The bridge swings over the stream "with ease and power." it does not just connect banks that are already there. The banks emerge as banks only as the bridge crosses the stream... The bridge gathers the earth as landscape around the stream. Thus it guides and attends the stream through the meadows... The bridge is a thing; it gathers the fourfold, but in such a way that it allows a site for the fourfold. By this sit are determinded the localities and ways by which a space is provided for.
