GEOLOGY 



BY 



WILLIAM B. SCOTT 



BLAIR PROFESSOR OF GEOLOGY AND PALAEONTOLOGY 



IN PRINCETON UNIVERSITY 



There rolls the deep where grew the tree. 



O earth what changes hast thou seen ! 



There where the long street roars, hath been 

 The stillness of the central sea. 



The hills are shadows, and they flow 

 From form to form and nothing stands ; 

 They melt like mists, the solid lands, 



Like clouds they shape themselves and go." 



- TENNYSON.
