Fig. 3. A corner of the excavation trench at Sumburgh, showing ard marks in relation to earlier
structures. 1 = stones laid flat; 2 = slabs on edge. Stippling represents dark ploughsoil, unstippled part
is white sand. These ard marks are those of the second period, when they were formed on the surface of
a drift of sand blown by a SE gale against the side of the house. Above the sand-drift a new ploughsoil
subsequently developed. The stippled area at the top of the plan is the earthen wall of the house, which
is sloping down and dipping under the sand-drift. Ploughing of the soil which then formed on the
sand-drift produced brown earth ard marks in the sand surface, and two of these marks are seen to
continue into the wall-material of the house, where they appear as streaks of white sand which the ard
has dragged into the wall-fill. The three erect slabs in the NE corner are the projecting tops of the sides
of a slab-formed box which had been built on the sloping wall of the house and which was buried under
the sand-drift. The ard marks are seen to continue into the area of the box, demonstrating the
manoeuvrability of the ard which must have been lifted sharply to clear the projecting slabs.
