Analysis of An Apologue

A traveler observed one day
A loaded fruit-tree by the way.
And reining in his horse exclaimed:
'The man is greatly to be blamed
Who, careless of good morals, leaves
Temptation in the way of thieves.
Now lest some villain pass this way
And by this fruit be led astray
To bag it, I will kindly pack
It snugly in my saddle-sack.'
He did so; then that Salt o' the Earth
Rode on, rejoicing in his worth.
