Mark Twain 
A Tramp Abroad [EPUB ebook] 

One day it occurred to me that it had been many years since the world had been afforded the spectacle of a man adventurous enough to undertake a journey through Europe on foot. After much thought, I decided that I was a person fitted to furnish to mankind this spectacle. So I determined to do it. This was in March, 1878.
I looked about me for the right sort of person to accompany me in the capacity of agent, and finally hired a Mr. Harris for this service.
It was also my purpose to study art while in Europe. Mr. Harris was in sympathy with me in this. He was as much of an enthusiast in art as I was, and not less anxious to learn to paint. I desired to learn the German language; so did Harris.
