Famous quotes containing the word ports:
“I need not tell you of the inadequacy of the American shipping marine on the Pacific Coast.... For this reason it seems to me that there is no subject to which Congress can better devote its attention in the coming session than the passage of a bill which shall encourage our merchant marine in such a way as to establish American lines directly between New York and the eastern ports and South American ports, and both our Pacific Coast ports and the Orient and the Philippines.”
—William Howard Taft (1857–1930)
“All places that the eye of heaven visits
Are to a wise man ports and happy havens.”
—William Shakespeare (1564–1616)
“O polished perturbation! golden care!
That keep’st the ports of slumber open wide
To many a watchful night.”
—William Shakespeare (1564–1616)
