The camp dog was the first to hear it. In the bunkhouse behind Hennefield, the door stood open because the night was warm, and from inside came, very faintly, the sound of Lazaro Quincy humming in his sleep. And from down the path that led through cedar and hemlock to the lake, the same tune came back, note for note, rising through the dark toward the clearing. Hennefield stood with the lantern in one hand and the rifle in the other, and he could not tell which sound was leading and which was following.

He knew only that the elder had been right, that the door was not a metaphor, and that if he took one more step down that path, he would not be coming back up it. It had not begun that way. In the late summer of 1894, a stretch of forest in the upper peninsula of Michigan already had a reputation among the men who worked it. Compasses spun there in slow, patient circles, and the men who went in to find out why never quite came back the way they went in.

Some came back quiet, some came back wrong, and some did not come back at all. The story of what happened at the logging camp that does not appear on any modern map, near a lake the Ojibwe asked outsiders never to name out loud, survives in ledgers, a few water-warped letters, and one recorded warning from a tribal elder that the company foreman wrote down in his own hand and then ignored. The man at the center of it was named Cornelius Pellegrew, 44 years old, a timber cruiser by trade, the man who walked ahead of the logging crews to mark which pines were worth the saw and which to leave standing. He was tall for his time, six foot one, narrow through the shoulders, with a long sunburnt face and a beard he kept short with a straight razor every Sunday, whether the camp had hot water or not.

His hands had spent 26 years inside a forest and did not quite uncurl all the way when they rested on a table. He had a soft voice and almost never raised it. The men who worked under him said you could tell Cornelius was angry only because he got quieter, never louder. He had been hired that summer by a Detroit timber concern called Voss and Halliburton, which had bought up almost 12,000 acres of old growth white pine north of a small lake the Ojibwe called by a word the company clerk wrote phonetically in his ledger as Wenag.

There is no Wenag on any map today. The clerk admitted later he was not sure he had spelled it right. He also admitted he wished he had never written it down at all. Cornelius arrived at camp on the 3rd of August.

The crew was already in place: 41 men, a cook, two teamsters, and a blacksmith named Otho Renquist, who had come up from Ohio and would later become one of the only men to walk out of those woods with most of his sense still intact. The foreman, the man Cornelius answered to, was a company man named Ulrich Hennefield, 61 years old, broad and slow-moving, with a head of white hair and a habit of writing everything down. Every word spoken to him by a stranger, every sound heard at night, every bad dream a man reported. It is because of Hennefield’s small leather notebook, which his widow donated to a regional historical society in 1922, that any of what happened next is known.

The camp sat on a low rise about half a mile back from the lake. There was the bunkhouse, the cook shack, a long open shed for the saws and axes, a stable for the four draft horses, a separate cabin for Hennefield because foremen always had their own cabin, and a path that led down through cedar and hemlock to the water. The first three days, Hennefield wrote, were uneventful. The men cleared a skid road.

Cornelius walked the eastern boundary of the lease, marking pines with a chalked X. The cook, a man named Hosmer Plow, complained about the flies. The flies were terrible that year. Hennefield wrote that down too, because Hennefield wrote down everything.

On the fourth day, the elder came. His name, as Hennefield rendered it, was Ahonu Wabasha, a man perhaps 70 years old, walking with a stick of black ash, accompanied by two younger men who said almost nothing. He came up the skid road in the middle of the afternoon when most of the crew was out in the timber, and he asked, in good and careful English, to speak to the man in charge. Hennefield offered him coffee, which the elder declined.

He offered him a chair, which the elder accepted. The two younger men remained standing, one on either side of him, their eyes on the trees. What the elder said that afternoon is preserved almost word for word in Hennefield’s own handwriting. “There’s a place in the woods to the north of this camp that you have already started to cut,” the elder said.

“You have not yet reached the worst of it. You will reach it within 10 days, perhaps 12. When you reach it, you will know it. The trees there grow in a different pattern.

The ground is damp even when there has been no rain. There is a smell. You will not be able to name the smell, but you will know it is wrong. The animals do not enter that place.

The deer do not cross it. The crows do not fly about it. If you continue to cut there, you will lose men, not to accidents, to something else. We do not say its name out loud because the word is a kind of door.

I will not say it now, here, near your camp, because the door is easier to open than to close. Take your men. Take your horses. Mark the cut you have already done and leave the rest.

