New Mexico, where in after years he spent so many years of his life in 

 the interests of private corporations. The report was published in vol- 

 ume II of the Hayden Survey bulletins, issued in 1876. 



His work in "Wyoming" and Idaho was mainly to the south and south- 

 west of what is now the Yellowstone Xational Park. The Teton Range 

 was the principal object of inquiry. It was found to be a gigantic niono- 

 clinal block having for a nucleus metamorphic and granitic rocks. It 

 formed a lofty, exceedingly rugged ridge, with jagged crest, which culmi- 

 nated in a majestic peak which was named Mount Hayden. 



Among the other ranges investigated in this connection were the Gros 

 Ventre, the Snake River, the Caraboo, and the Blackfoot Mountains. An 

 interesting find was a series of fossils identical with those found along 

 the Mississippi River at Burlington and Keokuk. The presence of the 

 Mississippian rocks were thus recognized for the first time on the Pacific 

 >lope of the continental divide. The report wa.s profusely illustrated. 

 The beautiful outline sketches were the forerunners of Holmes's won- 

 derful productions a few years later. When I went through this region, 

 forty years afterward, with Saint John's drawings before me. I could not 

 but marvel at their great beauty and accuracy. 



In the following year Saint John studied the region lying to the east, 

 chiefly the Wind River Mountains, and made an elaborate report on their 

 geological features. 



At the .close of the field season in Wyoming, Saint John returned to 

 Topeka to write up his notes. Having done this, he turned to put the 

 finishing touches on his monograph on the Illinois fossil fishes. Then 

 he applied himself for several years to an intensive study of the coal- 

 l>earing deposits of southeastern Kansas and the contiguous parts of the 

 adjoining States. 



When officers of the Atchison. Topeka and Santa Fe Railroad heard 

 of his investigations they at once proceeded to engage his services in sur- 

 veying the entire region with a view of selecting and locating the most 

 desirable fuel lands for their own use and for general and industrial 

 purposes. This investigation presented many difficulties, not a few of 

 them seemingly unsurmountable. In this flat-lying, little dissected coun- 

 try natural outcrops of the coal beds were few and far between, so that 

 the existence and depth of possible coals had to be determined largely by 

 inference from strata 1 relations many, often a hundred, miles away. His 

 locations thus made were then verified by systematic drilling over an 

 expanse of many thousands of acres. Thus the great Girard coal field. 

 the greatest in all Kansas, was located and opened up. 



Various other important investigations were intrusted to him from
