transition eras exist; gneisssienite, graywacke, and graywacke slate, calcareous rocks, etc., are the principal formations in the northern region, andcontain vast masses of metals and metallic oxides. Iron in all its forms occurs abundantly, and copper, which appearsin the secondary formations, is also f< innd in considerable quantities. Nearly a century ago, several lumps of virgin copperwere ploughed up near New Brunswick, and a mine, near Belleville, on the Passaic, was discovered as early as 1719.There are many veins in the latter which might be worked with profit, and it is said that these mines contain a goodquantity of silver ore. There is still another mine north of Somen ilk-, which contains, according to Dr. Torrey, a nativecopper, carbonate and phosphate of copper, green and red oxide of copper, native silver, green quartz, chrysophase,phrenite, etc. In the mountain section, which extends in breadth varying from 15 to 35 miles in right angles, with the134 bb*»ki«w***-

THE STATE OF NEW JERSEY. general course of the mountains, the geological formations are strongly blended. Rocks of a pretty uniform characterhowever, are found in the primitive ridges, but they are of a coarse and uneven texture, and surface aggregated withcrystals of quartz and felspar. Sometimes they contain shorl, garnets, hornblende, epodite, and mica. Granite, gneiss andsienite are formed in this section by the blending and combination of these materials; and at some points the primitivegreenstone is seen. The richest and most productive iron mines are also found here; some of the beds are from 8 to 12feet in thickness. There is also found here large quantities of graphite. Black mica is found on the Ramapo River, nearthe Monroe works, and highly magnetic iron ore in Sehooleys and Musconctong mountains. Wallkill Valley, west ofthe Hamburg Mountains, is noted for the number and variety of its minerals. The bottom of the valley rests on whitechrystaline limestone and marble. The fi
