And then, as always in Mexico, the unexpected happened.

The silence was punctured by the staccato roar of a machine-gun!

In an instant all was confusion.

Whether or not the shooting came from the Carranzista escort or from some gang of bandits hidden in the brush, no one waited to ascertain. Not a person screamed. Yet, as though trained by previous experience, every one ducked beneath the level of the windows, the women sheltering their children, the men whipping out their long, pearl-handled revolvers. The only man who showed any sign of agitation was my portly friend. His immense purple sombrero had tumbled over the back-rest onto another seat, and he was frantic until he recovered it.

After the first roar of the machine-gun, all was quiet. The fatalistic calm of the Mexicans served only to heighten the suspense. The train had stopped. When, a few months earlier, Yaqui Indians had raided another express on this same line, the guard had cut loose with the engine, leaving the passengers to their Fate—a Fate somewhat gruesomely advertised by a few scraps of rotted clothing half-embedded in the desert sand. The thought that history had repeated itself was uppermost in my mind, and the peon on the floor beside me voiced it also, in a fatalistic muttering of:

Dios! They have left us! We are so good as dead!”

We waited grimly—waited interminably. With a crash, the door opened. A dozen revolvers covered the man who entered. A dozen fingers tightened upon a trigger. But it was only the conductor.

No hay cuidado, señores,” he said pleasantly. “The escort was shooting at a jack-rabbit.”
