The stratijied sand and gravel of Nova Scotia rests upon and is newer than tlic unstratilied drift, and is probably also newer than the stratified marine clays above referred to. Its age is probably that of the Saxicava sand. The former relation may often bo seen in coast sections or river banks, and occasionally in road-cuttings. I observed some years ago an instructive illustration of this fact, in a bank on tlie shore a little to the eastward of Mcrigoinish harbour (Fig. 22). At this place the lower part of the bank consists of clay and sand with angular stones, principally sandstones. Upon Fig. 22.—Stratijied Gravel resting on Drift,— this rests a bed of fine sand and small rounded gravel with layers of coarser pebbles. The gravel is separated from the drift below by a layer of the same sort of angular stones that appear in the drift, showing that the currents which deposited the upper bed have washed away some of the finer portions of th
