"Hard to tell, sir. If we win, as we shall, the enemy may fall back toward Santa Lucrecia, or they may retreat toward Moreno. If you will take my advice, you will halt here until the action is over."

The advice seemed most excellent and the cavalcade came to a halt and the riders dismounted to give themselves a much-needed rest.

The firing lasted something like twenty minutes, then suddenly ceased, with the exception of an occasional "Boom!"

"It sounds as though we had beaten them off," said the corporal.

"Is there any way that we can tell in which direction they have retreated?"

"Only by a reconnoiter."

"Which is our long suit," declared Billie. "You just stay here with the guard, Mr. Black, and we three will soon have a report."

Looking to their arms, with which they had been well supplied by their host before leaving the hacienda, the boys rode forward toward an elevation something like a mile distant. From this they hoped to get a view of the country.

There was a fairly level road and they dashed along at a good rate despite their long ride. The horses were as hard as iron and the boys did not know the meaning of the word tired.

Reaching the top of the hill, they found a space, from which they could see clear across the valley through which ran the railroad from Santa Lucrecia to Vera Cruz. To the right, some miles away, they could see a good-sized little city which their common sense told them must be Tierra Blanca. To the left, but nearer, was the smaller town of Moreno, for which they were headed.
