Classic Poem

W HERE'ER you find " the cooling western breeze",
In the next line, it " whispers through the trees";
If crystal streams " with pleasing murmurs creep",
The reader's threatened (not in vain) with " sleep".
Then, at the last and only couplet fraught
With some unmeaning thing they call a thought,
A needless Alexandrine ends the song,
That, like a wounded snake, drags its slow length along.
