From Montana

An old rancher’s solution:
The huge suspended boulder keeps this barbed wire fencing taut.
It compensates for changes in temperature, and insistent cows.
From Maryland

Found in a friend’s attic. Marked Hickok.
The Rochester New York based manufacturer Hickok sold belts from the 1930’s to the 1950’s, and packaged some of them in these plastic boxes.
The owner was the great nephew of Wild Bill Hickok.
