Bridges as walls The biographer of Robert Moses, Robert A. Caro, refers to the bridges and underpasses of the famed New York State parkways. These bridges and underpasses are quite low, intentionally specified by Moses to allow only private cars to pass. All those who traveled by bus because they were poor or black or both were barred from the use and enjoyment of the parkland and its "public amenities" by the technical design of the bridges. Even at the time of Robert Moses, a political statement of the form "We don't want them blacks in our parks" would have been unacceptable in New York State. But a technological expression of the same prejudice appeared to be all right. Of course, to the public the intent of the design became evident only after it was executed, and then the bridges were there. Ursula M.

The palette of nature "What nature does with its colors is invariably—the palette of nature is twice as complicated, at least twice as sophisticated, as anything any artist can ever come up with. On a couple levels. To start with, there are these amazing combinations of colors, filled with surprises and almost never wrong. I don't know how Nature ever conceived to put, say, those together. But, boy, are they right on the money!" Lawrence Wechler & Robert Irwin, Seeing Is Forgetting the Name of the Thing One Sees Colors in natureHues subdued naturecolor