If you stay, by the next full moon, the men you brought with you from the south will not all walk out of these woods. Some will be lost. Some will come back, but not as themselves. ”

Then the elder stood, took his stick, nodded once, and left, the two younger men walking behind him.

They did not look back. Hennefield watched them go down the skid road until the trees swallowed them, then sat for a long time in the chair the elder had used and wrote down everything the elder had said twice, to make sure he had it right. He did not tell the men. In the margin he wrote, “I do not believe in such things, but I do not wish to frighten the crew.

I will tell Pellegrew alone tonight. ”

That night, after supper, he told Cornelius. Cornelius read the page twice, set the notebook down, and asked one question. “Did the old man seem afraid?

”

Hennefield wrote afterward that he had not thought of it that way, but yes, now that it was asked, the old man had not seemed afraid at all. He had seemed tired, the way a doctor seems tired after telling a family bad news for the third time that week. Cornelius said nothing for a long time. Then he said, “I’ll walk that part of the lease tomorrow, the northern stand.

I want to see it before we send the saws up there. ”

The next morning, the 5th of August, Cornelius left at first light with a compass, a marking axe, a flask of water, and a man named Lazarus Quincy, 28 years old, half French, half Cree, hired as a scaler, who knew that country better than anyone else in the crew. They were supposed to be back by dark. They were not.

Hennefield held supper. The men ate without them. At full dark, Hennefield lit a lantern on the post outside his cabin and sat on the step with his rifle across his knees, listening. The woods were quiet that night, not silent, because the woods are never silent in August, but quieter than they should have been.

At a little past three in the morning, by Hennefield’s pocket watch, Cornelius walked out of the trees alone. His coat was torn, his marking axe was gone, and his left hand was bleeding from a long shallow cut across the palm that he could not, when asked, account for. He told Hennefield that Lazarus Quincy was alive and probably still walking, but that they had become separated about four miles north of camp and he had spent most of the night walking south without a working compass. When Hennefield asked what had happened to the compass, Cornelius held it up.

The needle was spinning slowly, patiently, in a perfect circle, as if it were being turned by a hand that had all the time in the world. It did not stop spinning the entire time Hennefield was looking at it. Lazarus Quincy walked into camp the following afternoon. He was unhurt physically, but he could not, when pressed, account for any of the previous 20 hours.

He remembered leaving with Cornelius. He remembered drinking from a creek. He remembered, he said, smelling something bad, something like wet iron and old hide. And then he remembered nothing at all until he found himself walking south along the skid road in the middle of the morning alone, with a piece of birch bark folded into a small tight square in his pocket.

Birch bark he did not remember picking up. He gave the bark to Hennefield, who looked at it, put it into the back of his notebook between two pages, pressed the notebook flat under a stack of ledgers, and did not look at the bark again for nine days. When he finally did, he found pressed inside a thin layer of something dark and dried. The consistency, he wrote, of resin, but darker.

He scraped a little off with his pocketknife. It smelled like wet iron and old hide. The next several days were what the men later called the quiet days, the lull. The crew kept cutting in the southern half of the lease.

Cornelius went out alone every morning, walking different sections, marking pines, coming back at dark with his face a little harder set than the day before. Lazarus Quincy did his work as a scaler but did not speak much, and at night he sat near the cook fire with his back to the trees and would not turn around even when spoken to from behind. Hosmer Plow complained that things were missing from his pantry: a tin of lard, a sack of flour, a small mirror he kept on a shelf to shave by. Otho Renquist, the blacksmith, said two of the horses had begun rolling their eyes back in their stalls at night and refusing to drink from the trough nearest the path that led down to the lake.

The horses were watered from the second trough after that, and they drank fine. Hennefield wrote in his small, careful hand that he believed nothing the elder had said and that nothing strange was happening. He wrote it three times in three days. The third time, he underlined it.

On the 11th of August, six days after the elder’s visit, exactly within the window the elder had named, the saws reached the northern stand. The first man to walk into it came back out within twenty minutes. His name was Phineas Ault, 37 years old, a sawyer from Saginaw with a wife and a small house he had been building on his own land for three summers. He came back to the cook shack pale and sweating and refused to go back into that section of forest.

He told Hennefield the trees up there were wrong. That was the word he used, wrong. The trunks did not stand the way pine trunks stand. They leaned slightly, all in the same direction, and the direction was not the direction of the prevailing wind.

