Ray, who made a tour along the eastern coast in that year, says, " We observed little or no fallow ground in Scotland; some ley ground we saw, which they manured with sea wreck.
The ground has to be thoroughly cleared of stones, manured and trenched, and the corms are planted in ridges.
Upon the London Clay the land is generally heavy and stiff, but very fruitful when properly manured and cultivated.
Maize or Indian corn was cultivated on patches of ground where, as in the Hindu jam, the trees and bushes were burnt and the seed planted in the soil manured by the ashes.
The ground should be kept free of weeds by frequent hoeing and, if not subject to periodical alluvial floods, manured yearly.
