North Forty Foot Bank

The North Forty Foot Bank is a settlement which runs about 6 miles along the North Forty Foot Drain, about five to nine miles north-west of Boston Lincolnshire, England. It begins just south of the parish of Chapel Hill and runs along the drain to Toft Tunnel, just north of Hubberts Bridge. Despite its length, it only consists of the area on the north side of the drain, which was built in 1720 by Earl Fitzwilliam.
The North Forty Foot Bank forms the boundary between Harts Grounds and Pelhams Lands.

A row of 29 brick and slate cottages were built between the North Forty Foot Bank and the hamlet of Brothertoft by Major John Cartwright to accommodate the workers of his red brick woad mill in the late 18th century. This place was then called Isatica, which is Latin for "woad". After Cartwright left Brothertoft for London, the hamlet of Isatica fell into ruin and disappeared.
