  • Quill Pen and Nut Ink
    Children of Early Appalachia Quill Pen and Nut Ink Grades 3 and up Early writing tools were made from materials people could find or easily make themselves. Children used a slate with chalk and stone to write lessons at schools. They also practiced drawing and writing with a stick in dirt. Penny pencils for slates were available at general stores. Paper was purchased at stores too. Before the invention of pencils and pens, children used carved twigs or goose-quill pens made by the teacher. Ink was made at home from various ingredients (berries, nuts, roots, and soot) and brought to school. Good penmanship was highly valued but difficult to attain. Objective: Students will make pen and ink from natural materials and try writing with these old- fashioned tools. Materials: Pen: feathers, sharp scissors or a pen knife (Peacock or pheasant feathers make wonderful pens, but any large feather from a goose or turkey works well too.) Ink: 10 walnut shells, water, vinegar, salt, hammer, old cloth, saucepan, small jar with lid, strainer. (After using the homemade ink, students make like to continue practicing writing with the quill, so you may want to provide a bottle of manufactured ink for further quill writings.) Plan: Pen: Cut off the end of the feather at a slant. Then cut a narrow slit at the point of the pen. Ink: 1. Crush the shells in cloth with a hammer. 2. Put shells in saucepan with 1 cup of water. Bring to a boil, and then simmer for 45 minutes or until dark brown.

  • The Origins of the Musical Staff
    The Origins of the Musical Staff John Haines For Michel Huglo, master and friend Who can blame music historians for frequently claiming that Guido of Arezzo invented the musical staff? Given the medieval period’s unma- nageable length, it must often be reduced to as streamlined a shape as possible, with some select significant heroes along the way to push ahead the plot of musical progress: Gregory invented chant; the trouba- dours, vernacular song; Leoninus and Perotinus, polyphony; Franco of Cologne, measured notation. And Guido invented the staff. To be sure, not all historians put it quite this way. Some, such as Richard Hoppin, write more cautiously that “the completion of the four-line staff ...is generally credited to Guido d’Arezzo,”1 or, in the words of the New Grove Dictionary of Music, that Guido “is remembered today for his development of a system of precise pitch notation through lines and spaces.”2 Such occasional caution aside, however, the legend of Guido as inventor of the staff abides and pervades. In his Notation of Polyphonic Music, Willi Apel writes of “the staff, that ingenious invention of Guido of Arezzo.”3 As Claude Palisca puts it in his biography of Guido, it was that medieval Italian music writer’s prologue to his antiphoner around 1030 that contained one of the “brilliant proposals that launched the Guido legend, the device of staff notation.”4 “Guido’s introduction of a system of four lines and four spaces” is, in Paul Henry Lang’s widely read history, an “achievement” deemed “one of the most significant in

  • Handwriting Today . . . and a Stolen American Relic
    Reviews Handwriting Today... and A Stolen American Relic WILLIAM BUTTS FLOREY, Kitty Burns. Script and Scribble: The Rise and Fall of Handwriting. Brooklyn: Melville House Publishing, 2009. 8vo. Hardbound, dust jacket. 190pp. Illustrations. $22.95. HOWARD, David. Lost Rights: The Misadventures of a Stolen Ameri- can Relic. Boston: Houghton Mifflin Harcourt, 2010. Small 4to. Hardbound, dust jacket. 344pp. $26.00. If you’re anything like me, handling handwriting from many eras on a daily basis, you get sick and tired of the endless refrain from the general public when viewing old documents: “People all had such beautiful handwriting back then!” or, conversely, “No one writes like that today!” Et cetera—ad nauseum. I’ve almost given up refuting these gross generalizations, but “in the old days” I’d pull out letters from, say, Horace Greeley, the Duke of Wellington, a Civil War soldier and other notori- ously illegible scribblers to prove that every age has its share of beautiful penmanship, horrid penmanship and mediocre pen- manship. And as for modern penmanship, most of the examples of current penmanship I see are in the form of personal checks MANUSCRIPTS, VOL. 62 235 NO. 3, SUMMER 2010 236 MANUSCRIPTS (thankfully), and there too I find a mix of beautiful, horrid and mediocre penmanship. The more things change, the more they you-know-what. Which is one beef I have with Kitty Burns Florey in her oth- erwise enjoyable Script and Scribble: The Rise and Fall of Handwrit- ing. Other than the uninitiated general public cited above, the other group that unfairly bemoans current penmanship are the handwriting snobs (which I don’t consider Florey)—elit- ists whose devotion to pseudo-Palmerian calligraphy or other esoteric specialties blinds them to the simple, honest, unsophis- ticated attractiveness of the day-to-day script of ordinary persons who’ve never studied calligraphy.

