The Jersey Devil may be a figment, but it’s an admirably hard-working one. Since 1840 the creature has been haunting the southern Pine Barrens, killing livestock, leaving strange tracks, flying, barking, attacking trolleys, eating chickens, biting dogs, and generally expressing a vituperative disapproval of Garden State settlement.

Its appearance matches its disposition. This drawing was made for the Philadelphia Evening Bulletin in 1909, but eyewitnesses have also reported a ram’s head, a long neck, thin wings, short legs, thick black hair, a monkey’s arms and hands, a dog’s face, split hooves, a foot-long tail, and “the general appearance of a kangaroo.”

Laugh if you will, but don’t underestimate it: To date the Devil has been shot, electrocuted, and hosed by the West Collingswood fire department, but sightings have continued through 1991, when a pizza deliveryman encountered a white horselike creature in Edison. Watch your back.

Predictions made by John Titor, a “time traveler” from 2036 who appeared briefly on the Internet in 2000 and 2001:

• The United States will go to war with Iraq over claims that the latter has nuclear weapons, and these claims will later prove false.
• Civil unrest will follow the presidential election of 2004, escalating into civil war in 2005.
• The war will pit cities against rural areas, with the government controlling the cities.
• When the old system cannot be restored, a new president will take power in 2009.
• As American support for Israel wavers, a nuclear war will occur in the Middle East.
• China will take over Korea, Taiwan, and Japan.
• In 2015 there will be a global nuclear war among United States, China, Europe, and Russia. Nearly 3 billion people will die.

“Perhaps I should let you all in on a little secret,” he wrote. “No one likes you in the future. This time period is looked at as being full of lazy, self-centered, civically ignorant sheep. Perhaps you should be less concerned about me and more concerned about that.”

On the other hand, he also claimed that Y2K would lead to martial law and that “Russia is covered in nuclear snow from their collapsed reactors.” So, maybe not.

What is this? Is it a spider monkey? Or is it some unknown primate? We may never find out — this is the only photograph that survives from a strange encounter in the Venezuelan jungle in 1920.

Swiss oil geologist François De Loys was exploring near Lake Maracaibo when two creatures angrily approached his camp. The animals behaved like monkeys, holding onto shrubs and branches. The male escaped, but De Loys shot the female, which proved to be 1.57 meters tall, about half a meter larger than any known spider monkey. He said the creature had no tail, though it’s impossible to tell from the single photo he took.

All traces of the creature itself are lost — De Loys skinned it and kept the hide and skull, but he lost them during the difficult expedition (20 of the 24 explorers died).

Since then, authorities have argued endlessly about “Ameranthropoides loysi” — but it’s worth noting that that’s a regulation crate it’s sitting on, which supports De Loys’ contention about its size, and that its face, chest and hands differ in significant respects from a spider monkey’s. And there have been occasional reports of similar creatures in South America: “Mono Grande” may yet be discovered there.

This is Malden Island, an uninhabited speck of land more than 1,500 miles from Hawaii. When Lord Byron’s cousin discovered it in 1825, he found a series of ruined stone temples in the interior, but the island was deserted. Who were the builders, where did they come from, and what became of them? No one knows for sure.

A U.S. forest ranger in Virginia’s Shenandoah National Park, Roy Cleveland Sullivan (1912-1983) survived being hit by lightning seven different times:

1. In a lookout tower in 1942, the first bolt struck him in the leg. He lost a nail on his big toe.
2. In 1969, a second bolt struck him in his truck, knocking him unconscious and burning his eyebrows.
3. The third strike, in 1970, hit him in his front yard, burning his left shoulder.
4. The next bolt struck in a ranger station in 1972 and set his hair on fire. After that, he began carrying a pitcher of water with him.
5. In 1973, a bolt hit Sullivan in the head, blasting him out of his car and again setting his hair on fire.
6. The sixth bolt struck him in a campground in 1974, injuring his ankle.
7. The final bolt hit him in 1977, when he was fishing. He was hospitalized for burns on his chest and stomach.

Sullivan shot himself in 1983 … reportedly over a rejected love.

At 5:12 p.m. on November 26, 1977, an unidentified voice appeared on the transmitters of Southern Television in the United Kingdom. Identifying itself as Vrillon, representative of the Ashtar Galactic Command, the voice broke in to a news broadcast to warn viewers of “the destiny of your race,” “so that you may communicate to your fellow beings the course you must take to avoid a disaster which threatens your world and the beings on other worlds around you.”

Accompanied by a deep buzzing, the voice warned against the use of nuclear weapons and stated that humanity had “but a short time to learn to live together in peace and goodwill” before it destroyed itself.

Investigators decided that pranksters were behind the broadcast, aiming a transmitter at a VHF receiver to overpower the “official” signal with a joke message.

But no one knows for sure.

If you’re visiting Rhode Island, you might be excused for wanting to visit Jerimoth Hill: It’s the highest point in the state.

Unfortunately, you’d be taking your life in your hands. Jerimoth is private property, and it’s owned by a singularly cranky 77-year-old named Henry Richardson, who monitors the trail with motion sensors. Here’s how he’s greeted other visitors:

• Assaulted them verbally (“Shoot all the damn highpointers!” “Get the hell off my property!”)
• Threatened to break cameras
• Started fistfights
• Let the air out of their car tires
• Shot them with rock salt
• Chased them through three states by car

Under pressure, Richardson’s son agreed in 1998 to let hikers visit the highpoint on national holidays. Before that, the 812-foot rise “was considered less accessable than Mt. McKinley.”
