southward passage, and after Carrdyke Farm, there is another scheduled section. It passes to the east of Martin and the western end of Timberland Delph, before following a large S-shaped course to the east of Timberland. Immediately afterwards there are two more scheduled sections, one to the north of Fen Road, Timberland and the second to the south. The dyke passes to the east of Walcott and along the northern and eastern edge of Billinghay, where it joins Billinghay Skirth, which drains into the River Witham. The continuation of Billinghay Skirth to the south-west uses the course of Car Dyke, and when it turns to the west near North Kyme, Car Dyke continues southwards, running along the western edge of North Kyme to reach the River Slea at Ferry Bridge. The River Slea makes a right-angled turn at the junction, and then turns to the east again, with Car Dyke continuing southwards, and now part of Midfodder Dike. Its course has then been reused by Hodge Dyke, which again makes a right-angled turn at the junction, until it crosses Heckington Eau, which becomes Head Dike as it continues eastwards. Continuing to the south, it reaches Littleworth Drove, where a house has been built over the remains. It passes under the A17 road, and then Carterplot Road runs parallel to it. It is crossed by the East Midlands Railway line from to , Little Hale Drove, where there is another Car Dyke farm, Helperingham Eau, North Drove and the Sleaford to railway line. At the railway crossing, it turns to the west and then the south west, where there is another scheduled section. It runs to the east of Swaton, with Cardyke Farm to its east, and continues past Horbling and Billingborough until it is crossed by Billingborough Lode, which drains into the South Forty-Foot Drain. There is a large moated site by the junction. Near Pointon, it is crossed by Fen Road, Pointon Lode and Millthorpe Drove, while near Dunsby there is another Car Dyke Farm. Soon its course is joined by Rippingale Running Dike, and between Haconby and Morton there is another Cardyke Farm, before the Car Dyke passes through a small village called Dyke, where there is another scheduled section. At Bourne the dyke makes right-angled turns to the east and then the south, to join Bourne Eau, which continues westwards to the centre of the town, where
