ction had completed breakfast.
The methodical regularity of hours kept by the German pilots added
considerably to the comfort and convenience of the section by allowing
them to time their hours of sleep, their meals, or an afternoon run by
the O.C. on the motor into the near-by town, so as to fit in nicely
with the duty of anti-aircraft guns.

On this morning at the usual hour the aeroplane appeared, and the
gunners, who were waiting in handy proximity to the cars, jumped to
their stations. The muzzles of the two-pounder pom-poms moved slowly
after their target, and when the range-indicator told that it was
within reach of their shells the first gun opened with a trial beltful.
"Bang--bang--bang--bang!" it shouted, a string of shells singing
and sighing on their way into silence. In a few seconds,
"Puff--puff--puff--puff!" four pretty little white balls broke out and
floated solid against the sky. They appeared well below their target,
and both the muzzles tilted a little and barked off another flight of
shells. This time they appeared to burst in beautiful proximity to the
racing aeroplane, and immediately the two-pounders opened a steady and
accurate bombardment. The shells were evidently dangerously close to
the 'plane, for it tilted sharply and commenced to climb steadily; but
it still held on its way over the British lines, and the course it was
taking it was evident would bring it almost directly over the Blue
Marines and their guns. The pom-poms continued their steady yap-yap,
jerking and springing between each, round, like eager terriers jumping
the length of their chain, recoiling and jumping, and yelping at every
jump. But although the shells were dead in line the range was too
great, and the guns slowed down their rate of fire, merely rapping off
an occasional few rounds to keep the observer at a respectful distance,
without an unnecessary waste of ammunition.

Arrived above them, the aeroplane banked steeply and swung round in a
complete circle.

"Dash his impudence," growled the captain. "Slap at him again, just for
luck." The only effect the resulting slap at him had, however, was to
show the 'plane pilot that he was well out of range and to bring him
spiraling steeply down a good thousand feet. This brought him within
reach of the shells again, and both guns opened rapidly, dotting the
sky thickly with beautiful white puffs of smoke, through which the
enemy sailed swiftly. Then suddenly another shape a
