know what Santiago's surname is?"

"Si, senor. It is Ojeda."

"What?" cried all the boys at once. "Ojeda? Why, that was old Don
Pablo's name."

The boys stood and eyed each other in speechless wonder. The same
thought was in all their minds.

"Do you think it is possible?" asked Billie at last.

"Do I think what is possible?" asked Lieutenant Grant.

"Why, that Santiago could have given those drafts to the stranger
so as not to be known in the matter."

"Possibly. He seems a man of mystery."

"Well," declared Billie, "I am going to find out."

"How, I should like to know," asked Donald. "He's too crazy to
remember anything, even if he wanted to tell you."

"You forget Lucia," said Billie.

"Oh, no, I haven't," laughed Donald, "and I have no doubt she
would tell you all about it if she knew; but I do not believe she
does. Santiago is too deep to have entrusted his secrets to a
girl not yet out of her teens."

"You never can tell," remarked the lieutenant. "Men with a
hobby do strange things. You'd better ride along with me to
headquarters. I'd like to introduce you to General Funston. He's
a man after your own hearts. You know how he went out and
captured Aguinaldo when he was in the Philippines."

"I've read about it," replied Adrian. "It was a bold deed."

"Sure was," said Donald. "We'll be mighty glad to meet him."

It may also be said that General Funston was glad to meet the
Broncho Rider Boys, especially after Lieutenant Grant told him in
a few words of the good work they had done on the border and on
the day that Vera Cruz was taken.

"And when do you expect to return to the United States?" asked
the general.

"Just as soon as we can obtain passage," replied Donald.

"I think we can arrange that for you in a few days," replied the
general. "In the meantime come in occasionally."

The boys thanked him and started to leave, when the telephone in
the general's quarters rang. He looked for some one to answer,
but no one being at hand, he picked up the 'phone himself.

"What's that?" he asked after a brief moment. "The water works.
You think they are attempting to cut you off. All right, I'll
rush help."

He set down the 'phone and turned to Lieutenant Grant.

"The enemy has gathered in force about the water works," he said
sharply. "They evidently intend cutting off the water supply.
Tell Colonel Bright to send them reinforcements at once. Do you
boys know the way there?"

"Yes, sir,"
