Wherever the standard of freedom and independence has been or shall be unfurled, there will her heart, her benedictions and her prayers be. But she goes not abroad in search of monsters to destroy.

She will recommend the general cause, by the countenance of her voice, and the benignant sympathy of her example. - John Quincy Adams
