Carrington Moss of years this raises the level of peat and forms a gently sloping dome (hence, raised). Such areas support a wide range of flora and fauna; "Sphagnum balticum", a medium-sized bog moss, was recorded on Carrington Moss in the 1880s, although locally it is now presumed to be extinct. Lancashire- or bog asphodel ("Narthecium ossifragum"), white beak-sedge ("Rhynchospora alba"), cranberries, bog-rosemary ("Andromeda polifolia"), and the cotton sedge have also been recorded. In 1923 species of trees recorded by E. Price Evans for the "Journal of Ecology" included English oak ("Quercus robur"), and common ash ("Fraxinus excelsior"). Undergrowth included common hazel
Oxy-fuel welding and cutting is what chemically combines with the fuel to produce the heat for welding. This is called 'oxidation', but the more specific and more commonly used term in this context is 'combustion'. In the case of hydrogen, the product of combustion is simply water. For the other hydrocarbon fuels, water and carbon dioxide are produced. The heat is released because the molecules of the products of combustion have a lower energy state than the molecules of the fuel and oxygen. In oxy-fuel cutting, oxidation of the metal being cut (typically iron) produces nearly all of the heat required to "burn" through
