"represents a section of an island, from the ocean (o) to the lagoon (l). On the ocean side, from o to a, there is shallow water for some distance out; and where not too deep, the bottom is covered here and there with growing corals. Between a and b there is a platform of coral rock, mostly bare at low tide, but covered at high ... b to d is the wooded portion of the island. The whole width (is) from the beach (b) to the lagoon (c)." -Dana, 1880

"Where the sea bottom has a very gentle slope, the waves break at some distance from the shore and the sand they carry is deposited, forming a barrier beach (B) along the line of greatest disturbance. The strip of water inclosed between the land and the barrier beach is called a lagoon (L)." -Dryer, 1901

A coastal plain in the first cycle of erosion. The presence of two hard layers produces a terraced cuesta front. In exceptional cases the upper terrace may weather back with sufficient rapidity to constitute a second cuesta with a lowland of some width between it and the lower cuesta, if the weak stratum between the harder is of sufficient thickness.

"Diagram illustrating the gradual filling up of lakes by the encroachment of vegetation, and also the stages in the origin of peat and marl deposits in lakes. The several plant associations of the Bog series, displacing one another, belong to the following major groups: (I) O. W., open water succession; (2) M., marginal succession; (3) S., shore succession; (4) B., bog succession, comprising the bog-meadow (Bm), bog-shrub (Bs) and bog-forest (Bf); and (5) M. F., mesophytic forest succession." -Gager, 1916
