CLOSE OF THE HAYDEN SURVEY 
TRIP TO EUROPE 
1879-1880 
On June 3G, 1879, the Hayden Survey of the Territories, 
which had been for several years actively engaged in Rocky Moun- 
tain surveys, was discontinued by Congress. The Arny Engineer 
Survey under the direction of George M. Wheeler was closed at 
the same time and the U. S. Geological Survey was established 
by Congress, with Clarence King as Director. Although my work 
on the old Survey was not completed, I resolved to take a year off 
for a trip to Europe, the principal objects of the trip being to 
visit the museums and galleries of the principal cities, and to 
study art. The second six months of 1879 and the first six 
months of 1880 were devoted to this outing. 
Provided with necessary passport and letters of intro- 
duction, the latter by Professor Baird, Dr. Hayden, Mr. Donald- 
son and others, I sailed August 2, 1879, and landed at Liverpool 
August 21. 
My diary note books of the period give elaborate details 
of my do ings , but, as with those of other periods, they were too 
voluminous to be preserved or copied, and for the most part have 
been destroyed, and my many sketches in pencil and water color 
have been widely scattered. 
I had a pleasant voyage, no sickness at all. In London 
I visited the galleries, museums and public places generally, 
leaving on August 24 for Dover and thence for Calais, Brussels, 
Aix La Chape lie, Cologne, Dusseldorf, Zermatt (September 14).
