If only----

Stuart thumped on the ground in his excitement.

Why could he not stain his skin coffee-color, like a Haitian boy? If sufficiently ragged, he might be able to pa.s.s without suspicion. It might be only for a day or two, for Stuart was sure that his father would appear again on the scene very soon.

This much, at least, he had decided. No one was going to plot against his country if he could help it. There was not much that he could do, but at least he could shadow one of the conspirators, and what he found out might be useful to his father.

This determination reached, the boy hunted for some wild fruit to stay his appet.i.te--he had nothing to eat since the night before--and settled down for the rest of the afternoon to try and dig out the meaning of his father's papers, some of which seemed so clear, while to others he had no clew. It was characteristic of the boy that, once this idea of menace to the United States had got into his head, the thought of personal danger never crossed his mind. The slightly built boy, small even for his age, the first sight of whom would have suggested a serious high-school student rather than a sleuth, possessed the cool ferocity of a ferret when that one love--his love of country--was aroused.

His first step was clear. As soon as it was dark enough to cover his movements, he would go to the house of one of his father's friends, a little place built among the ruins of Cap Haitien, where they had stayed two or three times before. From references in some of the letters, Stuart gathered that his father had confidence in this man, though he was a Haitian negro.

As soon as the shadows grew deep enough, Stuart made his way through the half-grown jungle foliage--the place had been a prosperous plantation during French occupation--and, a couple of hours later, using by-paths and avoiding the town, he came to this negro's house. He tapped at the same window on which his father had tapped, when they had come to Cap Haitien a week or so before, and Leon, the negro, opened the door.

"But, it is you, Yes!" he cried, using the Haitian idiom with its perpetual recurrence of "Yes" and "No," and went on, "and where is Monsieur your father?"

"I don't know," answered Stuart, speaking in English, which he knew Leon understood, though he did not speak it. "I have missed him."

"But where, and but how?" queried Leon, suddenly greatly excited. "Was he already going up to the Citadel?"

Stuart's face flushed with reflected excitement, but his eyes held the negro's steadily. Leon knew more than the boy had expected he would know.

"No," he replied, "I don't think so. I shall have to go."

"It is impossible, impossible, Yes!" cried Leon, throwing up his hands in protest. "I told Monsieur your father that it was impossible for him.

And for you----"

A graphic shrug completed the sentence.

Stuart felt a sinking at the pit of his stomach, for he was no braver than most boys. But the twist of his determination held him up.

"Leon," he said, trying to keep his voice steady, though he felt it sounded a little choked, "isn't there the juice of some root which will turn the skin brown, nearly black?"

"But, Yes, the plavac root."

The Haitian peered at the boy.

"You would make yourself a black man?" he continued.

Stuart ignored argument.

"Can you get some? Tonight? Right away?"

"Ah, well; you know--" Leon began.

The boy interrupted him sharply.

"If my father told you to get some, you would get it," he declared peremptorily.

This was a shrewd guess, for, as a matter of fact, there were a number of reasons why Leon should do what Mr. Garfield told him. The negro, who had no means of finding how much or how little the boy knew, shrugged his shoulders hugely, and, with a word of comment, left the house, carrying a lantern. He was back in half an hour with a handful of small plants, having long fibrous roots. These he cut off, placed in a pot, covering them with water, and set the pot on the stove over a slow fire.

"It will not come off the skin as easily as it goes on, No!" he warned.

"Time enough to think about that when I want to take it off," came the boy's reply.

The decoction ready, Leon rubbed it in thoroughly into Stuart's skin. It p.r.i.c.kled and smarted a good deal at first, but this feeling of discomfort soon pa.s.sed away.

"It won't rub off?" queried Stuart.

Leon permitted himself a grim pleasantry.

"Not against a grindstone!"

This positive a.s.sertion was as rea.s.suring in one way as it was disquieting in another. Stuart did not want to remain colored for an indefinite period of time. In his heart of hearts he began to wonder if he had not acted a little more hastily, and that if he had asked for Leon's advice instead of ordering him around, he might have found some milder stain. But it was too late to repent or retract now. His skin was a rich coffee brown from head to foot, and his dark eyes and black hair did not give his disguise the lie.

"I'm going to bed," he next announced, "and I want some ragged boy's clothes by morning, Leon. Very ragged. Also an old pair of boots."

"That is not good," protested the Haitian, "every boy here goes barefoot, Yes!"

Stuart was taken aback. This difficulty had not occurred to him. It was true. Not only the boys, but practically nine men out of ten in Haiti go barefoot. This Stuart could not do. Accustomed to wearing shoes, he would cut his feet on the stones at every step he took on the roads, or run thorns into them every step he took in the open country.

"I must have boots," he declared, "but old ones. Those I've been wearing," he nodded to where they lay on the floor--for this conversation was carried on with the boy wearing nothing but his new brown skin--"would give me away at once."

"I will try and get them," answered Leon. His good-humored mouth opened in a wide smile. "Name of a Serpent!" he e.j.a.c.u.l.a.t.ed, "but you are the image of the son of my half-sister!"

At which saying, perhaps Stuart ought to have been flattered, since it evidenced the success of his disguise. But, being American, it ruffled him to be told he resembled a negro.

He went to bed, far from pleased with himself and rather convinced that he had been hasty. Yet his last waking thought, if it had been put into words, would have been:

"It's the right thing to do, and I'm going through with it!"

CHAPTER II

WHERE BLACK MEN RULE

Stuart was not the only person on the streets of Cap Haitien the next morning who was conscious of personal danger. Manuel Polliovo was ill at ease. Bearing the secret that he bore, the Cuban knew that a hint of it would bring him instant death, or, if the authorities had time to intervene, incarceration in a Haitian prison, a fate sometimes worse than death. Even the dreaded presence of U. S. Marines would not hold the negro barbarians back, if they knew.

Manuel was by no means blind to his peril. He was relieved in the thought that the American, Garfield, was where he could not do him any harm, but there were other dangers. Hence he was startled and jumped nervously, on hearing a voice by his elbow.

"Do you want a guide, Senor?"

"A guide, Boy! Where to?"

The answer came clear and meaningly:

"To the Citadel of the Black Emperor!"
