At one time the area just behind Vimy Ridge was plentifully sprinkled
with enemy shells which had failed to explode. As these were considered
a great source of danger they were indicated by "danger boards" nailed
to pointed stakes driven into the ground.
On one occasion, seeing a man engaged in so marking the resting-place
of a "dud"--he was a cheerful Cockney, who whistled as he went about
his job--I was much amused (though somewhat scared) to see him stop at
a nearby shell, select a "danger board," pick up the shell, and proceed
to use it as a hammer to drive the stake into the ground!--_H. S. A.
