Seen from afar, as I knew of old, that was exactly what the trenches looked like; but from the inside they appeared more solid and rather deeper than any grave dug for the dead. The whole thing put me more in mind of primitive ship-building--the great ribs leaning outwards--flat timbers in between--and over all sand-bags and sometimes wire-work with the precise effect of bulwarks and hammock-netting. Even the mouths of dug-outs were not unlike port-holes flush with the deck; and many a piquant glimpse we caught in passing, bits of faces lit by cigarette-ends and half-sentences or snatches of sardonic song; then the trench would twist round a corner into solitude, as a country road shakes off a hamlet, and on we trudged through the thickening dusk. Once, where the sand-bags were lower than I had noticed, I thought some very small bird had chirped behind my head, until the other man turned his and smiled. 'Hear that?' he said. 'That was a bullet! It's just about where they sniped at _me_ this morning.' I shortened my stick, and crept the rest of the way like the oldest inhabitant of those trenches, as perhaps I was. CASUALTIES It was nearly dark when our journey ended at one of those sunken roads which make a name for themselves on all battle-fields, and duly complicate the Western Front. Sometimes they cut the trench as a level crossing does a street, and then it is not a bad rule to cross as though a train were coming. Sometimes it is the trench that intersects the sunken road; this happened here. We squeezed through a gap in the sand-bags, a gap exactly like a stile in a stone fence, and from our feet the bleak road rose with a wild effect into the wintry sunset. It was a road of some breadth, but all crinkled and misshapen in its soiled bandage of frozen snow. Palpable shell-holes met a touchy eye for them on every side; one, as clean-cut as our present footprints, literally adjoined a little low sand-bagged shelter, of much the same dimensions as a blackfellow's gunyah in the bush. This inviting habitation served as annex to a small enough hut at least three times its size; the two cowered end to end against the sunken roadside, each roof a bit of bank-top in more than camouflage, with real grass doing its best to grow in real sods. 'No,' said the other man, 'only the second half of the hut's our hut. This first half's a gum-boot store. The sand-bagged hutch at the end of all things is where we sleep.' The three floors were sunk considerably below the level of the road, and a sunken track of duck-boards outside the semi-detached huts was like the bottom of a baby trench. We looked into our end; it was colder and darker than the open air, but cubes of packing-case and a capacious boiler took stark shape in the gloom.
