STUDIES IN EUROPE.* 

 By Bailey Willis. 



Obiect of the journey . — During 1903 and 1904 I had been engaged, 

 under the auspices of the Carnegie Institution of Washington, in 

 geologic research in eastern Asia, and had gathered data which sup- 

 plement previous knowledge of the continent ; to some extent they 

 also qualify both it and the theoretical views published by European 

 geologists. It was desirable to lay the new facts and novel interpre- 

 tations before the leading European students of Asia, in personal 

 conference, and this was one principal object of the journey. 



A second purpose was to extend to Europe studies in comparative 

 geology of continents, already begun for North America and Asia. 

 The particular subject of comparison is that of the age of mountains 

 and the relation generally thought to exist between the internal 

 structure of ranges and their present elevation. This subject is one 

 in regard to which opinions are changing in Europe as well as in 

 America, but more slowly abroad, and I wished to see whether there 

 were other types of mountains there than are found in the United 

 States and China. 



To these ends the journey was planned to visit certain scientists 

 for conference and certain mountain ranges for investigation. 



Itinerary. — Sailing from New York February 4 and going via 

 Naples, I reached Berlin March 5 and remained till the end of the 

 month. Vienna was my headquarters during the first half of April. 

 Leaving there April 16, I returned May 15, after having scanned the 

 phenomena of the Croatian coast, of the northern Apennines, and of 

 the Basse Alps. The latter part of May was spent at Vienna and 

 in an excursion to the Bohemian highlands. May 31 I left for Bel- 

 grade, the Balkan Mountains and Danube Canyon, Constantinople, 

 and beyond as far as Ismid and the Dardanelles. June 19 I returned 

 from Constantinople, and proceeding via Budapest to Neu-Sandec, 

 near Krakau, spent several days in the Karpathians. On the 1st of 

 July I sailed from Cherbourg for New York. 



CONFERENCE RELATIONS AND RESULTS. 



Berlin. — Baron Ferdinand von Richthofen, one of the earliest and 

 best-informed geological explorers of China, 1868-72, had in 1903 

 courteously advised me concerning favorable localities for investiga- 

 tion, and with the broadest scientific interest he welcomed the detailed
