WIRELESS LANDSCAPES: MAKING THE INVISIBLE INTELLIGIBLE A practical guide for wavespotters An Inspiration "There are some kinds of knowledge too that cannot be obtained from books, but must be gathered by actual observation. The inspection of a formation in nature, which is pointed out to you, will teach you more in regard to it in a few minutes that you could learn from lectures or from reading books in as many hours, and the lesson so received will be better remembered. "How lonely would be a journey on which you would see not a single face that you know, and how different it would be if every one you meet were an old friend. So to the tourist new charms must be given to scenery, however attractive it may already be, if he knows something about its geology. The rocks, mountains, valleys and plains, although he sees them for the first time, are old friends in perhaps new and interesting forms. He meets them with a certain pleasure, for he understands what he sees and he is given the materials for many a happy hour of quiet and profitable reflection at home, on what he has seen on his railway journey." From An American Geological Railway Guide, by James R. MacFarlane, Ph.D., New York: D. Appleton and Company, 2nd edition, 1890, pp. 3-4.
