This drawing covers the course of the River Crouch. Field boundaries on the marshlands of New England Island and Potten Island are drawn with a waved line to distinguish them from those on dry land. The marshes were used for arable farming, especially wheat. On the right-hand side of the plan is the mouth of the Whittaker Channel. Signal houses are noted on either side, and the salt marshes are indicated by irregular lines.
