We could see the American line checked as with the buffet of a great wave, men and horses rolling in the road. Through the smoke one saw the grey-haired leader —dismounted, his uniform torn, his hat gone, but still brandishing his sword and calling his orders to his men, his face as one caught in a flash of sunlight, steady and fearless. His words I could not hear, but one saw the American cavalry, still unbroken, dismount, throw themselves behind their horses, and fire with steady aim into the mass of the Mexicans. We could see the Mexicans in front of where we stood falling thick and fast, in little huddled bundles of colour, kicking the sand. The man Pete had gone down right in the foreground and was breathing out his soul before our eyes.

"Well done," I shouted. "Go to it, boys! You can lick 'em yet! Hurrah for the United States. Look, Raymon, look! They've shot down the crew of the machine guns. See, see, the Mexicans are turning to run. At 'em, boys! They're waving the American flag! There it is in all the thick of the smoke! Hark! There's the bugle call to mount again! They're going to charge again! Here they come!"

As the American cavalry came tearing forward, the Mexicans leaped from their places with gestures of mingled rage and terror as if about to break and run.

The battle, had it continued, could have but one end.

But at this moment we heard from the town behind us the long sustained note of a steam whistle blowing the hour of noon.

In an instant the firing ceased.

The battle stopped. The Mexicans picked themselves up off the ground and began brushing off the dust from their black velvet jackets. The American cavalry reined in their horses. Dead Pete came to life. General Villa and the American leader and a number of others strolled over towards the boss, who stood beside the fence vociferating his comments.

"That won't do!" he was shouting. "That won't do! Where in blazes was that infernal Sister of Mercy? Miss Jenkinson!" and he called to a tall girl, whom I now noticed for the first time among the crowd, wearing a sort of khaki costume and a short skirt and carrying a water bottle in a strap. "You never got into the picture at all. I want you right in there among the horses, under their feet."

"Land sakes!" said the Sister of Mercy. "You ain't no right to ask me to go in there among them horses and be trampled."

"Ain't you paid to be trampled?" said the manager angrily. Then as he caught sight of Villa he broke off and said: "Frank, you boys done fine. It's going to be a good act, all right. But it ain't just got the right amount of ginger in it yet. We'll try her over once again, anyway."
