north-west corner of the exclave north of Biggin Wood. Oddly, the parish church of Everton, Bedfordshire was in this enclave (with half the village) and not in its civil parish. This was because Everton and Tetworth had always remained a single ecclesiastical parish. Kent The county had two riparian semi-exclaves after 1844: North Woolwich. The town and parish of Woolwich had two parcels of territory on the north bank of the Thames Estuary, surrounded by Essex. Before the 19th century these were just marshland, but in 1847 North Woolwich railway station was opened in the western, smaller one to give the town a railway route to London via a ferry. This created the settlement of North Woolwich. The two riparian semi-exclaves were transferred to the County of London with the town in 1889. Previously, the boundary between Kent and Essex ran along the middle of the estuary here. Lancashire The historic county of Lancashire had no true exclaves, although a large part of it was separated from the rest at high tide and counted as a semi-exclave (total 1): Furness (1). The North Lonsdale area of Lancashire, or "Lancashire North of the Sands", was cut off from the main body of Lancashire by Westmorland and Morecambe Bay, and so was regarded as a semi-enclave. However, Morecambe Bay dries out at low tide and an ancient right of way for wheeled traffic runs across it (presently in charge of the King's Guide to the Sands). The area was transferred to Cumbria by the Local Government Act 1972. Administrative exclave: Lees Urban District was from 1889 an exclave of the administrative county of Lancashire, separated from the rest of the county by the County Borough of Oldham (shown within the Salford Hundred in the map to the right), and enclosed on the other side by Saddleworth Urban District in the West Riding of Yorkshire. The urban district was abolished by the Local Government Act 1972, taking effect on 1 April 1974, with its former area transferred to the newly created metropolitan county of Greater Manchester, along with much of Salford Hundred, to form part of the new Metropolitan Borough of Oldham, where it was also joined by Saddleworth. Riparian semi-exclaves: River Mersey. The border with Cheshire ran along the River Mersey, but the river had many meanders and was liable to change its course. This left many portions of both counties on
