Some scientists reason that the Falls of Niagara must have been formed soon after the Glacial Epoch, and the time occupied in wearing the rock back to the present position therefore furnishes a basis for calculating the age of man on the earth, as he must have begun his career since that epoch:
In an address in Washington before the United States Geological Survey, Professor Gilbert gave the following interesting information regarding the recession of the ground under Niagara Falls: The estimate is that for the past forty-four years the falls have receded at the rate of twenty-four feet in a year. The Horseshoe Falls are at the head of the gorge and the American Falls at the eastern side, but the time was when both were together, before the little point called Goat Island was reached. The recession is more rapid at the center than on the sides. As the crest of the Horseshoe Falls retreats the water tends to concentrate there, and the time will probably come when the sides of the present falls will have become dry shores. The gorge is known to be 35,500 feet long. A calculation has shown that, on this basis, the falls began to wear away the rock of the escarpment near Lewiston about 7,900 years ago.—Public Opinion.

MAN’S CONQUEST OF ANIMALS
Man-eating tigers have for so long been regarded by the natives of most parts of India as invincible, or else protected by the native religions, that they have had things pretty much their own way. One determined hunter for every fifty frightened, unarmed men would scarcely serve to intimidate any animal. Many tribes of North American Indians looked upon the bear with veneration; but for all that, any bear so courageous as to let himself be seen by them got an arrow between his ribs right away, and in time the whole tribe of American bears learned that the chances were against them, just as the wolves and cougars arrived at a similar conclusion. Those that turned man-eaters might for a few seasons hunt their prey successfully, and if gifted with unusual cunning get away unscratched for a while, but the vengeance of the tribe would be certain to overtake them before very long, and only the more cowardly ones of their species would survive to perpetuate the race.—Witmer Stone and William Everett Cram, “American Animals.”

Man’s Greatness—See [Size not Power].
MAN’S IMPORTANCE
The world is one thing to a bird, or a fish, but quite another thing to Cuvier or Agassiz. Then man entered the scene. Stretching out his hand he waved a wonder-working wand. He touched the wood, and it became a wagon; he touched the ore and it became an engine; he touched the boughs and they became the reeds of an organ; he touched the wild animal, and it became a burden-bearer for his weary feet; while his intellect turned the stone into geology, and the stars into astronomy, and the fields into husbandry, and his duties into ethics. When the flint and steel meet, something beyond either appears—a tongue of flame. And when man and nature met, something new emerged—art, industry, ethics, cities and civilization. There is nothing great in nature but man. Take man out of this wondrous city with its cathedrals, galleries, and homes, and Broadway would become a streak of iron-rust. The earth wears man upon her bosom as the circling ring wears a sparkling gem. The bog puts forth a white lily; genius is a flower rooted in earth, but borrowing its bloom and beauty from heaven.—N. D. Hillis.
