Just where the opposing lines reach the top of the Ridge they both bend from their main north and south direction towards the southeast, and continue in that course for several miles. At the point or salient of the bending, in the old enemy position, there is a crater of a mine which the English sprang in the early morning of the 1st of July. This is the crater of the mine of Beaumont Hamel. Until recently it was supposed to be the biggest crater ever blown by one explosion. It is not the deepest: one or two others near La Boisselle are deeper, but none on the Somme field comes near it in bigness and squalor. It is like the crater of a volcano, vast, ragged, and irregular, about one hundred and fifty yards long, one hundred yards across, and twenty-five yards deep. It is crusted and scabbed with yellowish tetter, like sulphur or the rancid fat on meat. The inside has rather the look of meat, for it is reddish and all streaked and scabbed with this pox and with discoloured chalk. A lot of it trickles and oozes like sores discharging pus, and this liquid gathers in holes near the bottom, and is greenish and foul and has the look of dead eyes staring upwards. [Illustration: An Artillery Team taking the Bank] All that can be seen of it from the English line is a disarrangement of the enemy wire and parapet. It is a hole in the ground which cannot be seen except from quite close at hand. At first sight, on looking into it, it is difficult to believe that it was the work of man; it looks so like nature in her evil mood. It is hard to imagine that only three years ago that hill was cornfield, and the site of the chasm grew bread. After that happy time, the enemy bent his line there and made the salient a stronghold, and dug deep shelters for his men in the walls of his trenches; the marks of the dugouts are still plain in the sides of the pit. Then, on the 1st of July, when the explosion was to be a signal for the attack, and our men waited in the trenches for the spring, the belly of the chalk was heaved, and chalk, clay, dugouts, gear, and enemy, went up in a dome of blackness full of pieces, and spread aloft like a toadstool, and floated, and fell down.
