PLATE XVII.
THE PASSCHENDAELE RIDGE.
A photograph taken in the north of the Salient with the long low line of the Passchendaele Ridge in the distance. It gives some idea of the way in which the whole land surface is covered with weeds and shell-pits.
PLATE XVIII.
A "PILLBOX."
The wreck of one of the German Pillboxes, of very heavily reinforced concrete, such as were brought into use with some flourish of trumpets in July, 1917, but very successfully countered by General Plumer's methods later on.
