47. _HARD FESCUE GRASS_ (_Festuca duruscula_, Fig. 30) is common in pastures, meadows, and waste grounds. It springs early, affords excellent food for all kinds of cattle; and, in good ground, yields a plentiful crop. 48. _FLOTE FESCUE GRASS_ (_Festuca fluitans_, Fig. 31).--This plant, which grows almost exclusively in wet ditches, and in ponds, is so favourite a food of horses and swine, that they will sometimes even endanger their lives to obtain it. A farmer, who resided some years ago at Ruscomb, in Berkshire, assured Mr. Stillingfleet that he had known a field of four acres (which was nearly always covered with water) afford sufficient nutriment to maintain five farm horses, in good condition, from April to the end of harvest, without any other food; and that it yielded even more than they could eat. The Cottenham and Chedder cheeses are said, in a great measure, to derive their celebrity from the cows feeding on this grass. Its seeds are small, and are remarkable for their sweet flavour and nutritious qualities. They are annually collected in Poland, and are exported thence, into Germany, and other parts of the continent, under the name of _manna seeds_. These are used in soups, gruel, and puddings, even by persons of the first rank and consequence. When ground into flour, they are convertible into bread, which is little inferior to that made of wheat. The bran of these seeds is stated by Linnæus to be useful as a medicine for horses that are troubled with worms. Geese are fond of the seeds, and well know where to find them. It is remarkable that these seeds have hitherto been entirely neglected in England; though without difficulty they might be obtained in sufficient quantity to prove beneficial. 49. _The COMMON REED_ (_Arundo phragmites_, Fig. 33) grows in ditches, ponds, and by the sides of rivers, attaining the height of six or seven feet, and flowering about the month of July. Reeds are frequently made into screens or fences for gardens, and they are considered particularly eligible for sheltering tender plants from injury by cold, or blighting winds. They likewise make excellent _weavers' combs_; and, when nailed across a frame of wood-work, are frequently employed as a foundation for plaster floors. They are sometimes made into chair bottoms; and into thatch for cottages and out-buildings. From the flowers of the reed the country people of Sweden extract a green dye, which they occasionally use for woollen cloth; and we are informed that, from the dried roots, a flour may be made, which is capable of being converted into a wholesome and nutritive bread.
