The wanton Maidens him espying, stood
2 Gazing a while at his vnwonted guise;
Then th'one her selfe low ducked in the flood,
4 Abasht, that her a straunger did a vise:
But th'other rather higher did arise,
6 And her two lilly paps aloft displayd,
And all, that might his melting hart entise
8 To her delights, she vnto him bewrayd:
The rest hid vnderneath, him more desirous made.
