©Committee on Public Information STUDYING THE ANATOMY OF A MACHINE-GUN These husky lads are preparing for the day when they will become America's golden eagles of the air. From their vantage point inthe air they will watch every movement of the enemy. The far-flung battle line will stretch beneath them, with men appearing as ants, serried rows of trenches as mud-cracks on the face of the ground, and the dazzling flashes of big guns but as thefeeble coruscations of afirefly on adistant hill. The earth will appear to them as but a map in slight relief, the green betokening the grass field, the yellow the ripening grain, the dark patches the woods, the mirror-like gleam a river or a lake, and the white ribbons the macadam road. Andthe two streaks of thin brightness are the traffic polished surfaces of the rails of a railway to the front, stretching across the picture as though ruledbysome mighty pen.
