A great deal has been heard in this State lately about the Steteleidt Fur-nice, Fur-nice, says the bite I'ine X, us of November -1st. and feme pei'.-ons have an idea that it is used for .-melting ores, but as this is not the ease, we give below a iU'-ci iptbm of its o instruction in-struction and use.
