Famous quotes containing the words comparison and/or tables:
“Clay answered the petition by declaring that while he looked on the institution of slavery as an evil, it was ‘nothing in comparison with the far greater evil which would inevitably flow from a sudden and indiscriminate emancipation.’”
—State of Indiana, U.S. public relief program (1935-1943)
“Moving between the legs of tables and of chairs,
Rising or falling, grasping at kisses and toys,
Advancing boldly, sudden to take alarm,
Retreating to the corner of arm and knee,
Eager to be reassured, taking pleasure
In the fragrant brilliance of the Christmas tree....”
—T.S. (Thomas Stearns)
