are =East Newark=, =Harrison=, and =Kearney=, the last including =Arlington=. These municipalities are located in Hudson County and are, therefore, officially connected with Jersey City as its county seat. But they are much nearer Newark, with which they are closely connected by industrial and commercial ties. They are prosperous manufacturing centers with industries of national importance. In =East Newark= the most important manufactures are sewing thread and shade rollers. In Harrison the industries are varied and the products include iron and steel, incandescent lamps, steam pumps, roller bearings, elevators, steel and tin toys, electric wire, trunks, brass products, tools, metal novelties, castings, and machinery. In =Kearney= the important manufactures are linoleums, yarns, twine, glue, oils, fertilizers, ships, and castings. [Illustration: Jersey City as seen from the Hudson] =Jersey City and its Environs.=--A long narrow peninsula lies between the Hudson River and New York Bay on the east, and the Hackensack River and Newark Bay on the west. On this peninsula are located many prosperous cities. On the southern half, which is in Hudson County, is found the most densely populated part of the state, with many large cities of great industrial and commercial importance. =Jersey City=, the largest of this group, had, in 1910, a population of 267,779, and in 1920, according to the United States Census, 297,864. It is the second city of the state in size, and twenty-first in the United States. Parts of it were occupied by the Dutch soon after New York was settled, but the first permanent government was established in 1660 at Bergen, which is now a part of the city. Here were also established the first school and the first church in the state. It is located on New York Bay and the Hudson River and extends westward from these waters to Newark Bay and the Hackensack River. It has a frontage on tidal waters of about twelve miles and has therefore unexcelled facilities for transportation by vessels of any size to all the seaports of the world. Thirteen railroads have terminals in the city. Besides these, there are eleven other passenger and freight stations in the city. Here the railroads bring the products of all parts of the country directly to the ships which sail to all parts of the world.