  • The History of the Ballpoint Pen
    89 | Ezra’s Archives My Utilitarian Chinese Memento: The History of the Ballpoint Pen Robert Schur Made in China For all intents and purposes, my three-week sojourn through China should have given me an appreciation for the Chinese people and their culture, a more thorough understanding of life under a Communist regime, and perhaps some knowledge of handy Chinese phrases. Indeed, I left the country with all of those things, but I also found myself fascinated with the most mundane of souvenirs: the ballpoint pen, particularly the one that I acquired while studying at Zhejiang University in Hangzhou, China, during a trip with fifty other Cornell students sponsored by Cornell University and the Chinese government. When we arrived for our orientation, we found each place set with an array of official University and government forms. Next to these stacks of paper rested green triangular ballpoint pens filled with blue ink, sporting retractable points, each emblazoned with the university’s name, phone number and website. Considering my at-best-rudimentary Chinese language skills, this pen proved quite handy, as I would have been at a loss to ask a hotel clerk or cashier to borrow one. Beyond this small bit of good fortune, I thought little of the pen as I carried it in my pocket throughout the trip until I was making notes on a lecture by one Dr. Wu Xiaobo about the Chinese economy. As he detailed the various aspects of China’s post-Mao era economic reforms, he informed us that 80 percent of all of the world’s pens are made in China, and 70 percent of The History of the Ballpoint Pen | 90 worldwide pen components are made in a particular district, the name of which my sloppy handwriting ironically rendered unintelligible.1 While the veracity of Chinese economic statistics has been hotly contested recently, and reliable data on Chinese ballpoint pen manufacturing data is all but nonexistent, Wu’s remarks nonetheless made me reconsider the oft-overlooked history of the pen that I held in my hands, just one of the billions of ballpoints across the world.

  • Making a Quill Pen This Activity May Need a Little Bit of Support However the End Project Will Be Great for Future Historic Events and Other Crafting Activities
    Making A Quill Pen This activity may need a little bit of support however the end project will be great for future historic events and other crafting activities. Ask your maintenance person to get involved by providing the pliers and supporting with the production of the Quill Pen. What to do 1. Use needle-nose pliers to cut about 1" off of the pointed end of the turkey feather. 2. Use the pliers to pluck feathers from the quill as shown in the first photo on the next page. Leave about 6" of feathers at the top of the quill. 3. Sand the exposed quill with an emery board to remove flaky fibres and unwanted texture. Smoothing the quill will make it more pleasant to hold while writing. 4. If the clipped end of the quill is jagged and/or split, carefully even it out using nail scissors as shown in the middle photo. 5. Use standard scissors to make a slanted 1/2" cut on the tip of the quill as shown in the last photo below. You Will Need 10" –12" faux turkey feather Water -based ink 6. Use tweezers to clean out any debris left in the hollow of the quill. Needle -nose pliers 7. Cut a 1/2" vertical slit on the long side of the quill tip. When the Emery board pen is pressed down, the “prongs” should spread apart slightly as Nail scissors shown in the centre photo below. Tweezers Scissors Keeping it Easy Attach a ball point pen to the feather using electrical tape.
