My pupils practised the art of mining afterwards by themselves, and taught others. Rumour of their fortune rolled about the tribes in a growing wave: not always intelligently. “Send us a lurens and we will blow up trains with it,” wrote the Beni Atiyeh to Feisal. He lent them Saad, a cut-and-thrust Ageyli, by whose help they got an important train carrying Suleiman Rifada, our old nuisance of Wejh, with twenty thousand pounds in gold, and precious trophies. Saad repeated history by saving only the wire for his share.

In the next four months our experts from Akaba destroyed seventeen locomotives. Travelling became an uncertain terror for the enemy. At Damascus people scrambled for the back seats in trains, even paid extra for them. The engine-drivers struck. Civilian traffic nearly ceased; and we extended our threat to Aleppo by the mere posting a notice one night on Damascus Town Hall, that good Arabs would henceforward travel by the Syrian railway at their own risk.
