disappeared into long subterranean passages and emerged among
a lot of soldiers gaily eating as they stood. Close by were a group of
men practising with hand-grenades made harmless for the
occasion. I followed the Commandant round a corner, and we
gazed at I forget what. "Don't stay here," said the Commandant. I
moved away. A second after I had moved a bullet struck the wall
where I had been standing. The entire atmosphere of the place, with
its imminent sense of danger from an invisible enemy and fierce

grand essential truth of the front, namely, that the antagonists are

adjective to apply to those activities.

Once, after a roundabout tour on foot, one of the Staff Captains
ordered an automobile to meet us at the end of a certain road. Part
of this road was exposed to German artillery four or five miles off.
No sooner had the car come down the road than we heard the
fearsome sizzling of an approaching shell. We saw the shell burst
before the sound of the sizzling had ceased. Then came the roar of
the explosion. The shell was a 77-mm. high-explosive. It fell out of

was an exact and a rather terrifying operation. It showed that the
invisible Germans were letting nothing whatever go by; but it did
seem to me to be a fine waste of ammunition, and a very stupid
application of a scientific ideal; for while shelling it the Germans
