See also:HAZEL (0. Eng. hresell; cf. Ger. Hasel, Swed. and See also:Dan. Kassel, &c.,; Fr. noiselier, coudrier)
, botanically corylus, a genus of shrubs or See also:low trees of the natural See also:order Corylaceae
.
The See also:common See also:hazel, Corylus Avellana (fig
.
I), occurs throughout See also:Europe, in See also:North See also:Africa and in
central and See also:Russian See also:Asia, except the northernmost parts
.
It is commonly found in hedges and coppices, and as an undergrowth in See also:woods, and reaches a height of some 12 ft.; occasionally, as at Eastwell See also:Park, See also:Kent, it may attain to 30 ft
.
According to See also:Evelyn (Sylva, p
.
35, 1664),
hazels " above all affect See also:cold, barren, dry, and sandy soils; also mountains, and even rockie ground produce them; but more plentifully if somewhat moist, dankish, and mossie.'' In Kent they flourish best in a calcareous See also:soil
.
The bark of the older stems is of a See also:bright See also: 2) are I to 21 in. See also:long, and occur 2 to 4 in a raceme; when in unusual See also:numbers they may be terminal in position . The See also:female flowers are small, sub-globose and sessile, 1 It has been supposed that the origin is to be found in O . Eng. has, a behest, connected with hatan = Ger. heissen, to give orders : the hazel-wand was .the See also:sceptre of authority of the shepherd chieftain (Irocµ,}v aawv) of olden times, see See also:Grimm, Gesch. d. See also:deutsch . Sprache, p. roi6, 1848 . The See also:root is kas-, cf . See also:Lat. corulas, corylus; and the See also:original meaning is unknown . resembling See also:leaf-buds, and have protruding See also:crimson stigmas; the See also:minute inner bracts, by their enlargement, See also:form the palmately lobed and cut involucre or husk of the nut . The ovary is not visible till nearly midsummer, and is not fully See also:developed before autumn . The nuts have a length of from i to f in., and grow in clusters . See also:Double nuts are the result of the equal development of the two carpels of the original See also:flower, of which ordinarily one becomes abortive; See also:fusion of two or more nuts is not uncommon . From the See also:light-brown or brown See also:colour of the nuts the terms hazel and hazelly, i.e . " in See also:hue as hazel nuts " (See also:Shakespeare, Taming of the See also:Shrew, ii . 1), derive their significance.' The See also:wood of the hazel is whitish-red, See also:close in texture and pliant, and has when dry a See also:weight of 49 lb per cub. ft.; it has been used in See also:cabinet-making, and for toys and turned articles . Curiously veined veneers are obtained from the roots; and the root-shoots are largely employed in the making of See also:crates, coalcorves or baskets, hurdles, withs and bands, See also:whip-handles and other See also:objects . The rods are reputed to be most durable when from the driest ground, and to be especially See also:good where the bottom is chalky . The light See also:charcoal afforded by the hazel serves well for crayons, and is valued by See also:gunpowder manufacturers . An objection to the construction of hedges of hazel is the injury not in-frequently done to them by the nut-gatherer, who " with active vigour crushes down the See also:tree " (See also:Thomson's Seasons, " Autumn "), and otherwise See also:damages it . The filbert,2 among the numerous varieties of Corylus Avellana, is extensively cultivated, especially in Kent, for the See also:sake of its nuts, which are readily distinguished from See also:cob-nuts by their ample involucre and greater length . It may be propagated by suckers and layers, by grafting and by See also:sowing . Suckers afford the strongest and earliest-bearing See also:plants . Grafted filberts are less liable than others to be encumbered by suckers at the root . By the See also:Maidstone growers the best plants are considered to be obtained from layers . These become well rooted in about a twelvemonth, and then, after pruning, are bedded out in the nursery for two or three years . The filbert is economically grown on the See also:borders of plantations or orchards, or in open spots in woods .
It thrives most in a light See also:loam with a dry subsoil; rich and; in particular, wet soils are unsuitable, conducing to the formation of too much wood
.
Plantations of filberts are made in autumn, in well-drained ground, and a space of about to ft. by 8 has to be allowed for each tree
.
In the third See also:year after planting the trees may require root-pruning; in the fifth or See also:sixth they should See also:bear well
.
The nuts grow in greatest abundance on the extremities of second year's branches, where light and See also:air have ready See also:access
.
To obtain a good tree, the practice in Kent is to select a stout upright shoot 3 ft. in length; this is cut down to about 18 in. of which the See also:lower 12 are kept See also:free from out-growth
.
The See also:head is pruned to form six or eight strong offsets; and by judicious use of the See also:knife, and by training, preferably on a hoop placed within them, these are caused to grow outwards and upwards to a height of about 6 ft. so as to form a bowl-like shape
.
Excessive luxuriance of the laterals may be combated by root-pruning, or by checking them See also:early in the See also:season, and again later, and by cutting back to a female blossom bud, or else spurring nearly down to the See also:main See also:branch in the following See also:spring
.
Filbert nuts required for keeping must be gathered only when quite ripe; they may then he preserved in dry See also:sand, or, after drying, by packing with a•sprinkling of See also:salt in See also:sound casks or newflower-pots
.
Their different forms include the Cosford, which are thin-shelled and oblong; the Downton, or large square nut, having a lancinated husk; the See also:

See also: The leaves of the hazel are frequently found See also:mined on the upper and under See also:side respectively by the larvae of the ,moths Lithocolletis coryli and L . Nicelii . Squirrels and dormice are very destructive to the nut See also:crop, as they not only take for See also:present See also:consumption but for a See also:store for future See also:supply . Parasitic on the roots of the hazel is found the curious leafless Lathraea Squamaria or See also:toothwort . The See also:Hebrew word luz, translated " hazel " in the authorized version of the See also:English See also:Bible (Gen. See also:xxx . 37), is believed to signify " See also:almond " (see See also:Kitto, Cycl. of Bibl . Lit. ii . 869, and iii . 811, 1864) . A belief in the efficacy of See also:divining-rods of hazel for the See also:discovery of concealed objects is probably of remote origin (cf . See also:Hosea iv . 12) .
