he first successful photograph was taken in November,
1914, of the village of Neuve Chapelle. The photographic section then
consisted of two officers and three men, with two cameras and a
portable box of chemicals. At the present day it contains 250 officers
and 3,000 men--with a large training school; and its prints have been
issued by the million.

Meanwhile the development of our aircraft fire had driven the aerial
photographer from a height of 3,000 feet up to a height of 22,000,
where, but for invention, he might have perished with cold, or found
it impossible to breathe. But intelligence pursued him, providing him
with oxygen and with electric heating apparatus in the upper air. And
when, on the other hand, he or his comrade swooped down to within a
few hundred feet of the earth, in order to co-operate in attack with
infantry or Tanks, again intelligence came into play, inventing a
special armoured machine for the protection of the new tactics.

The growth of "wireless," as a means of air-communication, is another
astounding chapter in this incredible story. Only _one_ of the
machines which left with the original Expeditionary Force was fitted
with "wireless" apparatus, and it was not used till the first Battle
of the Aisne, when co-operation with the artillery first began. There
are now 520 officers in the "wireless" branch and 6,200 other ranks;
while there are 80 "wireless" stations in France alone and several
hundred battery stations. "Wireless" telephony, too, has been made
practical since 1917; and over a range of some 75 miles has been of
deadly use to the artillery, especially at night, when the watcher in
the skies becomes aware of lighted aerodromes, or railway stations,
behind the enemy lines.

"Many wonders there be, but none more wonderful than man," said
Sophocles, in the fifth century before Christ, and he gives the
catalogue of man's discoveries, as the reflective Greek saw it, at
that moment of the world's history. Man, "master of cunning," had made
for himself ships, ploughs, and houses, had tamed the horse and the
bull; had learned how to snare wild creatures for food, had developed
speech, intelligence, civilisation. Marvels indeed! But had it ever
occurred to such a Greek to ponder the general stimulus given to human
faculty by war? Probably, for the wise Greek had thought of most
things, and some reader of these pages who knows his rich literature
better than I do, will very likely remembe
