CHAPTER XIII.
CROSSING THE FORD.
"Whee! hunt cover, fellers! Somebody's making a target of us!" exclaimed Tubby, looking wildly around for a convenient tree or adobe hut behind which he might hide his ample form.
But the Mexican guide showed them how they could quickly find shelter back of the bank; and, possibly, all of the boys breathed easier when assured that they were no longer exposed to the fire of the unseen marksman far back on the other side of the narrow river.
"But what does it mean?" asked Rob. "I thought the rebels were in force across the bridge, and that they did all in their power to make Uncle Sam look on their side with favor."
"It is so, young señor," the guide replied; "but often have the bullets come across here when the Federals and the rebels, they have fight it out over there. But now it is that some man thinks if Americans are shot it must come that the soldiers in El Paso will have to cross the international bridge, and that would mean what they call intervention."
"Oh! I see what you mean," Rob told him. "Then that was only some crazy man with a gun who wanted to bother Uncle Sam and make him real mad so he would send his soldiers across to punish him. And once they stepped on Mexican soil it would mean we'd have a war on our hands."
After that they were careful not to expose themselves more than seemed necessary as they continued their walk; and coming back they kept further away from the river so as to avoid a repetition of the bombardment. There was not much chance of the wretched marksman hitting them; but then, even bullets fired at random have been known to find a lodging place, as Rob had been told.
One of the first things the guide had assured them was that it would never do for the scouts to think of trying to enter Mexico by openly crossing the bridge. It was closely guarded on the one side by Uncle Sam's soldiers, and across the line by squads of rebels. The latter examined every one wishing to come or go, in many cases forcibly preventing the exit of some promising subject who might be made to yield tribute to the cause of the revolutionists, as well as refusing to allow others to enter Mexico, whom they believed might have some object contrary to the interests of their side.
But then the guide had informed them that he knew a ford where they might with perfect safety cross the river, now at a low stage. Once on the opposite shore they must depend on the fleet heels of their horses to take them inland, and in this manner avoid a meeting with any hostile force.
