"Yes," he laughed; "I feel like celebrating, and I have a little scheme."

"What is it?"

"Why can't we make up a party to visit Niagara and St. Louis."

"Oh, splendid!" cried Inza eagerly.

"Then you like the idea, sweetheart?"

"I think it grand!"

"And Elsie----"

"I'm sure she'll be in for it. Although she has not said much, I know she dislikes to have Bart go away."

"Then we'll carry out my plan. You may accompany us as far as St.

Louis--perhaps farther."

Inza bubbled with pleasure over this plan, beginning at once to talk of the fine times they would have.

A closed carriage was pa.s.sing them, going somewhat faster, in the same direction.

Happening to glance toward the window of this carriage, Inza suddenly uttered a low cry and grasped Merry's coat sleeve.

"Look look!" she exclaimed.

"What is it?"

"That man!"

"Where?"

"In that carriage. He was looking from the window, but he has leaned back now. I looked straight into his eyes, and it gave me a fearful shock, for they seemed to be the eyes of Porfias del Norte!"

"How did the man look?"

"He had a strange face that was deeply lined, and his hair was very white."

"Alvarez Lazaro!" thought Merry. "The self-styled avenger is seeking his opportunity."

Having driven in the park for some time, they finally halted at a little restaurant, a man appearing to take charge of their horses.

Near at hand a man was stretched on the ground beneath an automobile, engaged in tinkering at it.

Merry was about to enter the building with Inza when another man appeared, approached the one who was working at the automobile, and impatiently questioned him in regard to the progress he was making.

"There is Mr. Hatch," said Frank. "I'll speak to him. I'll join you inside in a few moments, Inza."

He turned back and approached Warren Hatch, who was standing and frowningly watching the efforts of the one who was tinkering at the automobile.

"Good morning, Mr. Hatch," said Merry.

The face of Hatch cleared a little, and he shook hands with Frank.

"Glad to see you, Merriwell. Did you just drive up? Should have been away from here thirty minutes ago, but something happened to this old machine, and Casimer is having a d.i.c.kens of a time fixing it. I've been to see Scott."

"How is he?"

"A sick man--a mighty sick man."

"What is the matter?"

"That's the queer thing about it. Doctor hasn't told. Don't believe he knows."

"It is rather queer."

"First the doctor fancied it might be something like paralysis or apoplexy; but it's not. You know Scott was taken while dining at the Waldorf with a man who claims to be interested in the Central Sonora project and expresses a desire to take on one thousand shares of the stock."

"I didn't know about that."

"Yes. I talked with Scott. He's weak and almost helpless. Can barely wiggle a finger, but he can talk, and his mind is not affected."

"Why, the paper said he was very comfortable this morning."

"He may be; but I'd rather see him more frisky."

"You do not apprehend a serious termination?"

"I hope not. Scott has a const.i.tution like iron, and he won't die easily. Still, I shall be worried if he shows no signs of improvement to-day. Do you know, he told me that the man he dined with last night was a Mexican. I haven't much use for them. Found one here talking to Casimer a short time ago--a fellow with the whitest hair I've ever seen."

Frank started.

"I believe I've seen that man," he said. "He pa.s.sed us in the park."

"He was parley vooing with Casimer and bothering him," said Hatch. "I politely informed him that I was in a hurry, and asked him not to bother my chauffeur. Say, he turned and looked at me with a pair of black eyes that seemed as dangerous as loaded pistols. 'I beg your pardon, senor,'

he purred. 'If I have bothered your chauffeur or delayed you in the least, I am very sorry. I trust you may get started soon and meet with no more serious accident to-day than this little breakdown.' I swear there was something in his manner so offensive that I felt like hitting him, and yet he was the very soul of politeness."

Frank nodded, and Hatch noted a singular expression on the face of the youth.

"What are you thinking of?" he inquired. "Something is running through your head."

"It is. Did you ask Mr. Scott the name of the man with whom he dined last evening."

"Yes."

"It was----"

"Alvarez Lazaro."
