QUOTE : In travelling where novelties of all kinds press in upon us, mental food is often supplied so rapidly from without that there is no time for digestion. We regret that the quickly shifting impressions can leave no permanent imprint. In reality, however, it is with this as it is with reading. How often we regret not being able to retain in the memory one-thousandth part of what is read ! It is comforting in both cases to know that the seen as well as the read has made a mental impression before it is forgotten, and thus forms the mind and nourishes it, while that which is retained in the memory merely fills and swells the hollow of the head with matter which remains ever foreign to it, because it has not been absorbed, and therefore the recipient can be as empty as before.
