in Scotland , almost the whole of the edge tools used, being broughtfrom Sheffield or Salisbury , where the art of manufacturing everything of this nature has arrived at great perfection.
Cutlers may be divided into two classes, lsf, Those who re-main stationary in the different towns; and, id, Those who tra-vel from place to place with portable cutling machines, whichare wrought by the foot.
The first class are chiefly superior workmen, employed in fa-bricating surgical instruments, scissars, pen-knives, razors, &c.of a good quality and high price. The second class are itinerantworkmen, who grind knives, scissars, razors, and other edgedinstruments, and make a livelihood in this way, in the streetsand lanes of the different cities and towns of Scotland .
As the English manufacturers principally supply the Scotchmarket, both for exportation and home consumption, with cut-lery and hardware articles, the extent of these branches of theiron trade, as well as the number of workmen employed, is in-considerable.

1. Copper .—Although there be many indications of this me-tal in different parts of Scotland, and the Islands , yet copper-mining has hitherto only been attempted at Arthrey in Stirling-shire, and in Fair Isle, one of the Zetland Islands , where, in thespace of two years, from June 1802, about 473 tons of ore wereraised. This mine lias been abandoned ; but in the opinion ofseveral well informed people, it might still be wrought with ad-vantage. Copper has likewise been found in the Ochil hills, nearStirling, All the copper, however, used in Scotland by copper-smiths, and for copperplate printing, ship-sheathing, 8tc. is ob-tained from England and Wales .
The use of copper culinary utensils has been much supersededof late years, by those made of tinned plate and cast-iron, ow-ing to their cheapness, and the danger to be apprehended fromthe oxidation of copper vessels. The coppersmith trade, how-ever, still continues to support itself, chiefly by the numerousorders obtained for boilers and distilling apparatus for the WestIndies , &c. and for home consumption. Copper tea kettles, cof-fee-pots, backets, goblets, scales, scoops, measures, and similararticles, are made to considerable extent for both foreign andhome sale, besides various pipes for the different chemical, bleach-ing, printing, and other works.
2. Lead .—The application of lead is very extensive in the ma-nufacture of ridges, gutters, rain-pipes, roofing of domes, andother parts of buildings, cisterns, conduit pipes, &c. The fa-brication of these articles is properly the business of the plumber,who uses tin for soldering the lead. Tin has not been found in
