May be Reopened After a [Long Period of Idleness.The prospeefca for the reopening of the old Brotherton mine, which has been idle since 1882 or ’83, are good. This mine, which is located about two and a half miles from Doverou the top of Mine Hill, is on the west extension of the old Byram mine vein. In the early days of iron mining in New Jersey this mine was operated and ail the ore to a greater or lesser extent above water level was taken out. The mine was closed by the panic of 1873 and no work was done on the property until 1879, when the mine was reopened by J. Wesley Pullman, of Philadelphia, and Richard George, then of Dover, but now a reel dent of Brooklyn, both of whom, were connected with the Andover Iron Company, The fall in prices of iron following the boom of 1879 again closed tht mine In 1882 or *83, and since then nothing has been done until the present work was begun. The mine Is now being reopened and the work will be carried on by the Bethlehem Iron Company, onie of the strongest companies of eastern Pennsylvania. The old workings are about 160 feet deep. The-ore is. very rich, running over (10 per cent, in metallic iron. It is not a Bessemer ore. but is well adapted for the basic or open-hearth process of steel making. As this process in the past four years has made great inroads on the Bessemer process, such ores as those of the Brotherton mine are valuable and in great demand. The present work is being done under the management and superintendence of David Jardine, of Kenvil, who for rhore than twenty years was superintendent of the Cobb Willis mine, now known as the Wharton mine, at Hibernia, when that mine was operated by the Bethlehem Iron Company,AU former work at the Brotherton mine was done by the moot primitive methods, the water being pumped and the ore raised by horse power. A new pumping plaut is now being installed, a boiler, a steam pump and a small hoisting'engine being already on the premises. It is proposed first to put down a sink to the depth of two or three hundred feet in order to make a thorough test of the workings. In the Byram mine rioh veius were found at a depth of three hundred feet from the surface, and although these were never found in the Brotherton mine, as the workings wore not deep enough, the present operators are Bure they can be found, as the two mines are on the same vein. Although former work inJthe Brotherton mine was done in a primitive way, the prices of iron ■ were at that time so high that a good deal of money was made; If the teats meet a aufU- 1 dent 'degree of success to warrant the expenditure of tho money a switch will be run in from the Ferro Monte Railroad and active operations will be begun. The mine property is owned by J. W. Brotherton, of this town, 1 James Jardine, of Succasuima, and William ' Jardine, of Kenvil.
