Given the following context:  Stretford was part of the ancient parish of Manchester, within the historic county boundaries of Lancashire. Following the Poor Law Amendment Act of 1834, a national scheme for dealing with the relief of the poor, Stretford joined the Chorlton Poor Law Union in 1837, one of three such unions in Manchester, before transferring to the Barton-upon-Irwell Poor Law Union in 1849. In 1867, Stretford Local Board of Health was established, assuming responsibility for the local government of the area in 1868. The board's responsibilities included sanitation and the maintenance of the highways, and it had the authority to levy rates to pay for those services. The local board continued in that role until it was superseded by the creation of Stretford Urban District Council in 1894, as a result of the Local Government Act 1894. Stretford Urban District became the Municipal Borough of Stretford in 1933, giving it borough status in the United Kingdom. Stretford Borough Council was granted its arms on 20 February 1933. The roses are the red roses of Lancashire, and the lion in the centre represents John of Gaunt, 1st Duke of Lancaster. Above the lion are a crossed flail and scythe; the flail comes from the arms of the de Trafford family; the scythe is a reminder of the agricultural history of the area; the thunderbolts above represent the importance of electricity in Stretford's industrial development. The boat at the bottom represents Stretford's links to the sea via the Manchester Ship Canal.In 1974, as a result of the Local Government Act 1972, the Municipal Borough of Stretford was abolished and Stretford has, since 1 April 1974, formed part of the Metropolitan Borough of Trafford, in Greater Manchester. Trafford Town Hall – previously Stretford Town Hall – is the administrative centre of Trafford.  answer the following question:  The scythe is a reminder of the agricultural history of what area?
Answer:
Stretford Borough
