Geikie says:
"Many geologists can not yet be persuaded that till has ever formed and accumulated under ice." [3]
A recent scientific writer, after summing up all the facts and all the arguments, makes this confession:
[1. "American Cyclopædia," vol. vi, p. 112.
2. "The World before the Deluge," pp. 435, 463.
3. "The Great Ice Age," p. 370.]
{p. 9}
From the foregoing facts, it seems to me that we are justified in concluding:
"1. That however simple and plausible the Lyellian hypothesis may be, or however ingenious the extension or application of it suggested by Dana, it is not sustained by any proof, and the testimony of the rocks seems to be decidedly against it.
"2. Though much may yet be learned from a more extended and careful study of the glacial phenomena of all parts of both hemispheres, the facts already gathered seem to be incompatible with any theory yet advanced which makes the Ice period simply a series of telluric phenomena, and so far strengthens the arguments of those who look to extraneous and cosmical causes for the origin of these phenomena."[1]
