q41the wire mills the blooms are worked add drawn down to thefinest wire, unsurpassed in quality ; steel of the best descriptlonis also produced from the iron ; and when wrought ironof great strength and toughness is required, as in. the shahs forour largest class steamers, the Andovcr iron has been thoi'-oughly tested and pronounced unrivalled."The Trenton Iron Company have three furnaces atpresent iu operatidn, requiring to sup'ply them sixty thousandtons of ore per annum. A large proportion of this ore is _kenfrom the Andover mines, yet" notwithstanding this heavy demandupon them, the mines promis.e to yield for many yearsto come an abundant supply._tJAMES C.KENT."' . 8LIMONITE--IiYDROUS PEROXIDEOF IRON--BOGIRONORE---YELLOWCLAY IRON STONE.This ore, when pure, is composed of the hydrous peroxideof iron, and contains about sixty parts of metallic iron in onehundred. It almost always occurs mixed with foreign substances,as lime, alumina, sillc% &c., which give to it a varietyof forms, and from which its name is derived. Its prevailingcolors are various shades of brown and'yellow ; and its streakand powder areyellow brown. The variety called bog oresometimes contains phosphorus, and yields a cold short iron,unfit for those purposes which require a tough tenacious metal,but admirably adapted for c_ting. This ore, in its variousforms, occurs in beds associated with rocks of all ages. Inthis district the greatest deposits are found among the metamorphicrocks of the Wallkill Valley. Bog oi'e occurs, notunfrequently, in the Blue Mountains; and in the valley of theDelaware, but not in sufficient quantities to be of much practicalimportance.'On the farm of Chandler Wood, half a'milo southwest ofthe New Turnpike, on the Blue Mountain, is a bed of this oreapparently of considerable extent. It is situated in a marsh atNEW JERSEY GEOLOGICAL SURVEY
