Useless, of course, it was, bothering to destroy a bridge in such a state; so we drew off quietly (not to alarm the workmen) walking over loose stones which turned under our bare feet in a way imposing care if we would avoid risk of sprain. Once I put my foot on something moving, soft and cold; and stepped heavily, on chance it was a snake; but no harm followed. The brilliant stars cast about us a false light, not illumination, but rather a transparency of air lengthening slightly the shadow below each stone, and making a difficult greyness of the ground.
We decided to go further north, towards Minifir, where Zaal thought the land propitious for mining a train. A train would be better than a bridge, for our need was political, to make the Turks think that our main body was at Azrak in Sirhan, fifty miles away to the east. We came out on a flat plain, crossed by a very occasional shallow bed of fine shingle. Over this we were going easily when we heard a long rumble. We pricked ears, wondering: and there came out of the north a dancing plume of flame bent low by the wind of its speed. It seemed to light us, extending its fire-tagged curtain of smoke over our heads, so near were we to the railway; and we shrank back while the train rushed on. Two minutes’ warning and I would have blown its locomotive into scrap.
Afterwards our march was quiet till the dawn, when we found ourselves riding up a narrow valley. At its head was a sharp turn to the left, into an amphitheatre of rock where the hill went up by step after step of broken cliff to a crest on which stood a massive cairn. Zaal said the railway was visible thence, and if this were true the place was an ideal ambush, for the camels could be herded without any guardians into the pit of excellent pasture.
I climbed at once to the cairn, the ruin of an Arab watchtower of the Christian period, commanding a most gracious view of rich pastoral uplands beyond the line, which ran round the foot of our slope in a lazy curve, open to sight for perhaps five miles. Below on our left was the
