that after those strata were formed, violent and sudden upheavals took place, throwing them into new positions, then slow uprisings of the bottom of the sea, or slow subsidings of the land. At one time the northern parts of Europe and America were covered with ice. Great glaciers extended over the whole of Switzerland, and icebergs floated from the mountains of Berkshire in Massachusetts upon a sea which filled the valley of the Connecticut River, dropping erratic blocks of stone, taken from those mountains, in straight lines, parallel with each other, half way across the valley, where they still lie. Similar icebergs floated from Snowdon, in Wales, and Ben Lomond, in Scotland, over the submerged islands of Great Britain. At one time the whole surface of the earth, instead of being covered with icy glaciers, was filled with a hot, damp atmosphere, laden with carbonic gas, which no creature could breathe, but in which grew great forests of a strange tropical vegetation. Then came another period, in which all these forests were submerged and buried, and at last turned into coal. Long after this hot period had passed, and long after the cold, glacial period, which followed it, had departed, came a time when the elephant, the rhinoceros, and the hippopotamus covered the whole of Europe, and the mammoth roamed in North America. Such facts as these, incontestably established by the amplest evidence, have made it impossible for any reasonable man to believe that the earth was made in six days, or that it was made only six thousand years ago. But this question being thus disposed of, other questions arise in their turn. Are all mankind descended from one pair, or from many? Has the human race existed on the earth only six thousand years, or during a longer period? Was the deluge of Noah a real event? and if so, was it universal or partial? Did the sun stand still at the command of Joshua? or is that only a poetic image taken from an ancient book of poems—the book of Jasher? Is there any truth in the story of the passage of the Red Sea by the Israelites? of the passage of the Jordan? of the walls of Jericho falling when the trumpets were blown? of the story of Samson? If we once begin to doubt and disbelieve the accounts in the Bible, where shall we stop? What rule shall we have by which to distinguish the true from the false? Is it safe to begin to question and deny? Is it not safer to accept the whole book as the word of God, and to let everything in it stand unexamined?
