The dialects in these parts reflect the farming practices that were at the heart of rural life for centuries. South-eastern dialects have incorporated many words relating to traditional methods of harvesting, haymaking and thatching. These are all well-documented in the Survey of English Dialects recordings. Raffling refers to a shock (group) of 10 sheaves of wheat, for example, and yielding is a word for a bundle of straw used to make thatched rooves like this one in Oakley, Hampshire:

For example, in 1959, Harry Prior from East Harting in Sussex describes making thatched rooves with spars and courses. He also talks about harvesting corn with a rake. Other informants explained the different implements used for mowing and cutting crops, including fag hooks (sickles) and leas (scythes).
