Imagine burrowing all that way down in the belly of the earth, with Hell going on overhead, burrowing and listening till they got right under the German trenches--hundreds and hundreds of yards of burrowing.

And here remained the result of their work, on the earth at least, if not on humanity.

The latter had disappeared; but the great chasm, with one mound in the centre at the bottom, and one skull placed on top of it, remained.

They had cut little steps down one of its sides, and had cleared up all the human remains and buried them in this mound.

That one mound, with the little skull on the top, at the bottom of this enormous chasm, was the greatest monument I have ever seen to the handiwork of man.
There was another fairly large mine here, just by the Bapaume Road, and there was a large mine at Beaumont-Hamel, and also the "Cough-drop" at High Wood.
