So fast, his lessons lagg’d behind;
She reason’d, without plodding long,
Nor ever gave her judgment wrong. 
But now a sudden change was wrought;
She minds no longer what he taught. 
Cadenus was amazed to find
Such marks of a distracted mind: 
For, though she seem’d to listen more
To all he spoke, than e’er before,
He found her thoughts would absent range,
Yet guess’d not whence could spring the change. 
And first he modestly conjectures
His pupil might be tired with lectures;
Which help’d to mortify his pride,
Yet gave him not the heart to chide: 
But, in a mild dejected strain,
At last he ventured to complain: 
Said, she should be no longer teazed,
Might have her freedom when she pleased;
Was now convinced he acted wrong
To hide her from the world so long,
And in dull studies to engage
One of her tender sex and age;
That every nymph with envy own’d,
How she might shine in the grand monde: 
And every shepherd was undone
To see her cloister’d like a nun. 
This was a visionary scheme: 
He waked, and found it but a dream;
A project far above his skill: 
For nature must be nature still. 
If he were bolder than became
A scholar to a courtly dame,
She might excuse a man of letters;
Thus tutors often treat their better;
And, since his talk offensive grew,
He came to take his last adieu. 
  Vanessa, fill’d with just disdain,
Would still her dignity maintain,
Instructed from her early years
To scorn the art of female tears. 
  Had he employ’d his time so long
To teach her what was right and wrong;
Yet could such notions entertain
That all his lectures were in vain? 
She own’d the wandering of her thoughts;
But he must answer for her faults. 
She well remember’d to her cost,
That all his lessons were not lost. 
Two maxims she could still produce,
And sad experience taught their use;
That virtue, pleased by being shown,
Knows nothing which it dares not own;
Can make us without fear disclose
Our inmost secrets to our foes;
That common forms were not design’d
Directors to a noble mind. 
Now, said the nymph, to let you see
My actions with your rules agree;
That I can vulgar forms despise,
And have no secrets to disguise;
I knew, by what you said and writ,
How dangerous things were men of wit;
You caution’d me against their charms,
But never gave me equal arms;
Your lessons found the weakest part,
Aim’d at the head, but reach’d the heart. 
  Cadenus felt within him rise
Shame, disappointment, guilt, surprise. 
He knew not how to reconcile
Such language with her usual style: 
And yet her words were so exprest,
He could not hope she spoke in jest. 
His thoughts had wholly been confined
To form and cultivate her mind. 
He hardly knew, till he was told,
Whether the nymph were young or old;
