 becomes more difficult to cleanse. The washing must be carefully performed, so as to prevent the fibre from becoming tangled or knotted. The operation of washing or rinsing must be repeated until the fibre be thoroughly cleansed. If it be found difficult to clean the fibre from the extraneous matter, in consequence of not collecting the leaves from the plant sufficiently early, or from any other cause, the operation will be facilitated by boiling the fibre, after it has been beaten, and partially purified in a solution of soap in soft water. For this purpose the fibre must be regularly disposed in any suitable vessel, so as to prevent its becoming tangled, with sufficient water to cover it, in which soap has been dissolved, in the proportion of about 5 lbs. to 50 lbs. of fibre, a light weight being then placed upon it, to keep the fibre beneath the surface of the liquor; the whole is then to be boiled for the space of three or four hours, and after boiling, to be well rinsed out in soft water, and squeezed as before directed. The fibre having been cleansed by these processes, is to be gradually dried in the shade, and occasionally shaken out, so as to prevent the too close adhesion of the filament in drying, which would otherwise take place. The fibre may be obtained free from the extraneous matter of the leaf by other modes; but I prefer that which I have above described. As to the second part of my said invention, it is only necessary to observe that from the ''superiority of this fibre in several respects over those now in common use'' (?), it is adapted to a vast number of purposes, in which fibrous materials are now employed; it is of a glossy white color, it receives dyes with facility, it possesses great strength, and is divisible to an exceeding degree of fineness, for upon examination each filament that appears a single fibre, is, in fact, a bundle of very delicate fibres, adhering more or less strongly together. These qualities render it applicable to the manufacture of shawls, drills, damask-linens, plushes, carpets, rugs, lace, bonnets, paper; as a material for rope, twine, or thread, and a variety of other purposes to which silk, cotton, flax hemp, wool, and other fibrous materials are now applied. As a material for spinning in the ordinary method in which flax is now spun through hot water, this fibre requires to undergo the process generally in use for
