Famous quotes containing the word table:
“The newspaper is a Bible which we read every morning and every afternoon, standing and sitting, riding and walking. It is a Bible which every man carries in his pocket, which lies on every table and counter, and which the mail, and thousands of missionaries, are continually dispersing. It is, in short, the only book which America has printed, and which America reads. So wide is its influence.”
—Henry David Thoreau (1817–1862)
“When the painted birds laugh in the shade,
When our table with cherries and nuts is spread:
Come live, and be merry, and join with me
To sing the sweet chorus of ‘Ha, ha, he!’”
—William Blake (1757–1827)
