12 The Stone Quarry. 



ette valley we find twenty or more well worked 

 stone quarries along both lines of foothills 

 from Eugene to Portland. Now, if we col- 

 lect from all these localities their characteristic 

 fossils and spread them out before us, and 

 then call upon our quarryman to examine 

 them without any help from science, he will 

 at once separate them into three groups. 

 Jackson and Josephine county fossils, as well 

 as the rocks that contain them, having a fam- 

 ily likeness, he will place by themselves in 

 one group. He will as promptly select Doug- 

 las and Coos county rock and fossils, and 

 make of these a second group. He will with 

 equal readiness place all those from the Wil- 

 lamette valley in another, a third group. If 

 you ask him for his reasons he will answer, 

 "O, they look different;" and so they do. 



If now we doubt the soundness of our 

 quarryman's opinion and call in a student of 

 science, he will at once verify the classifica- 

 tion of the quarryman and declare that Nature 

 herself pronounces its correctness. Plainly 

 this will at once suggest to our quarryman
