Key Marco
Key Marco was an archaeological site ( 8CR48) consisting of a large shell works island next to Marco Island, Florida. A small pond on Key Marco, now known as the "Court of the Pile Dwellers" (8CR49),8CR48 designates the entire Key Marco site, while 8CR49 designates just the pond known at the "Court of the Pile Dwellers" within the Key Marco site.(Widmer:2000:ix) was excavated in 1896 by the Smithsonian Institution's Pepper-Hearst Expedition, led by Frank Hamilton Cushing. Cushing recovered more than 1,000 wooden artifacts from the pond, the largest number of wooden artifacts from any prehistoric archaeological site in the eastern United States. These artifacts are described as some of the finest prehistoric Native American art in North America. The Key Marco materials are principally divided between the University of Pennsylvania Museum of Archaeology and Anthropology, University of Pennsylvania; the Department of Anthropology, National Museum of Natural History, Smithson ...

National Museum Of Natural History
The National Museum of Natural History is a natural history museum administered by the Smithsonian Institution, located on the National Mall in Washington, D.C., United States. It has free admission and is open 364 days a year. In 2021, with 7.1 million visitors, it was the eighteenth most visited museum in the world and the second most visited natural history museum in the world after the Natural History Museum in London."The World's most popular museums", CNN.com, 22 June 2017. Opened in 1910, the museum on the National Mall was one of the first Smithsonian buildings constructed exclusively to hold the national collections and research facilities. The main building has an overall area of with of exhibition and public space and houses over 1,000 employees. The museum's collections contain over 145 million specimens of plants, animals, fossils, minerals, rocks, meteorites, human remains, and human cultural artifacts, the largest natural history collection in the world.

Catgut
Catgut (also known as gut) is a type of cord that is prepared from the natural fiber found in the walls of animal Gut (anatomy), intestines. Catgut makers usually use sheep or goat intestines, but occasionally use the intestines of cattle, Domestic pig, hogs, horses, mules, or donkeys. Despite the name, catgut is not made from cat intestines. Etymology The word ''catgut'' may have been an abbreviation of the word "cattlegut". Alternatively, it may derive by folk etymology from ''kitgut'' or ''kitstring'' — the dialectal word ''kit'', meaning fiddle, having at some point been confused with the word ''kit'' for a young cat, the word "kit" being possibly derived from Welsh language, Welsh. Common uses Stringed instruments For a long time, catgut was the most common material for the strings (music), strings of harps, lutes, violins, violas, cellos, and double basses, acoustic guitars and other String instrument, stringed musical instruments, as well as older marching snare drums. ...

Rawhide (textile)
Rawhide is a hide or animal skin that has not been exposed to tanning. It is similar to parchment, much lighter in color than leather made by traditional vegetable tanning. Rawhide is more susceptible to water than leather, and it quickly softens and stretches if left wet unless well waterproofed. "Rawhide" laces often sold for boots or baseball gloves are made of normal tanned leather rather than actual rawhide. Rawhide is not pliable when dry and would be unsuitable for that use. Process The skin from buffalo, deer, elk or cattle from which most rawhide originates is prepared by removing all fur, meat and fat. The hide is then usually stretched over a frame before being dried. The resulting material is hard and translucent. It can be shaped by rewetting and forming before being allowed to thoroughly re-dry. It can be rendered more pliable by 'working', i.e. bending repeatedly in multiple directions, often by rubbing it over a post, sometimes traditionally by chewing. It may ...

Natural Gum
Natural gums are polysaccharides of natural origin, capable of causing a large increase in a solution's viscosity, even at small concentrations. They are mostly botanical gums, found in the woody elements of plants or in seed coatings. Human uses They are used in the food industry as thickening agents, gelling agents, emulsifying agents, and stabilizers, and in other industrial adhesives, binding agents, crystal inhibitors, clarifying agents, encapsulating agents, flocculating agents, swelling agents, foam stabilizers, etc. When consumed by humans, many of these gums are fermented by the microbes that inhabit the lower gastrointestinal tract (microbiome) and may influence the ecology and functions of these microscopic communities. Examples Natural gums can be classified according to their origin. They can also be classified as uncharged or ionic polymers (polyelectrolytes). Examples include (with E number E numbers ("E" stands for "Europe") are codes for substances used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acre
The acre is a unit of land area used in the imperial Imperial is that which relates to an empire, emperor, or imperialism. Imperial or The Imperial may also refer to: Places United States * Imperial, California * Imperial, Missouri * Imperial, Nebraska * Imperial, Pennsylvania * Imperial, Texa ... and United States customary units#Units of area, US customary systems. It is traditionally defined as the area of one Chain (unit), chain by one furlong (66 by 660 feet), which is exactly equal to 10 square chains, of a square mile, 4,840 square yards, or 43,560 square feet, and approximately 4,047 m2, or about 40% of a hectare. Based upon the International yard and pound, international yard and pound agreement of 1959, an acre may be declared as exactly 4,046.8564224 square metres.

Pond
A pond is an area filled with water, either natural or artificial, that is smaller than a lake. Defining them to be less than in area, less than deep, and with less than 30% emergent vegetation helps in distinguishing their ecology from that of lakes and wetlands.Clegg, J. (1986). Observer's Book of Pond Life. Frederick Warne, London Ponds can be created by a wide variety of natural processes (e.g. on floodplains as cutoff river channels, by glacial processes, by peatland formation, in coastal dune systems, by beavers), or they can simply be isolated depressions (such as a kettle hole, vernal pool, prairie pothole, or simply natural undulations in undrained land) filled by runoff, groundwater, or precipitation, or all three of these. They can be further divided into four zones: vegetation zone, open water, bottom mud and surface film. The size and depth of ponds often varies greatly with the time of year; many ponds are produced by spring flooding from rivers. Ponds may be ...

Muck (soil)
A sapric is a subtype of a histosol where virtually all of the organic material has undergone sufficient decomposition to prevent the identification of plant parts. Muck is a sapric soil that is naturally waterlogged or is artificially drained. Classification The soils are deep, dark colored, and friable, often underlain by marl, or marly clay. World Reference Base The World Reference Base for Soil Resources (WRB) defines "sapric" (sa) as a histosol having less than one-sixth (by volume) of the organic material consisting of recognizable plant tissue within 100 cm of the soil surface. Canada Muck soils fall under the Organic Order in the Canadian system of soil classification. Muck soils are organic soils, with at minimum of 30% organic matter and a depth of at least 40 cm. United States In the USDA soil taxonomy, sapric may be a subtype of a haplohemist or glacistel type, and may also be a diagnostic organic soil material where the fiber content is less than one-sixth of ...

Pile Dwelling
Stilt houses (also called pile dwellings or lake dwellings) are houses raised on stilts (or piles) over the surface of the soil or a body of water. Stilt houses are built primarily as a protection against flooding; they also keep out vermin. The shady space under the house can be used for work or storage. Arctic Houses where permafrost is present, in the Arctic, are built on stilts to keep permafrost under them from melting. Permafrost can be up to 70% water. While frozen, it provides a stable foundation. However, if heat radiating from the bottom of a home melts the permafrost, the home goes out of level and starts sinking into the ground. Other means of keeping the permafrost from melting are available, but raising the home off the ground on stilts is one of the most effective ways. Indo-Pacific Raised rectangular houses are one of the cultural hallmarks of the Austronesian peoples and are found throughout the regions in Island Southeast Asia, Island Melanesia, Micronesi ...
