In some places, large depositsare indicated by the magnetic needle.• "*OGDJ_qMINE.The next important deposit of magnetic ore which has beenopened and worked, is.upon the Wallkill Mountain, threemiles southeast of Frankli n F.urnace. It was opened in theyear 1772 by Abram Ogden, and has since then been worked L . D, at intervalsj by different parties, its name always changingwith the name of its proprietor.

It is now workedforty feei from the snrfaes_ and is fifteen feet in v¢idth. Theore which it yields is of a variable quality, some being entirelyfree from foreign substancesj while with a large proportion ofit may be found the constituent minerals of the gneiss_and_i nsome casesi iron pyrites in small quantities. This ore is smeltedin Hopewell Forge.:VULC_r m_."This mine is sltuated on Vulcan Head, on the property of"Richard R.

The firstshaft exposes a mass of ore ten feet in width, dipping towardsthe southeast at an angle, of fourteen degrees. The ore is,highly magnetie_ and contains a considerable quantity of feld-_.par .and.iron pyrites associated with it. ',The second shaftNEW JERSEY GEOLOGICAL SURVEY
