The Vedic fathers of geology

84 Tue Vepic FATHERS OF GEOLOGY.

Before concluding, I may with advantage make some obseryations and give opinions of eminent geologists and Savants, in view of giving to the Reader some idea as to the time that has elapsed since the close of the Tertiary Epoch and that of the Glacial Age. According to Dr. Croll, the Glacial Period must have begun 240,000 years before, and ended, followed by the Quaternary or Post-Glacial period, about 80,000 years ago; having lasted for nearly 160,000 years, with alterations of milder and even tropical temperature. ( vide Dr. Croll’s Climate and Time, and Climate and Cosmology ). Many American geologists, however, are of opinion that the close of the last Glacial Epoch must not have taken place at such on earlier date, and assign a period of only 8,000 years to the close of the last Glacial Epoch. But, Professor Geikie and other reputed geologists think otherwise, as they consider that there were five Glacial and four inter-Glacial Epochs, and that the total duration thereof must have extended to about 80,000 years.

Lyell, who had visited the Niagara-falls in 1841, after studying and carefully reconsidering all the data in the matter of investigations, by which geological time could be measured in years, concluded that the time since the close of the
