I BELIEVE it was Zeno who said, “We have only one mouth, but two ears; whereby Nature teaches us that we should speak little, but hear much.” So, having two eyes and only one pen, I must see much and write little. I shall not therefore pause, as I should like, to speak of a few charming days spent in walking through the “Black Forests” of Germany, nor of a visit to Heidelberg, beautiful for situation and famous for its university, “Half hidden in a gallery of pines, Nestling on the sunny slope.” There is no more impressive sight in Germany than the ruins of the Heidelberg Castle. The remains of its frowning battlements, ivy-covered walls, and hanging gardens speak most eloquently of its former greatness and grandeur. I can never forget the moonlight nights that Johnson and I spent in Heidelberg, wandering up and down the banks of the Neckar, listening to the music of her waters as they flow on to join the legendary Rhine, a few hundred yards below. Leaving Heidelberg at four o’clock in the morning, we travel all day through a comparatively uninteresting country, reaching Basle, Switzerland, in time to break bread with a friend (?) who kindly sent a committee to the depot to meet us. The committee insisted on carrying us up from the station in a carriage, but we told them that as we had no exercise during the day, we preferred to walk and carry our own satchels.