The ground felt soft in places where it should have been hard. And he had heard, very faintly, the sound of someone humming. Not singing, humming. A tune he did not know, but that he could not get out of his head, and that he could still almost hear even now at the cook shack, if he stopped talking.

Hennefield asked him to stop talking briefly, to test it. Phineas Ault stopped talking. After about ten seconds, his face changed. He started talking again, faster than before, and asked Hennefield to please not ask him to be quiet again.

Phineas Ault left camp the next morning, walking out alone with his pack and his pay docked for early departure, refusing to say goodbye to anyone. He did not, as far as Hennefield’s later inquiries could determine, ever work in timber again. He returned to his small, unfinished house outside Saginaw and lived another 41 years, and was known in his village in his old age as a man who would never, under any circumstances, sleep with his window open. He never told anyone what tune he had heard humming.

The day after Ault left, Cornelius took four men into the northern stand himself. Hennefield wrote down their names: Cornelius Pellegrew leading; Otho Renquist the blacksmith, because Hennefield trusted him and because Otho asked to come; a teamster named Bartholomew Vredy, 29, because he was the strongest man in camp and Hennefield wanted strength along; a scaler named Ignatius Colmar, 33, who had logged in Wisconsin for ten years and had seen, he claimed, almost everything a forest could show a man; and Lazarus Quincy, who insisted on coming, although Hennefield did not want him to, because Hennefield was afraid of what going back into that part of the woods might do to a man who had already lost twenty hours inside it. They left at dawn. Hennefield stayed at camp.

He wrote while he waited. “I do not know what I am hoping they find. I do not know what I am hoping they do not find. I am, at this hour, 54 years old.

I have a wife in Cleveland. I have a daughter married to a banker in Toledo. If I do not see them again, it will be because of a job I took for $42 a week and not for any reason I would wish to explain to a priest. ” He did not write again that day.

The men came back at dusk, four of them. Ignatius Colmar was not with them. Cornelius walked into camp first, his face the color of dry birch. Otho came behind him, one hand on Bartholomew Vredy’s elbow, because Vredy was walking but not, as Hennefield put it, fully present.

Lazarus Quincy came last, humming a tune under his breath. Hennefield could not place it. He did not ask Lazarus to stop, because he remembered what had happened with Phineas Ault. They sat the men down, gave them coffee, gave them whiskey.

Then Cornelius spoke for almost an hour. This is what he said, as Hennefield wrote it down. “We went north until we hit the creek, and we crossed it. And we went on for another 40 minutes through ordinary woods.

And then the woods stopped being ordinary. It was not a line you could draw on a map. You walked, and the air thickened. That is the only word, thickened.

The flies stopped. The flies had been bothering us all morning, and then, at one step, they were gone. The birds were gone, too. We stood there, and we could hear nothing but ourselves.

The trees changed. Ault was right. They lean, all of them, in a slight tilt, the same direction, like they have been pushed by a wind that is not blowing now. And the bark on them is wrong.

There are marks on the bark, like long, thin scratches very high up, higher than a bear could reach, higher than two bears could reach, one standing on the other. The ground where you would expect needles and moss is bare in patches, smooth, pressed flat, like something has been lying down there, something heavy, something long. We walked into it. We were moving slow.

Colmar was talking. Colmar had been telling us a story about his sister’s wedding to keep us all level-headed. Colmar stopped talking mid-sentence, and we all turned around to look at him. He was looking up, and we looked up, too.

There was nothing there, just trees, just sky. But Colmar would not look back down. He stood there with his neck bent and his mouth open, and he did not move. And Otho went over to him and put a hand on his shoulder, and Colmar, very calmly, without taking his eyes off whatever he was looking at, said, “It is much taller than I thought it would be.

”

Those were the last words he spoke. We took him by the arms, both of us, Otho and me, and we turned him around, and we started walking him back south. He came with us, walking, his feet moving, but his head stayed turned. He kept looking back.

We could hear his neck, the sound of it. We did not look up again ourselves, no matter how much we wanted to. We just kept walking. About 10 minutes south, the air thinned out again, the flies came back, the birds came back.

And Colmar, the moment we crossed back into the ordinary woods, sagged in our arms like a man who had been holding a heavy thing for hours. We let him sit. We gave him water. He drank.

He said, very quietly, “I am not coming back to camp. ”

Otho asked him what he meant. Colmar said, “I left it back there. I cannot leave it back there.

