Presently two soldiers came down, halting in the cabin doorway.

"We are ready, sir," spoke one of them.

"Ready for what?" jeered the stranger. "Have you come to shoot me?"

"We're nearing the dock at Agua Dulce, sir, and the lieutenant sent us to get you and make sure that you don't try to escape."

"I'll be bound that you won't give me any chance to get away," jeered the fellow.

"No, sir," answered the soldier gravely.

The Mexican helmsman proved that he was no mean boat-handler. He ran in alongside the dock, making nearly as fine a landing as Skipper Tom Halstead himself could have done. Lieutenant Hal waited only long enough for Corporal Shimple to send over two men from the tug in a row-boat to stand guard over the motor boat prize. Then, with his own boat squad, and leaving behind only the dead and the wounded Mexican, the Army boy marched his prisoners by a route that led around the village instead of through it.

Captain Foster had lain down, fully dressed, prepared to be called at any moment. He now came forth from his tent. He heard Lieutenant Hal's brief report with few interruptions.

"Your name, sir?" demanded Foster, turning to the purple-faced one.

"James D. Ruggles," came the surly answer.

"I hope you are giving your correct name."

[Ill.u.s.tration: "That's the Money!"]

"Why shouldn't I? If I gave you a wrong name there are plenty of people hereabouts who could soon set you straight."

"Your business, Mr. Ruggles?"

"Owner of mines in Mexico."

"Any in the _insurrecto_ district?" pursued Captain Foster.

"Yes. That's why----"

Ruggles checked himself suddenly.

"You are not required to confess or incriminate yourself, unless you want to," Captain Foster advised the prisoner. "However, I imagine that the cargo of the boat and your actions to-night will furnish all the evidence against you that are needed. Mr. Ruggles, I shall have to hold you and your Mexican companions until I am advised what to do with you.

There is no charge against your daughter. She may go to the hotel in Agua Dulce, if you wish. I will see to it that she is properly escorted."

"If you will be so good, Captain," answered Ruggles huskily. "But where shall I sleep to-night?"

"On a cot in the guard-tent, sir. I am sorry, but that is the best that we can do."

Meta Ruggles began to weep softly over her father's trouble and disgrace. Sergeant Raney, therefore, escorted her from camp as soon as he could persuade her to start for the village. Raney was also directed to send an undertaker for the body of the dead Mexican, and a local physician to look after the wounded one.

"You are going to sit here for a while, Captain?" inquired Ruggles.

"I think I shall."

"Then may I sit with you a few minutes before I am marched off to the guard-tent?"

"Certainly."

Hal had stepped into the tent shared in common by the officers. Ruggles, who had bitten the end from a cigar and had lighted the weed, now leaned over to whisper to Captain Foster:

"Has the young man had chance to give you a word or two of explanation yet?"

"What young man?" demanded Captain Foster, turning to look at Ruggles.

"Why, the officer who marched us over here."

"Lieutenant Overton?"

"Certainly. Has he told you anything? I mean about how this whole business is to be fixed so as to keep me out of it altogether?"

"What on earth are you talking about?" demanded Captain Foster, who was now wondering whether his ears had played him a trick.

"Why, it's all settled," murmured Ruggles.

"I turned the money over to your chap, Overton, and he told me it would be all fixed. I'm not to be held or prosecuted in this matter. The trouble is all to fall on the Mexicans."

"I wish I knew what you were talking about," cried Captain Foster.

"Why, it's plain enough, Captain. I paid the money over to your lieutenant, and he and you were to fix it so I could slide out of the matter and keep my name out, too. I paid Overton the five thousand dollars, which he said would be enough for you both and that it would be all right."

"Mr. Overton!" called Captain Foster gasping.

But Hal did not have to be summoned. He had heard Ruggles's last statement from the doorway of the officers' tent.

"Here I am, sir," cried Lieutenant Hal, coming forward, "and I overheard that lying hound! What this fellow, Ruggles, is telling you, Captain, is wholly false."

"I know it, Overton, I know it," cried Captain Foster, who had sprung to his feet.

"Am I to be flimflammed, after paying the money in good faith?" demanded Ruggles. "See here, Captain, I drew twenty thousand dollars, in twenty bills, at the bank this afternoon. That I can easily prove, of course.

Nor can any one on earth prove that I have spent any of that money, for, as it happens, I had the cashier at the bank take the numbers of the thousand-dollar bills. In this envelope, sir, you will find fifteen of the bills left. The numbers of the missing bills can be proved, and the missing bills you will find in the possession of your lieutenant."

"It's a cowardly lie!" blazed thunderstruck Hal, leaping forward. But Captain Foster pushed him gently back.

"I haven't a doubt that it's a lie, Overton, my boy," replied Foster.

"Yet don't get too excited, or try to use violence on your accuser.

Remember that I am simply bound to hear any complaint that may be preferred against any officer in my command. Be cool, Overton, and be sure that no harm can come to you if you are innocent, as I am certain that you are. Here is your envelope, Mr. Ruggles. I have looked over the contents, which are, as you state, fifteen one-thousand-dollar bills."

"And the other bills you will find on this lieutenant. Though, wait a moment. He has just been in his tent. He may have hidden the money there."

"If it's true that you handed this lieutenant money, Mr. Ruggles, what did he do with it when he first received it?" asked Foster.

"I don't know, Captain, except that he went forward into the stateroom to look it over. He didn't have it in his hand when he came out of the stateroom."

"You----" quivered Hal.
