In Warren and Sussex counties are abundant materials for the manufacture of Portland cement. In 1934, the chief stone prod ucts were trap rock, limestone, sandstone and granite, having a total value of $1,662,968. The manufacture of iron in New Jersey dates from 1674, when the metal was reduced from its ores near Shrewsbury, Monmouth county. The product of the iron mines in 1934 was only 145,326 long tons.
New Jersey was the first state in the Union to pass (1891) a State aid highway act. Since that early beginning, New Jersey has spent many millions of dollars in constructing and maintaining a State highway system, which on Jan. t, 1935 consisted of 1,351 miles. Of this total 1,269 were surfaced. In 1935 a total of 888, 292 motor vehicles were registered.
The water-borne commerce of New Jersey in 1935 exclusive of that of Hoboken and Jersey City which is included in the port of New York, amounted to 58,472 cargo tons of imports and 64. 656 cargo tons of exports. The chief ports were Bayonne, New ark, Perth Amboy and Carteret.
The first authenticated visit of a European to what is now New Jersey was made under French authority by Giovanni da Ver razano, a Florentine navigator, who in the spring of 1524 sailed within Sandy Hook and dropped anchor in the waters of upper New York bay. In the following year Estevan Gomez, a Portu guese sailor in the service of the emperor Charles V., is said to have made note of the Hudson and Delaware rivers. Voyages to this region for exploration, trade and settlement, however, may be said to have really begun with the year 1609, when Henry Hudson explored the region between Sandy Hook and Raritan bay and sailed up the river which now bears his name. In Cornelis Jacobsen Mey explored the lower Delaware, and two years later Cornelis Hendricksen more thoroughly explored this stream. In 1623 the first party of permanent homeseekers ar rived at New Amsterdam, and a portion of these formed a set tlement on the eastern bank of the Delaware and built Ft. Nassau near the site of the present Gloucester City. On the western bank of the Hudson the trading post of Hobocanhackingh, on the site of the present city of Hoboken, was established at an early date. From these places and from New Amsterdam the Dutch spread into the Raritan valley.
In the meantime colonists of another nationality had set foot on the shores of the lower Delaware. In 1638, 5o Swedish colo nists landed on the western bank of the Delaware and built Ft. Christina on the site of the modern Wilmington. Five years later, on the eastern bank a triangular fort, called Elfsborg, was con structed near the present Salem. But the Swedish rule was short lived, as in 1655 the settlements surrendered to Peter Stuyvesant and passed under the control of the Dutch.
