Famous quotes containing the words aquarium and/or trade:
“The Aquarium is gone. Everywhere,
giant finned cars nose forward like fish;
a savage servility
slides by on grease.”
—Robert Lowell (1917–1977)
“Conversation is a traffick; and if you enter into it, without some stock of knowledge, to ballance the account perpetually betwixt you,—the trade drops at once: and this is the reason ... why travellers have so little [good] conversation with natives,—owing to their [the natives’] suspicion ... that there is nothing to be extracted from the conversation ... worth the trouble of their bad language.”
—Laurence Sterne (1713–1768)
