"Did they tell you who gave them the drink?" asked Ned.

"Yes; they said it was the fourth man."

"And there you are!" the Captain roared. "The fourth man! It is a wonder he didn't stick a knife into them!"

"How old were the men with the Lieutenant?" asked Ned. "You said they were young fellows."

"Well, they were tall and stoutish, but they looked young. Anywhere from sixteen to twenty, I should say."

"Did you notice a locked box in the party?"

"No; they carried nothing of the kind."

"They carried some baggage?"

"Yes; one suitcase. Came away in a hurry, they said. I saw the suitcase opened, on the table in there, and there was no box."

Ned took a thin, flat steel key from his pocket and held it out to the Captain. It was a key of peculiar construction, evidently made of individual pattern. In fact, it was such a key as usually goes with a strong cash box, having no duplicate.

"This was not used to open the suitcase?" he asked.

"Certainly not," was the reply. "Where did you find that?"

"On the river bank, where the canoe the men came in was beached," was the reply.

"Well," observed the Captain, "if we can't learn why they went away, or how, we may at least be able to discover where they went. Let us be about it."

"Unfortunately," Ned replied, "we can't track them through the waters of the channel. Water shows no footprints!"

"But they might not have gone away by water," insisted the other. "If they had, they would have taken the motor boat."

"They did send a man to get it," Ned replied, "but he couldn't operate it. That is why it was out of order this morning."

"How do you know that?"

"The man used matches there--the same kind of matches used in that room."

"Some day," laughed Jimmie, "some guy will come here an' move the bloomm' place away without bein' caught at it. Why didn't some one wake up?"

"I didn't wake up," said the Captain, "but that is no proof that others did not. You can't trust these Filipinos. The people of the pueblo might have helped them away."

"Exactly!" said Ned.

"If they left in a canoe," Frank suggested, "we may be able to overtake them."

"In this maze of islands!" cried the Captain. "I should say not."

"We'll get a ride anyway," Jimmie observed.

"If you'll tell Jack to get the _Manhattan_ ready," Ned said, "we'll take a run out toward that rough-looking bit of land over there toward the coast of China."

The boy darted away, and Ned directed the Captain's steps to the spot where the canoe had been beached. After inspecting the thickets into which the canoe had been drawn when taken from the water, the two, Ned in the lead, pressed through the tangle which lined the bank until they came to a clear s.p.a.ce strewn with food tins which had the appearance of having been opened within a few hours.

"They waited here," he said, "and ate while they waited. I found the key here, and not at the point where the boat was pulled from the river. The box to which it belongs was opened here and new papers put into it. At least some papers which it had contained were removed. They were burned one by one in that thicket ahead."

The Captain looked Ned over from head to foot and laughed.

"My boy," he said, "you surely know what your eyes were given to you for. Can you tell by looking at my coat how much money I have in the pocketbook in the breast pocket?"

"Hardly," laughed Ned, "but I can tell by looking at that light coat you have on that you went to sleep in your chair last night, with the lower part wrinkled up under you! Did you sleep that way all night? Own up, now!"

Captain G.o.dwin blushed through his coat of tan like a schoolgirl.

"To tell you the truth," he said, "I did sleep in my clothes last night.

After I left the Lieutenant at the hut I went home and mixed a little drink and sat down to read a bit. Well, sir, I fell asleep!"

"And woke up at daylight?" asked Ned.

"Pretty close to it," was the reply. "I awoke with a headache, too!"

"You mixed the drink yourself?" asked the boy.

"Yes; I always do."

"But your servant brought the gla.s.s?"

"Why, yes."

"Have you seen the servant to-day?"

"Sure! He got my early breakfast. We have two here, you know."

"Ever sleep like that before?"

"Not here."

Ned looked serious. This was something new. The Captain had without doubt been drugged, but who had contrived the thing?

"What are you getting at?" demanded Captain G.o.dwin. "You don't think I was doped, do you?"

"Looks like it," was the reply.

"Then the whole native population is up to something!" shouted the Captain. "I've noticed a good deal of whispering lately. Do you think the tribe on the island has gone over to the insurrectos?"

"I don't know," Ned said, "but it seems to me that something is going to happen here before long."

"I'll watch out," declared the Captain.

"How long have you been in charge here?" asked the boy.
