With their baggage, valises, trunks, cameras, boxes of undeveloped film, other boxes to hold the exposed reels of sensitive celluloid, and many other things, the moving picture boys and Mr. Alcando went aboard the government tug Nama the next morning. With the exception of some Army engineers making a trip of inspection, they were the only passengers.

"Well, are you all ready, boys?" asked the captain, for he had been instructed by his superiors to show every courtesy and attention to our heroes. In a sense they were working for Uncle Sam.

"All ready," answered Blake.

"Then we'll start," was the reply. "I guess—"

"Oh, one moment, I beg of you!" cried Mr. Alcando. "I see a friend coming with a message to me," and he pointed along the pier, where the tug was tied. Coming on the run was a man who bore every appearance of being a Spaniard.

"You are late," complained Mr. Alcando, as the runner handed him a letter. "You almost delayed my good friend, the captain of this tug."

"I could not help it," was the answer. "I did not receive it myself until a few minutes ago. It came by cable. So you are off?"

"We are off!" answered Mr. Alcando.
