Geol. Note the remarkable absence of limestone among the drift. Most of drift-rocks seem to have been derived from lower Series (#4.3.2.1.) Near the Mts limestone quite common in gravel of creeks &c scarcely a fragment on the plains. As the limestone is mostly confined to the central & highest parts of the range, & the lower beds above mentioned seem generally to form the outer & lower tier of mountains. It would seem that no glaciers of any consequence could have been descending at time of greatest & last submergence. That gravel probably distributed by coast ice, & that water at deepest did not rise high up on the mountains proper though overtopping the foot hills.
