Analysis of Associations

As o'er these hills I take my silent rounds,
Still on that vision which is flown I dwell,
On images I loved, alas, too well!
Now past, and but remembered like sweet sounds
Of yesterday! Yet in my breast I keep
Such recollections, painful though they seem,
And hours of joy retrace, till from my dream
I start, and find them not; then I could weep
To think how Fortune blights the fairest flowers;
To think how soon life's first endearments fail,
And we are still misled by Hope's smooth tale,
Who, like a flatterer, when the happiest hours
Pass, and when most we call on her to stay,
Will fly, as faithless and as fleet as they!
