Famous quotes containing the words ground and/or glass:

    “Nor must Uncle Sam’s Web-feet be forgotten. At all the watery margins they have been present. Not only on the deep sea, the broad bay, and the rapid river, but also up the narrow muddy bayou, and wherever the ground was a little damp, they have been, and made their tracks.”
    —Abraham Lincoln (1809–1865)

    “The glass has been falling all the afternoon”
