, 

 but this is an uncertain matter, as the fossils so far obtained 

 are not conclusive. The Salina beds consisL of drab 

 (weathering buff to yellowish brown) to bluish compact 

 dolomites passing into shales and gypsum-bearing deposits 

 below. At some places, these Silurian deposits include 

 thin streaks of sand, while at the top, the coarse sand from 

 the Oriskany has penetrated the cracks and crevices 

 in all directions, there consolidating into thin seams of 

 sandstone. The Silurian-Devonian contact is uneven 

 and the rocks underneath often show the effects of pre- 

 Devonian weathering. 



ORISKANY SANDSTONE. 



The Devonian often begins with a basal conglomerate 



composed of sub-angular and rounded pebbles of the 



Silurian dolomites mingled with sand, the whole cemented 



into a solid mass. The thickness of this conglomerate
