Read it through once

But most by numbers judge a poet's song And smooth or rough, with them is right or wrong. In the bright muse though thousand charms conspire, Her voice is all these tuneful fools admire, Who haunt Parnassus but to please their ear, Not mend their minds, as some to church repair, Not for the doctrine but the music there These equal syllables alone require, Though oft the ear the open vowels tire; While expletives their feeble aid do join; And ten low words oft creep in one dull line, While they ring round the same unvaried chimes, With sure returns of still expected rhymes, Where'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 [356] That, like a wounded snake drags its slow length along.
