About a mile from Castlesteads, descending by a rocky ravine in an easterly direction, is a remarkable hollow called Sale Bottom, where are the remains of mounds and earthworks, to all appearance of a strategic character--perchance the battlefield on which the owners of the fold on Castlesteads have struggled to defend themselves and their property. It is a narrow area of level land, bounded on the north side by an escarpment of limestone more or less bold; on the opposite side is a more regular slope, while the ends are gorges more or less rocky. Across the level area of this bottom have been formed five or six embankments of earth and stones running from the rocks on one side and on the other ending in counter entrenchments, two of which, at about twenty-five yards apart, run parallel along the slope of the hill, and so defending the most approachable side. The entrenchment at the upper end has also a ditch on the outside and runs between the cliff in one ravine over a hill to another ravine. Scattered over this area are also seven or eight mounds, which lead us to suppose that after the action was over the dead were buried on the field. The principal mound is circular, nine yards in diameter; near it is another, forty yards long and about five broad. These are of earth and stones, and have been made of the materials forming one of the breastworks, parts of which are still left at each end; besides these, further up, are three irregular shaped ones, about ten yards long each by five; there are also three other smaller ones in different places, all within the area of the entrenchments. These mounds have never been opened, so that no idea can be formed of the people by whom they were formed. The word Sale is by some supposed to mean strife or battle, and possibly the various forms of Sel and Sill may be of similar derivation, for example, Sill How, near Odindale. On the eastern slope of Sill How are the remains of raised banks of earth and stones running in different directions, apparently for a similar purpose to those in Sale Bottom--defence against the attacks of horsemen or chariots. Crowning the hill, not far from the stone circles is a mound which, on being opened, was found to contain in the centre a small chamber formed by four flat stones set edgewise, making a cavity about eighteen inches by ten and six deep; this contained a quantity of ashes and charred bones; over it was laid a rude limestone slab about three feet long by two. Upon this was loose earth and then another much larger stone. Outside in the body of the mound were also found quantities of human bones and teeth and also the teeth of horses. Amongst the earthworks are one or two mounds, one of which contained human bones, miscellaneously thrown in at a slight depth. The south-west slope of the hill is called "Outliers Brow," on which, on making a road, a bronze spear-head was found.
