Smoke continues to pour out of what's left of a barn near Mosinee after it went up in flames twice.

The barn at 797 Chestnut Road in the Town of Knowlton caught fire at about 7p.m. Tuesday night and re-ignited hours later.

According to the Chief of the Mosinee Fire District, Bruce Rheinschmidt, they battled the blaze for several hours and received mutual aid from the Kronenwetter Fire Department.

Chief Rheinschmidt says crews returned to the scene to apply a coat of foam material after the hay and wooden beams re-ignited between 2 and 3 Wednesday morning.

He says investigators say the blaze may have been sparked by two electrical tank heaters in the barn.

Chief Rheinschmidt says the home owner plugged them in to keep their animals water from freezing.

The chief says fire crews used at least 40- thousand gallons of water fighting the fire, hoping to save the structure.

"When we got there about 2/3 of the barn was already gone. The roof was in, the two sides had collapsed and there wasn't much left to save, " says Chief Rheinschmidt.

Frances Wauters lives on the farm with her fiance Jake Holguin.

Wauters says no one was hurt in the fire but they are still looking for one of their cattle.

She says the blaze cost them some new equipment.

"We had a brand new tractor all of our equipment for our hay field so we could feed our animals instead of buying it."

In addition to the farming equipment and tools they lost most of the feed for their 21 head of cattle and 2 horses, saying now they won't have enough food to feed their animals for the rest of the winter.

Wauters says they did have insurance but it won't cover everything they lost including a lot of memories.

She says the farm is about 100 years old and Jake's Grandfather actually built the barn and the surrounding sheds.

"He had told me that his Grandfather used to throw 80lb barrels of hay over the beams of the floor of the barn...the buildings may be gone but the memories are still there, " says Wauters.
