River Rivelin
The River Rivelin is a river in Sheffield, South Yorkshire, England. It rises on the Hallam moors, in north west Sheffield, and joins the River Loxley (at Malin Bridge). The Rivelin Valley, through which the river flows, is a -mile-long woodland valley which includes the popular Rivelin Valley Nature Trail that was created in 1967. The valley has farmland on its gentler upper slopes. Tributaries include the Wyming Brook, Allen Sike and the Black Brook. The Rivelin Dams are to be found at the head of the valley. A relatively fast-flowing river (it drops 80 metres between Rivelin Mill Bridge and Malin Bridge), the Rivelin is fed by a constant release of water from the nearby moorland peat. Its flow was exploited for centuries as a power source, driving the water wheels of up to twenty industries (forges, metal-working and flour mills) along its course. History Roman times There is evidence of Roman occupation of the area which comes from tablets found in April 1761 on the Stan ...

Common Darter
The common darter (''Sympetrum striolatum'') is a dragonfly of the family Libellulidae native to Eurasia. It is one of the most common dragonflies in Europe, occurring in a wide variety of water bodies, though with a preference for breeding in still water such as ponds and lakes. In the south of its range adults are on the wing all year round. Appearance ''Sympetrum'' species are not easy to tell apart and in most areas more than one ''Sympetrum'' species will occur. Females and teneral individuals have light yellow thorax and abdomen. Males turn red as they mature. Females darken with age, becoming a dark chocolate brown, and sometimes develop a blue colouration to the bottom of the abdomen. The wings also develop a brown tinge with age. In all cases the legs have a cream or yellow stripe on a black background - this is a diagnostic feature of this species. The pterostigma of the females can be red, blue, pale blue or brown.

Gretna Green
Gretna Green is a parish in the southern council area of Dumfries and Galloway, Scotland, on the Scottish side of the border between Scotland and England, defined by the small river Sark, which flows into the nearby Solway Firth. It was historically the first village in Scotland, when following the old coaching route from London to Edinburgh. Gretna Green railway station serves both Gretna Green and Gretna.1:50,000 OS map 85 The Quintinshill rail disaster, the worst rail crash in British history, in which over 220 died, occurred near Gretna Green in 1915. Gretna Green sits alongside the main town of Gretna. Both are accessed from the A74(M) motorway. Gretna Green is most famous for weddings. The Clandestine Marriages Act 1753 prevented couples under the age of 21 marrying in England or Wales without their parents' consent. As it was still legal in Scotland to marry without such consent, couples began crossing the border into Scotland to marry. Marriage Gretna's "runaway ma ...

The Great Exhibition
The Great Exhibition of the Works of Industry of All Nations, also known as the Great Exhibition or the Crystal Palace Exhibition (in reference to the temporary structure in which it was held), was an international exhibition which took place in Hyde Park, London, from 1 May to 15 October, 1851. It was the first in a series of World's Fairs, exhibitions of culture and industry that became popular in the 19th century. The event was organised by Henry Cole and Prince Albert, husband of Victoria, Queen of the United Kingdom. Famous people of the time attended the Great Exhibition, including Charles Darwin, Karl Marx, Michael Faraday (who assisted with the planning and judging of exhibits), Samuel Colt, members of the Orléanist Royal Family and the writers Charlotte Brontë, Charles Dickens, Lewis Carroll, George Eliot, Alfred Tennyson and William Makepeace Thackeray. The opening music, under the superintendence of William Sterndale Bennett, was directed by Sir Georg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anvil
An anvil is a metalworking tool consisting of a large block of metal (usually forged or cast steel), with a flattened top surface, upon which another object is struck (or "worked"). Anvils are as massive as practical, because the higher their inertia, the more efficiently they cause the energy of striking tools to be transferred to the work piece. In most cases the anvil is used as a forging tool. Before the advent of modern welding technology, it was the primary tool of metal workers. The great majority of modern anvils are made of cast steel that has been heat treated by either flame or electric induction. Inexpensive anvils have been made of cast iron and low quality steel, but are considered unsuitable for serious use as they deform and lack rebound when struck. Structure The primary work surface of the anvil is known as the face. It is generally made of hardened steel and should be flat and smooth with rounded edges for most work. Any marks on the face w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterfowl
Anseriformes is an order of birds also known as waterfowl that comprises about 180 living species of birds in three families: Anhimidae (three species of screamers), Anseranatidae (the magpie goose), and Anatidae, the largest family, which includes over 170 species of waterfowl, among them the ducks, geese, and swans. Most modern species in the order are highly adapted for an aquatic existence at the water surface. With the exception of screamers, males have penises, a trait that has been lost in the Neoaves. Due to their aquatic nature, most species are web-footed. Evolution Anseriformes are one of only two types of modern bird to be confirmed present during the Mesozoic alongside the other dinosaurs, and in fact were among the very few birds to survive their extinction, along with their cousins the galliformes. These two groups only occupied two ecological niches during the Mesozoic, living in water and on the ground, while the toothed enantiornithes were the dominant b ...

