Title: A pocket periscope
Caption: Small pocket periscope. The soldier, concealed behind an intrenchment, can quickly attach this tiny instrument to the barrel of his rifle, to a pole, or to a trench digging tool, and can readily observe, by means of the two circular mirrors, the movements of his antagonists in the distance without exposing himself to any tance without exposing himself.
