Sand, George, pseud. of Amandine Aurore Lucie Dupin, baronne Dudevant, 1804-76, French novelist. Other variant forms of her maiden name include Amantine Lucile Aurore Dupin. Born of an aristocratic father and a lower-class mother, she was reared by her austere paternal grandmother on a country estate in Berry. After entering a convent in Paris, she returned to the countryside and led an unconventional life, donning the male clothes that became a mark of her rebellion. In 1831, after eight years of a marriage of convenience with Baron Dudevant, a country squire, she went with her two children to Paris, obtaining a divorce in 1836. She wrote some 80 novels, which were widely popular in their day, supporting herself and her children chiefly by her writing. Her earlier novels were romantic; later ones often expressed her serious concern with social reform. Her liaisons—with Jules Sandeau, Musset, Chopin, and others—were open and notorious, but were only part of her life. She demanded for women the freedom in living that was a matter of course to the men of her day.

Her first novel, Rose et Blanche (1831), was in collaboration with Jules Sandeau (a shortening of his last name provided her with the pseudonym which she kept all her life), with whom she had previously written articles for the journal Figaro. Of her own novels, La Mare au diable (1846, tr. The Haunted Pool, 1890) and Les Maǐtres sonneurs [the master bell-ringers] (1853) are considered masterpieces. Notable also are Indiana (1832, tr. 1881), Mauprat (1837), Consuelo (1843, tr. 1846), François le champi (1848, tr. Francis the Waif, 1889), La Petite Fadette (1849, tr. Fanchon the Cricket, 1864), and Contes d'une grand'mère (1873, tr. Tales of a Grandmother, 1930), a collection of Breton fairy tales. All these books are distinguished by a romantic love of nature as well as an extravagant moral idealism. She also wrote a number of plays. Much of her work was autobiographical, notably Histoire de ma vie (1854); Elle et lui [she and he] (1859), which concerns her life with Musset; and Un Hiver à Majorque [a winter in Majorca] (1842), about her life with Chopin.

sand, rock material occurring in the form of loose, rounded or angular grains, varying in size from .06 mm to 2 mm in diameter, the particles being smaller than those of gravel and larger than those of silt or clay. Sand is formed as a result of the weathering and decomposition of igneous, sedimentary, or metamorphic rocks. Its most abundant mineral constituent is silica, usually in the form of quartz, and many deposits are composed almost exclusively of quartz grains. Many other minerals, however, are often present in small quantities, e.g., the amphiboles, the pyroxenes, olivine, glauconite, clay, the feldspars, the micas, iron compounds, zircon, garnet, tourmaline, titanite, corundum, and topaz. Some sands—e.g., coral sands, shell sands, and foraminiferal sands—are organic in origin. Sand grains may be rounded or more or less angular, and differences in shape and size account chiefly for differences in such important properties as porosity (proportion of interstices to the total mass), permeability to gases and liquids, and viscosity, or resistance to flow. Permeability and viscosity are also affected by the proportion of clayey matter present. The chief agents in accumulating sands into deposits are winds, rivers, waves, and glaciers; sand deposits are classified according to origin as fluviatile, lacustrine, glacial, marine, and eolian. The most extensive superficial deposits are seen in the desert and on beaches. The surface of a sand deposit may be level or very gently sloping, or the sand may be gathered by wind action into ridges called dunes. Sandstone and quartzite rocks are indurated masses of sand, and sand deposits are sometimes formed by the weathering of sandstone and quartzite formations. Sand is used extensively in the manufacture of bricks, mortar, cement, concrete, plasters, paving materials, and refractory materials. It is also used in the metallurgical industry, in the filtration of water, in pottery making, in glassmaking, in the manufacture of explosives, and as an abrasive. Other industrial uses are numerous. Although soils entirely composed of sand are too dry and too lacking in nourishment for the growth of plants, a soil that is to some extent sandy (a "light" soil) is favorable to certain types of agriculture and horticulture, as it permits the free movement of air in the soil, offers less resistance than a clay soil to growing roots, improves drainage, and increases ease of cultivation. Sand to which nutrient solutions have been added is often used in soilless gardening.
Sand is the site of a major archaeological excavation on the Inner Sound coast of the Applecross Peninsula in Western Scotland, to the north of the small town of Applecross.

A small number of shell middens were known as rare traces of Mesolithic settlement when a rock shelter and shell midden at Sand, Applecross on the coast of Wester Ross, Scotland was selected for detailed excavation as part of a study of shell middens in the area around the Inner Sound between Skye and the mainland.

The Scotland’s First Settlers project (SFS) investigating the relationship of early inhabitants with the western seaboard chose this area which had known sites at An Corran in Staffin, Skye and at Redpoint and Shieldaig in Torridon. Their surveys in 1999 and 2000 found 104 previously unknown sites, mostly caves and rock shelters with 21 "lithic scatters" and 9 open shell middens. A proportion of these sites will be more recent, but test pits at 4 sites found Loch a Sguirr on Raasay and Sand in Applecross to be Mesolithic. The indication is that there are many more surviving sites than had been expected.

The rock shelter site at Sand on the Applecross peninsula, just to the north of Applecross itself, faces out across the Inner Sound westwards towards Skye and Raasay. Around 7500 BC the first users of the rock shelter had worked antler and stone to make tools. As well as using local stone for their tools they had obtained distinctive stone from the island of Rùm, 30 km (19 miles) to the south, and Staffin on Skye, 10 km (6 miles) to the west, showing that they were able to cross open sea.

Gradually a large pile of shells, mainly limpets, built up into a large midden. Abundant fragments of stone "pot-boilers" and bevel ended bone tools indicate that the shellfish were being cooked and the contents scooped out. There were also bones from red deer and birds and an antler harpoon for catching a wide range of fish, including cod, mackerel, haddock, herring and salmon.

Fine beads had been made from seashells, while ochre pigment and a particular species of dog whelk that may have been used for the extraction of purple dye suggest concern with decoration.
