From copper mine to steamboat, the New Jersey ventures of Nicholas Roosevelt

When inclement weather forces us Hidden New Jerseyans to curtail travel, we often turn to other means of exploration. The reference books and histories we've picked up over the years aren't quite those roadside markers we stop to check out on county roads, but they've got some unexpected gems, nonetheless.

One of my new favorites is the New Jersey Almanac Tercentenary Edition published by the Trenton Evening Times in 1964 to commemorate the state's 300th anniversary. Besides giving an illuminating look at life in the Garden State 50 years ago, it contains lists upon lists of interesting tidbits like two-sentence bios of notable New Jerseyans, brief descriptions of towns and cities, and a year-by-year guide to events of importance.

It's an entry in that last category that caught my eye during a recent snowstorm. The big event for the year 1794 is: "Nicholas Roosevelt made first steam engine ever built entirely in America at his shop "Soho" in Belleville."

Roosevelt? As in Teddy Roosevelt and FDR? The New York Roosevelts?

Absolutely. Nicholas Roosevelt was not only the cousin (several generations back) of both Presidents Roosevelt, you could say he was one of New Jersey's first industrialists.

Born in New York in 1767, Roosevelt's first foray into New Jersey was in the early 1790s, when he became linked to what, even then, was thought of as the old Schuyler Mine in North Arlington. Originating in 1719 when an enslaved worker on Arent Schuyler's farm found a copper nugget on the property, the mine closed in 1772 after a disastrous fire. Roosevelt and partners formed the New Jersey Copper Mine Association in 1793 to restart mining operations at the site, a venture that ultimately failed.

Though the mine was a disappointment, it was the stepping stone into New Jersey that led to Roosevelt's greater acclaim. Purchasing land in Second River (now Belleville), he built a foundry, smelter and machine shop to build steam engines. Dubbed Soho after a similar enterprise in Birmingham, England, the shop became known as one of the nation's top foundries, supplying engines for notable clients like the Philadelphia Waterworks. The business took a severe financial hit, however, when a government contract to supply rolled copper for warships was cancelled.

Among those taking note of the quality of Soho's engines was transportation engineer John Stevens. Already experimenting with steam-driven boats, he and his partner Robert Livingston commissioned Soho in 1797 to build an engine for the Polacca, a craft with a stern-mounted propeller. Roosevelt was already familiar with self-propelled boats, having experimented with spring-driven paddleboat technology as a youth. When the Polacca proved to be much slower than anticipated, Roosevelt advocated the use of a side-mounted wheel, but Livingston refused to consider the concept.

Roosevelt had, indeed, come up with a solution so workable that it was later adopted by Robert Fulton. You might recognize that name: he's the engineer who's usually linked most directly with the successful development of the steamboat. I've seen a few different accounts of how this came to be, but the most interesting one is that Livingston suggested the side-mounted wheel to Fulton without telling him where the idea had originated. And according to a website citing sources at the FDR Library and Museum, some Roosevelt family members continue to claim that Nicholas was the true inventor of the steamboat.

It's not clear exactly when Roosevelt left New Jersey for good, but by 1810 he'd entered into a partnership with Fulton and Livingston to run a steamboat down the Mississippi River. He died in Skaneateles, NY in 1854, his contributions to steam powered technology now largely forgotten while other inventors continue to enjoy acclaim.

I just wonder what other gems are hiding in the Tercentenary Almanac, just waiting to be unearthed.

You'll never take it alive: Copper in Watchung Reservation*

Union County's Watchung Reservation is well known among New Jersey adventurers as home of the Deserted Village, but it holds other surprises that aren't as evident, even when you practically trip over them.

If you take a right turn after the trail head near the Trailside Nature and Science Center, you'll eventually come upon a bunch of ravines. They look entirely natural, but one isn't quite what it appears to be. In fact, it's the last remnants of a very old copper mine. You'll know you found it when you come upon the interpretive marker (if it's still there) or a four-by-four post with a pink stripe around it (if it's not). Oh, and you might notice some rocks with a slight greenish tinge on them, that being the traces of very low-quality copper.

The area isn't as well known for mining today as other parts of the state are, but its history goes far back. Park literature theorizes that the First Watchung Mountain ridge may have been scouted for copper by the Lenape as far back as 500 years ago. Another source noted that the area was first settled by English miners in the 1600s. Either there was really something there, or speculators were highly motivated to take a chance at making a big strike in the New World. I'm betting on the latter more than the former.

The more interesting story, in my book, is what may have happened there during the Revolutionary War. It's believed that Hessian prisoners of war were held in what's now Mountainside, and brought to the mine site to dig for copper for military use. The famed Schuyler Mine in the North Arlington area was closed at the time, and perhaps the Continentals thought they could hit pay dirt farther south along the ridge. In any case, the Hessians only got about fifteen feet in before digging was halted; the ore they found was deemed not to be worth the time to extract, transport and process. If there were any other mining attempts within the current reservation borders, they're not evident today.

As I was researching the Reservation's mining history, I found the usual apocryphal mine stories: deep underground rooms haunted by a kid who got lost and trapped by a cave-in, you name it. All that tends to go out the window when you see the actual location. If there's someone stuck in there, he's been there for an awfully long time.
