“ Throughout his long and industrious life, Alexander von Humboldt has ever retained his love and devotion for the country where his great field of labor lay, and for its people to whom he always felt so closely connected by his love for freedom in thoughts and for liberty. It is a well-known fact that in his later days of all foreign people who ever knocked at his door no one was more heartily welcomed than the American citizen. ”
