Enclosures with hedges in England

691. The oldest enclosures in England are in Kent and Essex, and seem to have been formed of hawthorn, sloe, crab, hazel, dogwood, &c. taken from the copses, and planted promiscuously; but now almost all field or fence hedges are formed of single or double rows of hawthorn, with or without trees planted at regular distances to shoot up for timber.