I am going to go and get it. ”

We tried to hold him. He was not strong. He should not have been able to break my grip.

He broke my grip. He stood up and he walked, not ran, walked back north into that thicker air, and he was gone before we could follow him three steps. We followed him. We followed him for a hundred yards, and then his footprints stopped.

Not turned, not faded. Stopped. Like he had been lifted. We searched.

We called. We waited until the light started to fail, and then we came home. ”

Hennefield wrote it down word for word as best he could remember that night, after the men had been put to bed and the fire built up high and two extra lanterns hung on the post outside his cabin. At the end of the entry he wrote, “I do not understand what has happened to Ignatius Colmar.

I do not believe he is alive. I do not believe he is dead. I believe something has happened to him that does not have a word in our language. I am going to send the men out tomorrow with rifles, and we are going to look for him because we owe him that, but I do not expect to find him.

And if we do find him, I do not expect him to be the man we lost. ”

The next morning, the 13th of August, Hennefield put together a search party of eight men. He was careful to leave four men behind to guard the camp, although when he wrote the word guard, he stopped his pen, sat for a moment, crossed it out, and wrote attend instead, because he was not sure what they were guarding against and was not willing to commit, even on paper, to the idea that something might come the other way. They did not take Lazarus Quincy.

Lazarus had not stopped humming. He was eating, drinking, working, but humming low under his breath all day, and Otho had told Hennefield privately that the tune was getting longer. New notes were being added, as if Lazarus were learning it from somewhere, as if he were slowly, slowly being taught. The search party reached the creek, crossed it, and walked north for 40 minutes through ordinary woods.

Then, exactly as Cornelius had described, the air changed. Hennefield wrote down his impressions before they faded. “The first thing one notices is that one’s own breath becomes audible, loud, as if the silence is so complete that only one’s body remains to be heard. The second thing is the smell.

It is faint at first, a smell like wet iron and old hide, the same smell Quincy reported. The third thing, which I noticed only after several minutes, is that I could not feel the breeze on my skin, although I could see far off the tops of the trees moving as if there were a breeze. The wind was up there. It was not down here.

”

They walked north. After about 20 minutes they found a place where the ground had been pressed flat in a long oval shape, perhaps 15 feet long and 4 feet wide. The pine needles had been pushed out from under it, as if by a great weight. There was no print, no claw mark, only the depression.

Around it, four pine trees had been scored. All four at a height of about 11 feet, with parallel grooves a hand’s span apart. The grooves were deep enough to put a thumb into. The bark inside the grooves was not torn.

It was peeled, removed, as if by something patient. They did not find Ignatius Colmar. They found his hat, hanging from the lowest branch of a young hemlock about 30 yards north of the pressed oval, eight feet off the ground, perfectly placed as if set there by hand. There was no body near it, no blood on it.

On the inside of the brim, where his initials had been stitched by his sister, there was a thin film of something dark and dried, the consistency of resin but darker. It smelled like wet iron and old hide. They took the hat. They did not take anything else.

They turned south. As they walked back, Hennefield noted, none of them were speaking. They had not agreed not to speak. They had simply, the moment they turned south, all of them together, stopped speaking.

It was as if the place had taught them, in the short time they were in it, that voices carried in there in a way they did not carry in ordinary woods, that voices were doors themselves, and that the fewer doors they opened on their way out, the better. About halfway back to the creek, Bartholomew Vredy stopped walking and said, in a voice that was not his voice, the words, “He is still up there. ” Hennefield underlined that part. Vredy’s own face came back to him within a second or two.

He blinked. He looked at them. He said, in his own voice, “Did I just say something? ” And they told him what he had said.

And he turned the color of cold ash. And they walked the rest of the way back to camp without speaking. Vredy did not eat that night. At dawn, Hennefield gave him his pay and a horse.

Vredy rode south and never came back. He died in the fall of 1907, in his sleep, in his own bed, in a small house outside Grand Rapids. His widow said he had slept poorly for the rest of his life. Sometimes, in the middle of the night, he would sit up in bed and say, very clearly, “He is still up there.

” Then he would lie down again, and in the morning he would not remember saying it. On the night of the 13th, after the search party returned, Hennefield took out the bark again by lantern light and unfolded it the rest of the way. The first time he had only opened it part way, stopping when he saw the dark resin. He had not noticed that the bark was folded a second time inside.

