Rundale
The rundale system (apparently from the Irish Gaelic words "Roinn" which refers to the division of something and "Dáil", usually meaning meeting or assembly) was a form of occupation of land in Ireland, somewhat resembling the English common field system. The land is divided into discontinuous plots, and cultivated and occupied by a number of tenants to whom it is leased jointly. The system was common in Ireland, especially in the western counties. In Scotland, where the system also existed, it was termed "run rig" (from "run", and "rig" or ridge). History. Rundale farming systems in Ireland existed from  the Early Medieval Period right up until the time of the First World War. The rundale system of agriculture consisted of nucleated villages known as "clachans". Usually the land was of poor quality and the population of people trying to make a living was intensive. The main "clachan" area where the small thatched cottages were concentrated, was situated in a cluster on the best land (the infields) which was surrounded by mountain or grazing land of inferior quality (the outfields) where the livestock was grazed during summer or dry periods, a practice known as transhumance or as "booleying". All the  sheep or cattle of the village were grazed together to alleviate pressure on growing crops and also provided fresh pasture for livestock. In the remote western areas of Ireland where the rundale system was most commonly seen, the land was a complex mixture of arable, rough and bogland. It was a difficult task to ensure that each tenant had an equal share of good and poor land. Rundale clachans and their transhumance pastures, also known as Booley, Boley, Bouley, Bualie and Boola can still be seen in the parish of Kilcommon in Erris, County Mayo, in many townlands such as  Gortmelia, Inver and Glengad where clusters of cottages can be seen on the hillsides with land in narrow strips running down to the sea. These names survive in place names such as Buaile h'Anraoi in Kilcommon where the landscape still shows very clearly the layout of the Rundale system. The practise of booleying provided a safety valve in that it allowed maximisation of available human resources. Seasonal migration to Scotland and England superseded this ancient system and went hand-in-hand with more permanent emigration to the United States. Booleying alleviated pressure on the growing crops and provided fresh pasture  for livestock while the migratory worker to the potato fields of Ayrshire or the Lothians earned sufficient income to allow him and his family to live at home for most of the year. The average holding on the small farms of County Mayo was only five acres, insufficient to maintain a family for more than part of the year. Booleying is mentioned in the Brehon Laws. John O'Donovan of the Ordnance Survey (1838) noted that the people owned houses in two townlands, one of which was a booley. ""It is a great habit among the people of the island to  have two townlands and houses built on each where they remove occasionally with their cattle. The townlands are held under one lease and one of these farms is called a Bouley." " The demise of booleying in Ireland came about in the 19th century when incoming landlords began to impound livestock which trespassed on their property. Retrieval fines were prohibitive and there was a consequent reduction in the number of cattle kept.
