Famous quotes containing the words plates and/or printing:

    I have experienced such simple delight in the trivial matters of fishing and sporting, formerly, as might have inspired the muse of Homer or Shakespeare; and now, when I turn the pages and ponder the plates of the Angler’s Souvenir, I am fain to exclaim,—

    And overcome us like a summer’s cloud?”
