and the relation it sustains to our own time noticed and recorded, “The sun to give light by day.” In a similar manner the moon and the stars were all noticed. As vegetation had now arrived at its climax, Moses closed this age, making the cryptogram in the gray twilight the evening, and its contrast the gay flower basking in clear sunlight the morning. “And the evening and the morning were the fourth day.” 7. Gases are combined into rock through the agency of air and water. There are three methods of conveying or changing gas into rock. The first is by gases mingling directly with the water. This gave us the larger portion of sedimentary rock. For aught that science has yet discovered, the entire bed of primary granite was made in this manner. The second is by combining the gases by means of diatoms and polyps of the seas. These animals do not depend upon vegetation, but draw their nourishment directly from the waters. Their remains constitute large portions of sedimentary rock. The marble and chalk are formed almost entirely of their remains, while all sedimentary rock this side the granite contains more or less of their remains. A third way is by gases combining in vegetation. Anthracite coal is ninety-six per cent. carbon, combined through vegetation. 8. It is evident that the days of creation were not given to mark an order of time. (1.) Creation commenced before time. (2.) Without motion there could be no measure of duration. (3.) The fifth day includes all the fourth and part of the third; and could therefore be no order of time. 9. They were not designed to mark an order in the deposit of rock. All stratified rock, from the Gneiss to the Myocene deposit, is included in the fifth day. They do not, therefore, give a progressive order of deposit.