When he opened it now, he found scratched into the inner surface, scratched, not written, a small symbol. He drew it in his notebook carefully three times to make sure he had it right. He wrote underneath, “I have shown this to no one. I will show it to no one.

I do not know what it means. I do not know who scratched it into the bark. I do not believe Lazarus Quincy scratched it himself because Lazarus Quincy, when I asked him whether he could read or write, told me he could neither. But the lines are deliberate.

The hand that made them knew what it was doing. I do not believe the bark was placed in his pocket by accident. I believe it was placed in his pocket as a warning by someone or something that wished him to leave the woods or perhaps wished through him to warn us all. I am keeping the bark in my desk.

I am not opening it again. ”

On the morning of the 14th, three more men packed and left. They did not give a reason. They did not even ask for their full pay.

They simply walked out together before the sun was fully up and took the long road south. Hennefield watched them go and did not stop them. The camp now had 32 men plus Cornelius, plus Hennefield, plus the cook. Cornelius came to Hennefield’s cabin that afternoon, sat across the table from him, and said, “We should leave.

” Hennefield agreed, but the company would not allow it. Hennefield wrote a telegram, sent it from the nearest village by hired rider, and received a reply the following morning. It was from a Voss and Halliburton vice president named Rutherford Ainslie, who had never, as far as Hennefield knew, set foot in a forest in his life. The reply said, “Unacceptable.

Continue work. Every day of delay costs company $300. Reports of superstition do not constitute basis for abandonment. If foreman Pellegrew unable to maintain crew, replacement will be dispatched.

”

Hennefield read the telegram twice, folded it, put it inside his notebook. He went outside and stood on the step of his cabin, looking north into the trees for a long time. Then he went back in and wrote, in a hand that was, for the first time in his careful notebook, slightly unsteady. “I will not be the man who tells these men to go back into that place, but I will not be the man who walks them out either.

Because if I do, I lose my position and my pension and my house and the small life I have built for my wife and my daughter. And I am ashamed to say not enough of a man to do that for the sake of a thing I do not even fully understand. So I will do what cowards have always done. I will wait.

I will hope for a sign clear enough that no reasonable man, even Ainslie, could ignore it. ”

The sign came at 3:27 in the morning on the night of the 15th of August. Hennefield was awake because he had not been sleeping much, sitting at his table fully dressed with a lantern lit and his rifle across his lap, when the camp dog began to bark. The camp dog was a long-legged hound named Posey, owned by Hosmer Plow the cook.

Posey barked at deer, at strangers, sometimes at the wind. But her bark that night was a bark Hosmer Plow had never heard from her before. It was the sound, Hennefield wrote, of a dog who had seen something she did not have a category for. The bark went on for perhaps 15 seconds, rising in pitch, and then stopped.

Not faded. Stopped. As if the dog had been picked up. Hennefield went outside with the lantern.

The dog was at the edge of the clearing by the path that led down to the lake, frozen, not running, not barking now, head low, ears flat, tail tucked, looking up the path, not down it. Up. Hennefield raised the lantern. There was nothing on the path that he could see.

He took two steps forward. Posey did not follow. He took two more steps. He stopped.

He listened. He heard, very faintly from somewhere down the path, the sound of someone humming a tune. He did not recognize it. But behind him in the bunkhouse, where the door was open because the night was warm, he heard very faintly Lazarus Quincy humming the same tune in his sleep.

The tune in his sleep was matching, note for note, the tune coming up the path. Or the tune coming up the path was matching, note for note, the tune in his sleep. Hennefield could not tell which. He stood there with the lantern in one hand and the rifle in the other.

He did not move. The humming continued. He thought about his wife in Cleveland, his daughter in Toledo, the $42 a week, the small life that depended on it. He understood in that moment, in a way he had not fully understood before, that the elder had been right.

The door was not a metaphor. Something had been called by the cutting, by the saws, by the bark with the symbol on it, by the men’s voices going into a place that did not want voices in it. Whatever had taken Ignatius Colmar had not finished. And he understood, with a very clear and very cold certainty, that if he took one more step down that path, he would not be coming back up it.

He turned around. He picked up the dog, who let him, because the dog was beyond fear by then. He went to the bunkhouse. He shook Cornelius awake.

He shook Otho awake. He spoke quietly, so as not to wake Lazarus, who was still humming. He said, “We are going now, tonight. Pack what you can carry.

