336&#93; |6] PAP olher refuse from the stalks of hemp, may be made into a good and strong packing-paper. In or- der to improve shaws, they ought to be dried in an oven; wlien the small, woody particles should be separated, by beating them with thin sticks ; next, the clean and pure material must be suffered to putrefy, and afterwards treated in a manner similar to old rags. — FoKDi, an Italian author, relates, that from shaws alone, he obtained a paper resembling the finest sort manufaftured in Holland, after ex- posing them to the open air, for a whole winter : thus, from time to time, a white pellicle appeared on the surface, till tlieir woody sub- stance is entirely decayed ; this co.1t or skin should be occasionally removed, being one of tlie best substitutes for linen r.-ig5. — Press- lonrdj have, in this country, always been manufaftured of s/iain ; and we have no doubt but that the lat- ter may be rendered subservient to more valuable purposes. 5. Hnp-ihiCS : — Dr. ScHAEFFER plunged them for fifteen minutes in boiling water, then separated the rind from the woody substance, cut the latter into small pieces, and sent it to the engine. After being worked eight hours, they became fibrous, pulpy, and were fit to be formed into paper : on adding rags, the sheets assumed a whitish ap- pearance; bur, without them, had a brownish shade, and were uni- formly of a firm consibtence. 6. The. stalks of Brown or Blue Call-age, when deprived of their external skin, macerated for twelve hours in lime-water, then reduced to a pulp, afford, with the 20th part of rags, a good white paper. 7. The dry down of the C.^x's- TAiL ; — See vol. i. p, 458. PAP 8. The stalk of^iheMallow, anct particularly those oft hcAlcea rosea, L. from which a tine and white paper may be prepared, without adding any rags. 9. Ma'ite : from the leafy husk of this fruit, according to Plancus, the most beautiU.l post-paper i.s prepared in an Italian mill, near Iximini. — Schalffer made an ex- periment with the whole plant, and obtained a greyish paper: but. after steeping the pulp four days in hme- ■water, the sheets acquired a green- ish slmde. 10. From the woolly catkins of the irhite Poplar, Schaeffer also obtained an excellent smooth paper; having previously cut them into sm.all pieces, and then submitted them for three hours to the opera- tion oftheengine: he remarks, that the pulp was easily drawn, formed into sheets, pressed, sized, &c. The paper made of the woolly substance produced by the Black Poplar, was grey, and neitloer firm, nor free from k-obs. 11. The stalks of the. Common Broom, after depriving them of the. external rind, atford, without rags, a .solid writing-paper. 12. The Shaics n/Flax, together with other refuse from that ar- ticle, have lately been used with advantage by the Germ.an paj)er- makers: it is well known, that the stalks of the fiax-plantmay be em- ployed in their natural state for this purpose ; but the expence would not be equivalent to the profit : hence the shaws ought not to be thrown away as useless. 13. The stalk of the Common 5//7?-^o«'a-(Helianthus anuuus,L.) contain a large po; tion of a white, shining, fibrous substance, which, more than any otlier, deserves the attention of the manufadurer. 14.
