The noblest use to which feathers have been adapted has been in the production of writing instruments. The antiquity of the pen, regarded as a feather, is shown in the proof recently set forth by the philologists. _Penna_ is the Latin for feather; farther back an instrument for flying is called _patna_; the Sanskrit which became _penna_ in the Latin tongue became _phathra_ in the mouths of the Teutonic peoples. So the English language, which is formed from both Latin and Teutonic elements, possesses two words, _pen_, and _feather_, which were one in their origin, have been widely separated during the ages, and now are united, but in such a way that only under the microscope of comparative grammar are we able to discover that they have the same blood in their veins. Although the people living in warm countries wrote with the reed, the Chinese with a brush, and we have learned to fashion steel so it will do the work to better advantage, yet the feather has been a mighty agency in the civilization of the world. Every teacher used to consider it one of the essentials of his equipment to possess a good penknife and know how to use it in making or mending pens for his pupils. Quills were first carefully cleansed from all oily or fatty matter and then dried. A gentle heat was applied to secure the brittleness which made it possible to split the pen point without spoiling the quill. In Russia and in Holland quills were dipped in boiling alum-water or diluted nitric acid and then dried and clarified in a bath of hot sand. Goose quills were most used, turkey quills were prized by many, and swan quills were considered the best of all. Pens well made from swan quills often sold as high as four guineas a thousand, while goose quill pens were to be had at twenty shillings. For fine writing, crow-quills were considered best, and pen-and-ink drawings were generally produced with the black-plumed article. In 1832, to supplement the domestic products in the manufacture of pens, 33,668,000 quills were imported into England. The trade has not been entirely killed by the advent of the steel pen, for there are yet among us representatives of the people of the olden time who delight in the pretty little squeak of the quill pen as it assists them in their literary labors. Man early learned to rob the birds of their coverings, not only for adornment, but also for warmth. Feather beds were once reckoned as evidences of wealth. Modern science has pointed out the unhealthful condition of a bed made soft and gaseous with feathers. Few beds are now found of this sort among the better-informed people of America, but the traveler in the northern countries of Europe not only has to sleep on feathers but also under them. The down coverlet is as essential to a Danish bed as is clean linen.
