Century Dictionary and Cyclopedia

1. n. Water-worn detritus, finer than that to which the name gravel would ordinarily be applied: but the line between sand and gravel cannot be distinctly drawn, and they frequently occur intermingled. Sand consists usually of the debris of crystalline rocks, and quartz very commonly predominates in it, since this mineral is very little liable to chemical change or decomposition. In regions of exclusively calcareous rocks there is rarely any considerable amount of what can be properly called sand, finely comminuted calcareous materials being extremely liable to become reconsolidated. Sand occurs in every stage of wear, from that in which the particles have sharp edges, showing that they have been derived from the recent breaking up of granitic and other silicious rocks, to that in which the fragments are thoroughly rounded, showing that they have been rubbed against one another during a great length of time. Sand, when consolidated by pressure or held together by some cement, becomes sandstone; and a large part of the material forming the series of stratified rocks is sandstone.
2. n. A tract or region composed principally of sand, like the deserts of Arabia; or a tract of sand exposed by the ebb of the tide: as, the Libyan Sands; the Solway sands.
3. n. Any mass of small hard particles: as, the sand of an hour-glass; sand used in blotting.
4. n. In founding, a mixture of sand, clay, and other materials used in making molds for casting metals. It is distinguished according to different qualities, etc., and is therefore known by specific names: as, core-sand, green sand, old sand, etc.
5. n. Sandstone: so used in the Pennsylvania petroleum region, where the various beds of petroliferous sandstone are called oil-sands, and designated as first, second, third, etc., in the order in which they are struck in the borings. Similarly, the gas-bearing sandstones are called gas-sands.
6. n. plural The moments, minutes, or small portions of time; lifetime; allotted period of life: in allusion to the sand in the hour-glass used for measuring time.
7. n. Force of character; stamina; grit; endurance; pluck.
8. To sprinkle with sand; specifically, to powder with sand, as a freshly painted surface in order to make it resemble stone, or fresh writing to keep it from blotting.
9. To add sand to: as, to sand sugar.
10. To drive upon a sand-bank.
11. n. A message; a mission; an embassy.
