The right-hand portion of this manuscript features several annotated red crosses. These represent observation and trigonometrical stations from which angular measurements were been taken. To the far left, red-ink lines describe the Monmouth River, highlighting it as the boundary separating Herefordshire and Monmothshire. The borders of the published sheet can be seen in pencil.
