Artesian Wells differ from ordinary wells in that their waters are discharged by natural pressures on their reservoirs, so that pumping is not necessary to raise the water Such wells are therefore true springs.

"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

"To measure the depth of; fathom; try or test, as the depth of water and the quality of the ground, by sinking a plummet or lead attached to a line on which is marked the number of fathoms...a, lead; b, counterpoised hooks which engage the loop at the top of the lead; d, wedge-shaped cup for specimens, attached by cord or wire to the pivot of the hooks; e, attachment for the sounding-line or wire. When the cup d touches bottom, the hooks b drop into the position show in E; the sinker or lead then drops over, releasing the cup, and this, with its specimen and the hooks, is drawn to the surface." —Whitney, 1889

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.
