"No," Hal answered. "But I guess a cargo got across all right. We got this boat, and a lot of cases on board, but the cases have been carted up to camp. If the cases have been opened yet I haven't heard what they contained."

"Arms or ammunition, or both, undoubtedly," nodded Lieutenant Holmes. "The Mexicans would hardly go to the trouble of sending a cargo of anything else out in the dead of night."

"Yes; I imagine they were arms, but I don't want to say so. Captain Foster did find war supplies in two of the cases that he opened, I ought to add. But I guess I've been rattled by meeting you two so unexpectedly."

"Getting rattled is a highly unmilitary form of conduct," retorted Prescott, with a look of mock sternness.

While the young officers were still at the table Captain Foster boarded and entered the cabin.

"Keep your seats, gentlemen," directed Captain Foster, throwing himself into a corner seat. "I've just eaten. Mr. Overton, your present detachment will march ashore presently, when a sergeant and nine men relieve them here. The two companies of the Thirty-fourth are to watch the water front to the west of us. When you go on the water to-night you'll carry officers and men from both regiments. If you have to land anywhere within the territory guarded by the Thirty-seventh, Mr. Overton, you'll be in command. If within the territory of the Thirty-fourth Mr. Prescott is detailed by Captain Cortland to command on landing. While pursuing on the water, Mr. Overton, you will be in command at all times, as our regiment is furnishing the boat. Mr. Terry will accompany you also."

"There's a Navy officer, Ensign Darrin, who was visiting at Fort Clowdry, and who accompanied us, sir," announced Lieutenant Prescott. "Mr. Darrin stopped up in the village for supper and to send a telegram or two. If Mr. Darrin reaches us here in time, sir, I request permission to take him on board as a passenger."

"Who's taking my name in vain?" demanded a hearty voice from the cabin doorway.

Ensign Dave Darrin, U. S. N., as fine a looking young naval officer as ever trod bridge or quarter-dock, stood looking in.

"Come in, Darrin," cried Prescott, leaping up and moving forward. "Captain Foster, permit me to present Mr. Darrin, of the Navy."
