A poem as transparent as glass

I prefer to read poems that are transparent, that don't require me to strain my brain to decipher the poem's meaning. An example of such a poem is Roger Heston.

Roger Heston by Edgar Lee Masters

Oh many times did Ernest Hyde and I
Argue about the freedom of the will.
My favorite metaphor was Prickett's cow
Roped out to grass, and free you know as far
As the length of the rope.
One day while arguing so, watching the cow
Pull at the rope to get beyond the circle
Which she had eaten bare,
Out came the stake, and tossing up her head,
She ran for us.
"What's that, free-will or what?" said Ernest, running.
I fell just as she gored me to my death.

After reading the poem, I wondered whether a cow can have horns. I've seen many cows and can't remember any having horns, especially ones sufficiently large to gore someone to death. However, a Google search informed me that I was wrong. In several cattle breeds the females have horns, including the Texas Longhorn. On the other hand, in some cattle breeds not even the bulls have horns. One such breed is the Angus. And even if you see a hornless cow, it doesn't mean that its horns haven't been removed. Horns can be dangerous both to other cattle and to humans, as the speaker in Masters' poem discovered.

Masters concluded his poem with a twist. Its final line states that "I fell just as she gored me to my death." Yet, after his unfortunate demise, the speaker was able to share, in writing, how he met his end. A miraculous ending to an excellent poem.