Leave the rest. We are walking out. ”

Cornelius said, “What about the company? ”

Hennefield said, “The company can find another foreman.

I will not be the man who gave any more of these men to that place. ”

Otho said, “What about Lazarus? ”

Here Hennefield’s notebook gets hard to read. The handwriting changes.

The lines crowd together. In places the ink has been smudged by what looks like the heel of a hand pressed flat in haste. He wrote, “We took Lazarus. Of course, we took Lazarus.

We woke him. He walked. He was not himself, but he walked. The humming did not stop, but it became softer the further south we went.

We left at 4:00 in the morning. We took both lanterns and one rifle and what food we could carry. We left the horses because we did not trust the horses to be quiet. We left the saws and the axes and the cook’s pots and the company ledgers and Hennefield’s own desk and, God forgive us, the bark with the symbol on it, which Hennefield realized only later he had left in the desk drawer in his abandoned cabin.

”

They walked south on the skid road, 35 men including the cook, including the dog. They walked all night, through the dawn, through the morning, stopping only to drink and not even sitting down then. They reached the village by dusk on the 16th of August. They slept in a barn.

They were given soup. They were given blankets. None of them spoke much. In the morning, Hennefield sent another telegram to Voss and Halliburton.

He told them the camp had been abandoned. He told them why. He told them he would not be returning and they could keep his last month’s pay. He went home to Cleveland.

He never worked in timber again. He lived another 28 years and died in his bed in 1922 of pneumonia, in the company of his wife, his daughter, and his small grandson. His small leather notebook was on the bedside table. He had read it, his widow later said, almost every night for the last two decades of his life.

Voss and Halliburton sent another foreman. They sent two more, in fact, over the next three years. The first, a man named Wilford Pomeroy, walked into the camp in late September of 1894 and walked back out four days later alone, having found it empty. The tools were still in the shed.

The cook’s pots were still on the stove. Hennefield’s desk was still standing in his cabin. Pomeroy found in the drawer a folded square of birch bark with a symbol scratched on the inner surface. He did not know what it meant.

He took it with him. He locked up the camp. He filed his report. He went home.

He died of a heart attack the following March at the age of 48, in good health, with no warning. His widow, going through his effects, found the birch bark in the bottom drawer of his bureau and, not knowing what it was, threw it into the fire. The second foreman, a man named Roderick Van Leaf, was sent in the spring of 1895. He walked into the camp, looked around, walked back out, and refused to take the assignment.

He told the company in writing that the camp could not be worked because no man would work it. He was fired for insubordination. He went on to run a successful small farm in Iowa and lived to 91. The third foreman, in 1897, was a man named Ezard Holcomb.

He walked into the camp with 12 new men, set up operations, and began cutting in the southern half of the lease. He stayed away from the northern stand. He sent regular reports. He did good work.

The company was satisfied. In late August of 1897, Ezard Holcomb’s reports stopped. A relief party was sent. They reached the camp on the 2nd of September.

The camp was empty. The horses were in the stable, alive, watered, fed, the relief party noted, perhaps that very morning. The cook’s pots were on the stove. Supper was in them, half eaten.

There were 13 plates set on the long table, 13 forks, 13 knives, 13 tin cups. The food was still warm. There were no men. There were no signs of struggle, no blood, no marks.

The bunkhouse was orderly. The men’s belongings were folded and stacked at the foot of each bed. Their boots were paired neatly. Their jackets hung on the wall hooks.

One man had been writing a letter home, and the letter was on the small table by his bunk, the pen lying across it mid-sentence. The relief party leader, a man named Dewitt Sarvis, copied the unfinished sentence into his own report. It read, “I think tomorrow I will tell Holcomb I want to go back to the village because last night I heard. ” The pen had not been put down.

It had been set down. The cap was on the table beside it, still off. The only other thing that was wrong, the relief party reported, was that the door of the cook shack, which opened to the north toward the lake path, was standing open, even though the wind that day was from the north and would have been blowing it shut. Something had been holding it open.

The relief party could not determine what. They searched the woods for three days. They found nothing. In a footnote of their final document they reported that on the second night of the search, while camped about three quarters of a mile south of the abandoned camp, two of the four men became simultaneously convinced they could hear someone humming.

Not nearby. Far off, from the direction of the lake. They woke the other two men. The other two could not hear it.

