"At last the trench zone has been crossed; the country in back of it appears to be strewn with pits and funnels caused by the explosion of big caliber shells. Here and there destroyed villages are to be seen from which dark pillars of smoke arise. Then the first roadway about which information is to be gathered appears. Peacefully it lies in the sunlight. Farther toward the west, however, the street becomes more lively; but the black specks which move down there are only a few automobiles which most likely carry some members of the general staff of the enemy and offer nothing worth while observing. But a little farther back a dark line and many small specks appear--detachments on the march. The observer leans over his map, compares, looks down once more, then marks the observation on his map and the time at which it was made, and on goes the journey. In the streets of a larger place, which is reached soon afterward, a crowd of people are observed; in front of a church are standing at regular distances a number of wagons, a short wagon in front and back of it shapes that look like a frame--cannon. The observer continues to make marks on his map and at the same time a sharp sound is heard at his side and in the upper plane a slash appears. He waves his hand and the pilot sharply turns to the left. The observer reaches for a bomb and holds it over the edge of the aeroplane, drops it, and immediately afterward a flash appears among the cannon and the crowd on the market place disperses in wild flight. Another wave of the hand, another turn to the left, another bomb. The result is satisfactory; at least one cannon has been destroyed. But now it begins to become unpleasant; to the right and to the left, in front and in back, small white clouds arise; down there the bombardment has begun and it must make quite a loud noise which, however, is drowned in the noise of the motor. The pilot stops the motor and silently and gently the aeroplane descends into less dangerous heights; then the motor again begins to work and the aeroplane quickly turns its course toward the southwest following the white band of the country road.
