My love admits no qualifying dross. - William Shakespeare
The scholar only knows how dear these silent, yet eloquent, companions of pure thoughts and innocent hours become in the season of adversity. When all that is worldly turns to dross around us, these only retain their steady value. - Washington Irving
When through fiery trials thy pathways shall lie,My grace, all sufficient, shall be thy supply;The flame shall not hurt thee; I only designThy dross to consume, and thy gold to refine. - John Rippon
