sourdough starter and a bundle of dried beans.

Once a person proved she was not simply waiting to fail, the prairie’s rules changed a little.

The first snow came in October and vanished two days later.

The second came in November and stayed in the shadows.

By December the land had turned hard and white, and the wind no longer moved around a person so much as through one.

Anna developed a routine as strict as scripture.

She kept the stove fed with twisted hay, dung fuel, and any root or scrap of wood she could spare.

She hung blankets to create a smaller sleeping space at night.

She stuffed every crack with cloth.

She set pans to catch drips when the roof sweated on warm afternoons and patched the outer coat whenever weather gave her an hour.

Fritz fetched snow to melt for water.

Greta learned to sit near the window and shell beans into a bowl without complaint.

There were frightening moments.

Once the chimney clogged with a crust of soot and damp ash, and smoke backed into the room until all three of them were coughing and half blind.

Anna thrust the children outside into the bitter air, climbed onto the roof with frozen fingers, and cleared the pipe while the wind cut through her skirt like knives of ice.

Another time the door nearly iced shut during a blowing storm, and she had to hack at the packed drift with a shovel from inside while Fritz braced against the frame.

Hunger gnawed steadily through January.

The potatoes shrank.

The beans dwindled.

But the walls held, the stove worked, and nobody froze.

As the season deepened, stories about Anna’s house changed shape in town.

At first people had laughed because laughter makes risk easier to watch from a distance.

Then the weather worsened, and no word came of her death.

Men passing through the area reported smoke from her stovepipe after storms that had driven even seasoned settlers indoors.

A circuit preacher stopped by in February and later told the congregation that he had found a cleaner, tidier, more determined household in that little earth room than in many framed houses back east.

By late winter, curiosity had begun to replace mockery.

It was the county assessor’s trip in March that fixed the story in local memory.

The day was bitter and bright, the snow old and crusted, the sky polished blue.

The assessor came out to check improvements on several claims, and half a dozen others accompanied him because there was little else to do and because people wanted to see whether the famous straw shack was truly standing.

Silas Murdoch came too, perhaps hoping for some final embarrassment that might still turn the land his way.

They arrived expecting something pathetic.

What they saw was a snug, half-sheltered dwelling banked into the prairie, its roof sealed, its stovepipe breathing a steady column of smoke, its doorway swept clear.

When Anna opened the door, warmth moved into the cold air in a visible wave.

Inside, the children sat on the bed platform with scrubbed faces and mended clothes.

The dirt floor was hard as plaster.

The walls were smooth where she had coated them with clay.

The shelves held jars, a Bible, a comb, and a
