One of many similar balloons used to direct the fire of artillery and observe the movements of the enemy, a service of considerable danger as the baloonists are constantly exposed to airplane attack. Each observer is harnessed to a parachute and jumps when the balloon is attacked and in danger of destruction. (Copyright by C. P. I., from W. N.
