ITS WORTH TO THE 

 STUDENT 



It has become a proverb that for a geologist there are three 

 requisites for success: The first is travel, the second is travel and 

 the third is travel. 



The Union Pacific Railroad Company w^as thus contribut- 

 ing to the success of a large number of geologists, when it 

 made accessible to them that open book on geology, the Wyo- 

 ming plains and mountains; and those who were so fortunate 

 as to be able to accept the invitation gained results the value of 

 which it would be hard to estimate. 



All forms of geological phenomena were so well presented in 

 Wyoming as to be well nigh diagrammatic and it would be 

 difficult to say in which department of the science the greatest 

 interest was felt and the greatest profit attained. 



Students of structural geology, who were acquainted with 

 Appalachian and Alpine mountain architecture alone, beheld 

 such monoclines, synclines and antichnes as they had never seen 

 before. 



Students of physiographic geology observed peneplanation 

 on a world-wide scale, and had presented to their view splendid 

 examples of erosion that varied from the cuttings of rivulets 

 through non-resistant regolith to the powerful carving of the 

 Grand Platte through tenacious Mesozoic sandstones and lime- 

 stones, through Paleozoic rocks of similar character and 

 through Archean quartzites and granite. 



The student of economic geology had opportunity to be- 

 come acquainted with Wyoming coal deposits, gypsum beds, 

 various building stones, railroad ballast and road material, and
