and by about 1790 the art became what we have it to-day, one purely for indoors. The new method was first practised successfully in the neighbourhood of Bolton, which place has preserved its original reputation, though long since rivalled in every part of the cotton-manufacturing district, and often in more distant spots, a copious supply of clean water being indispensable, and outweighing in its value the advantages of proximity to town. Many successive steps have to be taken before perfect whiteness can be secured, these demanding the utmost care and the strictest order of procedure. Finally, unless destined for the dye-house or the print-works, the cloth is stiffened with starch made from wheaten flour, the consumption of which article is very large also in the factories, where it is employed to give tenacity to the yarn, reacting beneficially upon the agricultural interest; then, in order to give it the beautiful smoothness and gloss which remind one of the petals of the snowdrop, it is pressed between huge rollers which play against one another under the influence of powerful engines. On emerging from them it is said to have been "cylindered," or, corruptly, "calendered." Bleaching, it will appear from this, is a process which but slightly taxes human strength. Very interesting is it to note how, in the presence of chemistry and steam, the old word "manufacture" has in modern times changed its meaning. To-day the office of human fingers is less to "make" than to guide the forces of nature, all the harder work being delegated to inanimate wood and iron. The time ordinarily allowed for bleaching is one or two days, though, if needful, the entire process can be accelerated. The cost is about a halfpenny per yard. Dyeing is carried on in Lancashire quite as extensively as bleaching. Here, again, the exactest chemical knowledge is wanted. The managers are usually men well versed in science. A visit to an important dye-works always awakens the liveliest sentiments of admiration, and were it not for the relentless fouling of the streams which receive the refuse, few scenes of industry would live longer in pleasant memory. For although dye-works exist in towns and their suburbs, they are more frequently established out in the country, where there are babbling brooks and "shallow falls," with a view to obtaining a plentiful and steady supply of clean water. Factories also are sometimes found amid the fields, occupying quite isolated positions, the object being similar--the command of some definite local advantage. When at the foot of a hill it is interesting to observe that the chimney is placed half-way up the slope, a preliminary underground passage inducing a more powerful draught.
