VII. Whether preparations are being made for an attack (discoverable by ear as well as eye), or bombardment, etc. (from examination of shell dumps, etc.).
VIII. Position of machine guns (Pill-boxes or other), mortars, etc.
IX. Condition of intervening ground and of the wire entanglements.
X. Effects of recent bombardments.
