The Rogers Ruin of Mercer County

The Rogers House is a fine example of 18th century pattern brick architecture that unfortunately was neglected long enough that by the time funding was acquired, the only option was to preserve it as a stabilized ruin. Mercer County acquired the house in 1970; the preservation project was not completed until 2019. Still, a stabilized ruin is better than a collapsed house.

“Pattern brick” means that letters and numbers are built into the walls using glazed brick ends inset among unglazed brick stretchers. On one end is “1751” commemorating when the house was built (although there has been debate about whether the third digit is a “5” or “6”). On the opposite side are the letters “J + R R” for John and Rachel Rogers, the original homeowners. The rest of the walls are built a Flemish bond with alternating brick headers and stretchers.

Cadwalader Park’s Abandoned Animal Paddocks

Frederick Law Olmstead did not want a zoo in the park he designed for the city of Trenton, but Trenton gave the people what they wanted anyway. These barns were added later and housed exotic deer and other animals into the 21st century. Recent work has restored the natural areas, but the abandoned and decaying animal barns remain in place for now.

This little suspension bridge, which spans the attractively named Waste Weir, was built by the Roebling Company. Some internet sources say it is a miniature replica of one of Roebling’s more famous projects, either the Brooklyn Bridge or the Niagara Bridge. Although it uses the same suspension technology, the design is not identical. Other sources say it was built to demonstrate suspension technology, and then given to the city of Trenton. I haven’t seen a firm date for when it was built.

The Shaky Bridge sits between the Delaware River and Route 29 in Stacy Park. Route 29 runs over the alignment of the Trenton Water Power, a seven mile long canal completed in 1834  – the same year as the 65 mile long D&R Canal.

Radiotelephone Service to Europe and Beyond: The Pole Farm in Lawrence, New Jersey

The original telephone system connected phones by copper wire strung up on poles. These “land-lines” faced a problem when confronted with obstacles like the Atlantic ocean, so it was not possible to connect the phone systems of distant countries. In the 1920s, AT&T developed a way of using short wave radio to transmit telephone signals over long distances without wires. In 1928, AT&T bought several farms in Lawrence, New Jersey, cleared the land, and began building a vast antenna array for trans-Atlantic telephone calls. The facility, officially called the American Telegraph & Telephone International Radio Telephone Transmission Station, was only responsible for calls originating in the United States. A separate facility in Netcong, New Jersey, received incoming calls from overseas.

The Lawrence station became known as the Pole Farm because the rhombic antennas that AT&T installed at the site were arranged in a diamond-shaped pattern on wooden poles up to ten stories tall. Each antenna covered 10 acres and connected New Jersey and the rest of the U.S.A. with a single city in Europe, North Africa, the Middle East, or South America. Hundreds of these poles were arranged over the 800 acre facility. Open areas between the poles were leased to farmers, who had to plow around the many antennas.

Fewer than 50 calls were made on an average day in 1929, in part because a three-minute call to England cost over thirty dollars. The station, however, allowed almost instantaneous communication across the Atlantic Ocean (once trained telephone operators had arranged the connection). By the 1960s, however, international calls were more affordable and over 16,000 telephone calls were transmitted daily through the Pole Farm.

The Pole Farm shut down in 1975, replaced by undersea cables and satellites. Where once there were hundreds of wooden poles, there is now only one. That pole, which once transmitted phone calls to Israel, survived because the farmhouse next to it used it as a lightning rod.

The last pole.

Two buildings, imaginatively named Building One and Building Two, bracketed the antenna field. Both buildings have been demolished, but a memorial to the facility, built over Building One, includes a large concrete and stone map set into the ground, showing the layout of the antennas around the time of World War II. Each antenna is labeled with the city to which it transmitted phone calls.

The Pole Farm is now part of the Mercer Meadows county park and features restored grasslands, nature trails, and interpretive signs.
