1、Can a Papermaker Help to Save CivilizationCan a Papermaker Help to Save Civilization? Each November, a papermaker named Timothy Barrett gathers a group of friends and students on the grounds of the University of Iowa Research Park, a onetime tuberculosis sanitarium in Coralville, Iowa, for what he b

2、ills as a harvest event. Armed with hook-shaped knives, Barrett and his party hack away at a grove of bare, shrublike trees called kozo, a Japanese relative of the common mulberry. At his nearby studio, which is housed in the former sanitariums laundry facility, the bundles of cut kozo are steamed i

3、n a steel caldron to loosen the bark. After the bark is stripped from the kozo, it is hung on racks, where it shrivels to a crisp over a matter of days. Eventually the bark is dehydrated and sliced apart from its middle, “green” layer, and that layer, in turn, is sheared from the prized inner layer.

4、 It takes about a hundred pounds of harvested kozo trees to yield eight pounds of this “white bark, ” from which Barrett will ultimately make a few hundred sheets of what connoisseurs consider to be some of the worlds most perfect paper.Barrett, who is 61, has dedicated his life to unlocking the mys

5、teries of paper, which he regards as both the elemental stuff of civilization and an endangered species in digital culture. For his range of paper-related activities, he received a $500, 000 fellowship from the MacArthur Foundation in 2009. “Sometimes I worry about what a weird thing it is to be pre

6、occupied with paper when theres so much trouble in the world, ” Barrett told me, “but then I think of how our whole culture is knitted together by paper, and it makes a kind of sense.” The Library of Congress and the Newberry Library in Chicago are among the institutions that often use his paper to

7、mend their most important holdings, from illuminated manuscripts to musical scores penned by Mozart. In 1999, officials at the National Archives commissioned Barrett to fabricate paper on which to lay the fragile parchment originals of the U.S. Constitution, Bill of Rights and Declaration of Indepen

8、dence. A visitor to Washington, Barrett said, would be unlikely to notice his paper resting beneath the founding charters. “But if you kind of turn your head sideways and squint, you can see it.”I first met Barrett last winter, when I went to his studio to see him make washi, the lustrous, transluce

9、nt, tissue-thin Japanese-style paper that is the fruit of his mulberry harvest. Washi, he told me, was a centuries-old winter vocation of Japanese rice farmers. A thermostat on a cinder-block wall read 50.2 degrees, and Barrett was wearing a thick long-sleeve undershirt, a flannel shirt and a down v

10、est beneath his heavy apron. He makes washi only six weeks each year, and forms sheets of paper only on Thursdays. Much of the rest of the time he is preparing the white bark according to a regimen that includes cooking it in a solution of wood-ash lye, laboriously picking the strands free of tiny b

11、its of debris, beating them with a mechanical stamping device, pounding them with mallets and then macerating the stringy clumps in a tub outfitted with S-shaped blades that he says are modeled on a medieval Japanese sword.He stepped inside an 8-by-10-foot corner of the studio that was enclosed by c

12、urtains of plastic sheeting and scooped a few liters of wet white bark fibers into a vat of purified water. Then he poured in what he called a “formation agent” plant secretions that, he said, were the key to the amazing strength, softness and flexibility of sheets no thicker than a Kleenex. He stir

13、red the vat with a four-foot pole, then pushed and pulled the prongs of a huge, rakelike wooden tool through the solution to disperse the fibers evenly in the water. “A hundred and fifty strokes, ” he said, though he didnt appear to be counting. He stirred with the pole again and paused. Now he was

14、ready to make a sheet of paper.He took hold of a rectangular wooden frame, or mold, that had a bamboo mat and dipped it into the vat. He lifted it out, let excess water splash over the sides, then plunged it back in. He shook his arms rhythmically. Small waves formed on the surface. He might have be

15、en taken for someone at a washtub, though he swayed in a languid, trancelike manner. Finally, he bent his knees deeply, took one more pull out of the vat and quickly tossed the excess off. Nothing but a wet sheen was left on the mold. I thought that the process had, for some reason, failed to produc

16、e paper. But soon, from a corner of the frame, Barrett peeled off a pale yellow sheet, which resembled a large damp handkerchief. “People are always surprised when they see it for the first time, ” he told me afterward. “Its as though it comes out of nowhere.” By the end of the day he had a stack of 100 sheets or so, which he would drain overnight, clamp in a screw press and dry on a wall of steam-heated sheet metal the following day. The finished product was a rectangle of ra
