What is niagara?

Famous quotes containing the word niagara:

“From a drop of water a logician could infer the possibility of an Atlantic or a Niagara without having seen or heard of one or the other.”
—Sir Arthur Conan Doyle (1859–1930)

“We set up a certain aim, and put ourselves of our own will into the power of a certain current. Once having done that, we find ourselves committed to usages and customs which we had not before fully known, but from which we cannot depart without giving up the end which we have chosen. But we have no right, therefore, to claim that we are under the yoke of necessity. We might as well say that the man whom we see struggling vainly in the current of Niagara could not have helped jumping in.”
—Anna C. Brackett (1836–1911)