Trip Hammer
A trip hammer, also known as a tilt hammer or helve hammer, is a massive powered hammer. Traditional uses of trip hammers include pounding, wikt:decorticate, decorticating and polishing of grain in agriculture. In mining, trip hammers were used for crushing metal ores into small pieces, although a stamp mill was more usual for this. In finery forges they were used for drawing out bloomery, blooms made from wrought iron into more workable Wrought iron, bar iron. They were also used for fabricating various articles of wrought iron, latten (an early form of brass), steel and other metals. One or more trip hammers were set up in a forge, also known variously as a hammer mill, hammer forge or hammer works. The hammers were usually raised by a cam and then released to fall under the force of Gravitation, gravity. Historically, trip hammers were often powered Hydropower, hydraulically by a water wheel. Trip hammers are known to have been used in Imperial China since the Western Han dyna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walkley Bank Tilt Marker
Walkley is a suburb of Sheffield, England, west of Burngreave, south of Hillsborough and north-east of Crookes. The area consists mainly of Victorian stone-fronted terraced housing and has a relatively high student population. It also has a number of independent shops and cafes. History The origin of the name Walkley comes from the Old English language with the original name being "Walcas Leah", meaning Walca's forest clearing.J. Edward Vickers, ''The Ancient Suburbs of Sheffield'', p.24 (1971) The early Anglo-Saxon village consisted of a few structures, mainly farm buildings and workmen's cottages. Most of the area was thick woodland with the few open quarters such as Crookesmoor and Bell Hagg Common being used for grazing cattle. Walkley was mentioned in several documents in the centuries after the Norman Conquest, in 1554 it was described as having several cottages and smallholdings worked by tenants of the Lord of the Manor of Sheffield. By this time the population of W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sheffield Outrages
The Sheffield Outrages were a series of explosions and murders by a small group of trade unionist militants carried out in Sheffield, England in the 1860s. Sheffield's early success in steel production had involved long working hours, in conditions which offered little or no safety protection. In '' The Condition of the Working Class in England in 1844'', Friedrich Engels quotes a local doctor, Dr. Knight, regarding the so-called "Grinder's Asthma" suffered by the Sheffield cutlery workers in the mid 19th century: The city became one of the main centres for trade union organisation and agitation in the United Kingdom. By the mid-late 1860s the majority of the objectives of the Chartist movement had been frustrated. These social and political reformers had not accomplished all they had hoped to, although they had succeeded in lobbying for the establishment of the first town council in 1843. (Eventually, the great majority of the items of their 'charter' did, in fact, become law). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trout
Trout are species of freshwater fish belonging to the genera '' Oncorhynchus'', '' Salmo'' and '' Salvelinus'', all of the subfamily Salmoninae of the family Salmonidae. The word ''trout'' is also used as part of the name of some non-salmonid fish such as ''Cynoscion nebulosus'', the spotted seatrout or speckled trout. Trout are closely related to salmon and char (or charr): species termed salmon and char occur in the same genera as do fish called trout (''Oncorhynchus'' – Pacific salmon and trout, ''Salmo'' – Atlantic salmon and various trout, ''Salvelinus'' – char and trout). Lake trout and most other trout live in freshwater lakes and rivers exclusively, while there are others, such as the steelhead, a form of the coastal rainbow trout, that can spend two or three years at sea before returning to fresh water to spawn (a habit more typical of salmon). Arctic char and brook trout are part of the char genus. Trout are an important food source for humans and wil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palmate Newt
The palmate newt (''Lissotriton helveticus'') is a species of newt found in Western Europe, from Great Britain to the northern Iberian peninsula. It is long and olive or brown with some dark spots. The underside is yellow to orange, and the throat, unlike in the similar smooth newt, always unspotted. A dark stripe runs along the head and through the eyes. Breeding males develop a distinct filament on the end of their tail, strongly webbed hind feet, and a low, smooth crest on their back. Habitats include forests, marshes, pastures or gardens. While on land, the newts are mainly nocturnal. After emerging from hibernation in spring, they move to stagnant, fish-free water bodies for breeding. After a courtship display, the male deposits a spermatophore that is picked up by the female. Larvae develop over after 1.5–3.5 months before metamorphosing into land-dwelling juveniles (efts). Sexual maturity is reached after two to three years, and the newts can reach a total age of up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Frog
The common frog or grass frog (''Rana temporaria''), also known as the European common frog, European common brown frog, European grass frog, European Holarctic true frog, European pond frog or European brown frog, is a semi-aquatic amphibian of the family Ranidae, found throughout much of Europe as far north as Scandinavia and as far east as the Urals, except for most of Iberia, Southern Italy, and the southern Balkans. The farthest west it can be found is Ireland. It is also found in Asia, and eastward to Japan. The nominative, and most common, subspecies ''Rana temporaria temporaria'' is a largely terrestrial frog native to Europe. It is distributed throughout northern Europe and can be found in Ireland, the Isle of Lewis and as far east as Japan. Common frogs metamorphose through three distinct developmental life stages — aquatic larva, terrestrial juvenile, and adult. They have corpulent bodies with a rounded snout, webbed feet and long hind legs adapted for swim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
