James Fenimore Cooper: The Last of the Mohicans

CHAPTER 3 (continued)

"It can't be denied that your traditions tell you true in both these matters," said the white man; "for I have been there, and have seen them, though why water, which is so sweet in the shade, should become bitter in the sun, is an alteration for which I have never been able to account."

"And the current!" demanded the Indian, who expected his reply with that sort of interest that a man feels in the confirmation of testimony, at which he marvels even while he respects it; "the fathers of Chingachgook have not lied!"

"The holy Bible is not more true, and that is the truest thing in nature. They call this up-stream current the tide, which is a thing soon explained, and clear enough. Six hours the waters run in, and six hours they run out, and the reason is this: when there is higher water in the sea than in the river, they run in until the river gets to be highest, and then it runs out again."

"The waters in the woods, and on the great lakes, run downward until they lie like my hand," said the Indian, stretching the limb horizontally before him, "and then they run no more."

"No honest man will deny it," said the scout, a little nettled at the implied distrust of his explanation of the mystery of the tides; "and I grant that it is true on the small scale, and where the land is level. But everything depends on what scale you look at things. Now, on the small scale, the 'arth is level; but on the large scale it is round. In this manner, pools and ponds, and even the great fresh-water lakes, may be stagnant, as you and I both know they are, having seen them; but when you come to spread water over a great tract, like the sea, where the earth is round, how in reason can the water be quiet? You might as well expect the river to lie still on the brink of those black rocks a mile above us, though your own ears tell you that it is tumbling over them at this very moment."

If unsatisfied by the philosophy of his companion, the Indian was far too dignified to betray his unbelief. He listened like one who was convinced, and resumed his narrative in his former solemn manner.
