FIBRE-PRODUCING PLANTS--SOURCES OF SUPPLY.

The high value of land precludes the cultivation of any fibrous

material exclusively for paper-making in England, even if this climate

was suitable for its growth; with the exception indeed of "FLAX" and

"HEMP," it would appear that northern latitudes are not favourable for

the production of fibre-producing plants, and therefore it is to warm

or _tropical countries_ alone any reliable supply of "NEW MATERIAL" can

be looked for.

In the _East_, and _West Indies_, in her _Colonies_ and _Dependencies_,

England possesses an inexhaustible supply of fibre-producing plants; in

India especially, almost every plant abounds more or less in fibre.

In China and Japan, as also in India, from the earliest times, paper

has been made exclusively from _raw indigenous virgin fibres_, and the

paper produced in these countries is in consequence generally extremely

strong and tough, and although unbleached, and not made in a fashion

adapted to European requirements, affords ample and conclusive evidence

of the valuable supply of material at our disposal.

VEGETABLE FIBROUS, or FIBRE-PRODUCING PLANTS, are divided by BOTANISTS

into two distinct CLASSES or DIVISIONS: ENDOGENS, or inside growers;

EXOGENS, or outside growers.

From the former are obtained the fibres known as "MANILLA HEMP" or

"ABACA" (from the _Musa textilis_ or _Plantain_), the "ALOE," "AGAVÉ"

(or "_Pita_ _Fibre_"), the "YUCCA," "BROMELIA PENGUIN," "SISAL HEMP"

(or _Hannequin_); "PINA FIBRE" from the "PINE APPLE" (_Ananassa

sativa_), "MAROOL or MOORVA" (_Sanseveira Zeylanica_), "NEW ZEALAND

FLAX" (_Phormium tenax_), &c.; "MAIZE" (or _Indian Corn_), "RICE,"

and other "CEREAL STRAWS," "ESPARTO," "DISS," and various "Sedges,"

"Reeds," and "Grasses," the latter including "BAMBOO," and "SUGAR

CANE," are also comprised in this Class.

The FIBRES, or FIBROUS TISSUE enveloping the _Stems_ of _Herbaceous

Plants_, known as "HEMP," "FLAX," "JUTE," "HIBISCUS," (_Gombo_ or

_Okhro_), "RHEA," or "CHINA-GRASS" (_Urtica nivea_), "SUNN HEMP"

(_Cratolaria juncea_), &c., as also the LACE BARKS (so called), such

as the "ADANSONIA DIGITATAS" (from the _Baobab_ tree), the "NEPAL

PAPER PLANT" (_Daphne cannabina_), the "PAPER MULBERRY" (_Broussonetia

papyrifera_), &c., constitute the latter Class.

I have confined myself to recapitulating _a few only_ of the _fibres_

in either class, best known to commerce; this list, indeed, might be

extended almost indefinitely, as may be seen by reference to the work

before alluded to, 'The Fibrous Plants of India,' by Dr. Forbes Royle,

as also to the elaborate Paper on the same subject, read at the meeting

of the Society of Arts, May 9, 1860, by Dr. J. Forbes Watson, Reporter

on the Products of India, Dr. Royle's able successor.

With some few exceptions (notably "Esparto" and some of the Cereal

straws and grasses), the resulting or ultimate fibres from vegetable

fibrous plants, before they can be utilized either for Textile

purposes, or for the manufacture of Paper, must be freed from the

extraneous substances with which during their growth they are more or

less combined.

In the case of _Endogens_, the fibres are imbedded or enveloped in

succulent, fleshy, or pulpy stems, or leaves; and in the case of

_Exogens_, the fibre is combined with, and attaching to, wood, or woody

matter, such extraneous substances or matters constituting, more or

less, a considerable portion both of the weight and bulk of the plant

even when matured.
