a certain action. When he wrote
his account of it, it was submitted to the general who was his
friend; and the general carelessly passed one little statement which
no Chief of Intelligence of any army would ever have passed and
probably no correspondent of experience would have had the temerity
to submit to the censor unless he wanted to be responsible for the
death of men who were his hosts and his friends. For the writer
stated that he saw the battle from this tower.

Now the London papers reach Holland at four o'clock in the afternoon
where they are seized promptly by the tentacles of the German
Intelligence Service, which did not need to undertake any "picture
puzzle work" on this occasion. It was plain as day that this tower
must be used as an artillery observation post by the enemy. From
there he could see the fall of shells from his batteries and know
whether they were "on" or not. Out of the blue sky the next morning,
came a German artillery concentration which brought the tower down
like a house of cards, and many British soldiers billeted in the
neighborhood were killed or wounded.

In order to deepen the shroud of mystery over his side which baffles
the enemy, many military men would undoubtedly make the press merely
the herald of official bulletins. The British Admiralty carried out
this system to the letter, as a navy may better than an army, in the
resistance of the German submarine campaign. Thus the "Untersee-boots"
came out from Kiel or Zeebrugge and disappeared in the mists of the
North Sea with no message of how they had been destroyed when they
never returned.

The Intelligence Service in common with army transport and the
sanitary service and every other expert branch has for its object
the conserving of the lives of your own soldiers and the taking of
those of the enemy, best expressed by an infantry attack on the
enemy's trenches, whether to gain a few hundred yards or a belt of
eight to ten miles as in the case of the French attack in Champagne
in September, 1915, and the German attack on Verdun in February,
1916. The first step is the concentration of batteries for
artillery preparation. Gradually, these guns all try out their range
with the aeroplanes spotting the fall of their shells. Then, at the
scheduled minute they loose their blasts upon the front line
trenches which are to be taken. In front of the trenches, of course,
are the elaborate barbed-wire entanglements. These are often twen
