The Speaker
The speaker in “Anecdote of the Jar” does an experiment using a jar. This speaker reminiscences about a jar he put on a hill in Tennessee. The speaker does not give the impetus of the experimentation, but recapitulates the outcomes.
The Jar
The jar is an inanimate character that is placed on a hill. After being set on hill, the jar prompted the wilderness to circumscribe the hill. The jar is fascinating and existent; such an item specifies that the poem is about a perceptible object.