After about ten minutes, the two who could hear it could no longer hear it either. Sarvis wrote, very dryly, in the report, “This was attributed to nervous exhaustion. We did not investigate. ”

Voss and Halliburton wrote off the lease in the spring of 1898 and never logged that part of Michigan again.

The land was eventually sold to the federal government and is today part of a national forest. There is a hiking trail that passes within about two miles of where the camp used to be. The trail does not go all the way north, because the trail planners in 1961 surveyed the area and determined the ground there was too unstable for foot traffic. The survey report is a public document.

It does not mention pressed oval or leaning trees. It says only that the soil shows unusual depressive patterns and that the local indigenous community has requested that the area not be developed for recreational use. The request was honored. Lazarus Quincy walked out of the woods with the others on the 16th of August 1894 and went home to a small Cree settlement north of Sault Ste.

Marie. He stopped humming eventually. Otho Renquist, who corresponded with him for a few years, said the humming faded over the course of about six months until it was gone. Lazarus lived another 47 years.

He married. He had a long, quiet life as a guide and trapper. He never talked about what had happened in the woods that summer. But on the night he died in 1941, at the age of 75, his oldest son was sitting with him, and Lazarus, who had been unconscious for most of the day, opened his eyes one last time, looked at his son, smiled, and hummed very softly, four notes of a tune.

His son did not recognize it. Lazarus hummed the four notes twice, closed his eyes, and died. His son told that story only once, to a folklorist in 1968. The folklorist asked him to hum the four notes.

The son refused. He said, “I have not hummed those four notes since the night my father died and I do not intend to hum them again. I do not know what they mean, but I know that they mean something and I have lived a happy life and I do not wish to open a door I do not know how to close. ”

In the summer of 1973, a Forest Service ranger named Hollis Gretzwell, 26 years old, was hiking off trail alone in the area of the old Voss and Halliburton lease.

He found the camp: the foundation stones of the bunkhouse, the rusted remains of two saw blades, a handful of square nails, a piece of a tin cup. He took photographs. He noted the location. He also reported in his official log that as he was leaving, walking south back toward his vehicle, he became aware that he was, without thinking about it, humming.

He did not know the tune. He could not, when asked later, reproduce it. He had tried several times to hum it again the next day and the day after, and he could not. The tune had left him when he reached his vehicle, or, he said, he had left the tune.

He could not say which. Gretzwell retired from the Forest Service in 2004 and still lives in the Upper Peninsula. He gave one interview to a local historian in 2011, at the age of 64. The historian asked him, near the end of the interview, whether he believed that something had happened in those woods in 1894.

He thought about it for a long time before answering. He said, “I believe that whatever the elder warned them about was real. I believe that it is still up there. I believe that the only reason it has not done more harm than it has done is that the people who know about it, the elders, the old families, and now a few of us in the service, have agreed without ever sitting down to agree to leave it alone.

I believe that the door the elder spoke of is still ajar, not open, not closed, ajar. I believe that as long as no one walks up that path with a saw or a camera or a recorder or a young man’s curiosity, it will stay ajar and no further. I believe that if anyone ever does walk up that path again with the wrong intent, the door will open the rest of the way and we will lose more than a logging crew. That is what I believe.

I do not say it often. I am saying it to you now because I am old and because I would rather have said it once on the record than die having said it never. ”

His voice is steady throughout the recording, except in one place near the end, when he says the words, “The door is still ajar. ” In that place, his voice catches, just once.

And in the silence after his voice catches, very faintly, in the background behind the hum of the kitchen refrigerator and the tick of a wall clock, you can hear, if you turn the volume up, four notes. Four notes hummed, very softly, by no one. The historian did not notice the four notes when she made the recording. She only noticed them 15 years later, when she went back to listen to the tape one last time before donating it to the archive.

She noticed them. She turned the recording off. She put the tape into the archive box. She has not played it again.

The archivist who let a researcher hear the tape warned him, in a flat and tired voice, that he did not personally believe there was anything on it, and that he had played it for, at that point, 14 separate researchers, of whom 11 had heard the four notes and three had not. He himself, he said, had heard the four notes the first time and had never heard them again on any of the subsequent listens. He did not know why. The elder had sat in a foreman’s chair on the 3rd of August in 1894 and said in good and careful English, “The word is a kind of door and I will not say it now here near your camp because the door is easier to open than to close.

” He was speaking of one in the woods of Michigan in the late summer of 1894. Some doors, he said, are easier to open than to close.
