MANUFACTURE S.

Tron. One of the moſt- celebrated foundries in Europe was eſtabliſhed 35 years ago, on the banks of the river Carron, in this county. The cheapneſ of fuel,(pit-coal), was probably the cauſe of fixing that great mannufa&ory in this diftrit. The benefit of water-carriage muſt alſo have been an additional inducement.--The raw materials em- ployed in theſe works are various kinds of ironſtone and limeſtone, brought from different parts of Scotland; and jron-ore from Lancaſhire and Weſtmoreland. During the firlt 25 years of this eſtablihhment, the coals were got in the immediate vicinity of the works, in no inſtance exceeding one mile of carriage, and that upon waggon-ways.

The blaßt-furnaces are no fewer than five. In- ſtead of ſupplying the quantity'of air neceſſary for theſe furnaces, by the uſual mode of large bellows made of lea- «her, this Company introduced the uſe of large iron cylin- ders, the operation of which, in forcing air into the fur- 2 NACCS,
