To quickly assess the difficulty of the text, read a short excerpt:
It has already been shown that the region has been gnidually elevated during recent geological time. The coastal-plain ten-aces, like the high benches already described, arc made up of material that was deposited along the margin of the shore while the land stood at lower elevation relative to the sea than it does now. The successive benches ECONOMIC GEOLOGY. 81 mark a series of interruptions in the uplift, when the land stood .at a constant elevation long enough to permit th(» aecunuihition of... the material of which the terraces are formed. The sediments of the coastal plain are predominatingly of line mate- rial, usually sand and sandy clay, with some coarser gi-avel layers, and frequent beds of clay. Broadly speaking, these sediments increase in coarseness in an inland direction. They wn»re contributed hy the streams and rivers, which gnidually built out their deltas. These coastiil -plain de]K)sits were laid down on a rock surface which had been more or less channeled by streams and which must have })een very uneven, and the consequence is that there is probably great variation in their thickness.
