far perfected by the inventor and others, and the demand for them so 

 much increased, that now, in a neighboring town, at least one dozen 

 of these machines are turned out weekly, and sold to manufacturers 

 of carpets and other woolens; and we have no doubt that one of these 

 purifying machines will, within a few years, piecede every machine 

 card for woolens in the country, effecting a saving in the destruction 

 of cards amounting to some hundreds of thousands of dollars per an- 

 num. 



Another machine alluded to has been invented more recently still, 

 in this country; we refer to a machine invented in this city by Mr. 

 Emmons, for the purpose of preparing worn out or damaged wool- 

 ens, silks, &,c., in a manner suitable for re-manufacturing into cloth. 

 Damaged or cast-off linens and cottons find a ready market for re- 

 production into paper. Refuse woolens have been comparatively 

 valueless, (although such a machine has been in use in Europe for 

 several years, but strictly monopolized by England;) with this ma- 

 chine, tons of this waste, may be converted into cheap carpets, and 

 old silks be made into handkerchiefs for a numerous class. 



A machine of great ingenuity was brought out in Cambridge, 

 Mass., last summer, for sewing cloth. In effecting this object, the 

 author has invented a new and beautiful stitch, on which account 

 the machine possesses additional interest. We look for the adoption 

 of this machine in the manufacture of clothing by the trade in large 

 cities. 



Such have been the results in the space of half a century, of the 

 combination and co-operation of these various machines and improve- 

 ments of machines for the production of wearing apparel, that the 

 distinctions of society arising from the nature of dress, are now no 

 longer known by the quality of a coat a man wears. The middle 

 classes, the mechanic and the laboring man, are seated side by si<le 

 with the wealthy in our churches and other places of public resort, 

 without offence to decency or propriety. 



I pass from this principal head of my subject, raiment, to notice 

 what has been done in the same space of time for increasing the fa- 

 cilities of producing food. Under this head, we commence with the 

 oldest in the catalogue — the grist-mill. 



All the essential improvements in these mills and other kindred 

 machines for grinding grain or preparing the same for food, have pro-
