"Good evening, Mr. Diaz," said Phil quickly recovering his self-possession.

Diaz uttered an unintelligible grunt, but did not deign to turn his head.

"Hey, Phil, is that you?" called the voice of Teddy from further down the deck.

"Yes," answered Phil, rising and moving aft. "How long have you been here?"

"About an hour."

"Do you know who is sitting over there?"

"Over where?"

"There by the rail?"

"Sure, I know. That's our old friend Diaz," grinned Teddy.

"How long has he been there?"

"He came in when I did."

"An hour ago?"

"Yes."

Phil was perplexed.

"I do not understand it at all."

"Don't understand what?"

"Something that occurred this evening."

Teddy's curiosity was aroused.

"What is it all about, Phil?"

"I should prefer not to talk about it here, Teddy. I will tell you after we get to bed and there is no one about to overhear us.

There is a rascally plot on foot."

"A plot?"

"Yes. I know very little about it, but I know enough to warn me that you and I will have to keep our eyes open or else we shall find ourselves in serious difficulties before we realize it."

"Is that so? Tell me who the plotters are, and I'll turn January loose on them," explained Teddy. "Do you think they are the fellows who stole my egg?"

"I don't know. Where is Mr. Sparling?"

"I haven't seen him since I ran into him and bowled him over off on the lot."

Phil laughed.

"As I have said many times before, you are hopeless, Teddy.

I must go now. If you see Mr. Sparling, please let me know, but say nothing to anyone about what I have just told you."

"I won't."

Phil walked back to the point on the deck where he had first stopped to look over the rail, and, drawing up a stool sat down.

He began studying the faces of the belated performers who came straggling down to the dock, singly and in pairs. None seemed to be in a hurry; not a face appeared to reflect any excitement.

After an hour of this Phil felt sure that all the company had been accounted for.

Mr. Sparling had arrived about twenty minutes earlier, and was standing on the dock giving orders. As the lad saw the owner enter the boat he turned away and hurried downstairs.

"When you are at liberty, I should like a few moments conversation with you, sir," announced Phil.

"I am at liberty, now, my lad," answered the showman with a smile and a friendly slap on the boy's shoulder.

"I would rather not talk here, Mr. Sparling," answered Phil in a low tone.

"Something doing, eh?"

"There is."

"Is it important that you should talk with me at once, or will a little later on answer the purpose?"

"Later on will do. It is not so urgent as that."

"When the men get these menagerie cages all shifted on deck I will meet you in my cabin. That will be in about twenty minutes, Phil."

"Very well, sir; I will be on hand."

Phil walked away, watched the loading operations for a few minutes, then strolled to the main cabin on the upper deck, where lunch was being served as usual.

The Circus Boy appeared more light-hearted than usual that evening, as he chatted and joked with his friends among the performers. He did not wish the man or men whom he had overheard off on the lot to know that he was the eavesdropper.

He felt that he could make better progress in his investigation were they not on their guard.

The pilot, c.u.mmings, was not in the cabin. He had not been seen there since his trouble with Teddy. Despite the pilot's determination to resign, he was still on duty, he and Mr. Sparling having come to a satisfactory understanding.

Teddy was helping himself liberally for the second time since his return from the lot.

"Do you think you will ever be able to satisfy that appet.i.te of yours?" laughed Phil.

"I hope not," answered Teddy solemnly. "That's the only fun in life--that and the donkey."

Just then Mr. Sparling pa.s.sed through the cabin on the way to his stateroom and office. He gave Phil a significant glance, to which the Circus Boy did not respond. A few minutes later, however, Phil strolled out to the deck. Reaching it he turned quickly and hurried aft, entering the pa.s.sageway there and going directly to Mr. Sparling's quarters.

"Come in," invited the owner in response to Phil's gentle rap.

The blinds had been drawn up, though the windows were let down into their casings out of sight. Phil noted this in a quick glance.
