From the Aurora Beacon 09/26/1907:
Michigan Bovine Crazed By Her Imprisonment
Literally reduced to a skeleton, a cow was found near Ewen, Michigan, firmly anchored to a tree, in the crotch of which her tail had become fastened. The animal is believed to have spent upward of a month in the area of a few square feet that proved her prison, subsisting without water and with only one day’s supply of food.
The cow is owned by Joseph Blake of Greenland, Ontonagon County. She had been missing for five weeks when a man passing through the woods accidentally found her in the situation described.
Crazed from starvation, the sight of the man apparently infuriated the animal. She broke loose from the tree, leaving her tail behind, and charged her would be rescuer. He sought safety on a woodpile, and was kept there for three-quarters of an hour, when the cow left to seek food.
