mentioned,) the straw is then boiled with quick lime in ~ater, for t h e purp~se of e~tracting the colouring matter, and separaiing its tlbres. Caustic potash, soda, or ammonia may be employed for tiffs purpose, instead of lime. When this is done, i t i s t d b e ~ a s h e d i n clean water, m order to remove the colour that has been extracted, and also the slaked lime. The fibrous substance is rhea submitWd to the action of a hydro-sulphuret, composed of quick lime and sulphur in s.lution, in the proportion of four ounces of qui,:k lime to one of sult)hur, with one quart of water, in order to gfiet rid of the mucilaginous and silicious matters. After this the ()rous material must be thoroughly washed in successive waters, ulml all the alkaline matters are removed, and there is no smell o f the sulphur left; this may be done by beating in a paper mill, or bv any other econonfical means : it is then pressed to extract the Water from the fibres, and bleached in the or(library way, either "with chlorine, or with lime, or by exposure to the light and air, upon a grass plat. The bleaching process having been completed, the material is again washed until all chymical matters are entirely removed from i t when it is considered fit to be introduced to the ordinary rag engine, employed in making paper, for the purpose of reducing it to pulp~ previously to moulding it into sheets.
Dressing Hats by] Jllachincry. A Patent has been granted to El)WARD OLLERE~SVIAW,Of Manchester, tlat Manufacturer, for a method of dressing and finishing hats, by means of machinery. To effect this, the hat is fixed upon a block in the usual manner ; the centre piece of the block i s fnrnished with a screw, by which it may be attached to a lathe, it is then made to revolve with a slow continuous motlon, aqmkinz ab,)ut twenty turns in a minute; the workman holds i a his leit hand, a small cushion covered with plusli, which he applies to the hat on the far side, whilst the hot iron is passed in succession over every part of the crown. When t h i s is finished the hat is fixed upon a horizontal lathe, where the tip or fiat top of the hat is dressed in the way before described ; it is then removed to a third sl,indle, running horizontally, and furnished with a suitable support for the brim, the top surface of ,which is then finished. To complete the operation, the hat is removed to another horizontal lathe, prepared to receive the crown, so that the lower part of the brim may be turned upwards, it being at the same time properly supported by a rim of wood in a suitable shape. It is now made to revolve with about half the former velocity; which, whilst it presents every part in succession to the workman, admits of his (lrawin~ the heated iron, fi'om the inner, towards the outer edge of the bTim. Each of these operations is repeated a second time, when the dressing is completed.
