Disregarding the lordly disposal of the yacht and its contents so coolly outlined by SeÑor Ramon Ganza, those aboard the Salvador began to face the probability of a siege. They all gathered aft, where, shielded by the bulwarks from the view of the Mexicans, they could converse at leisure and with safety. At Madeline's suggestion, every member of the crew, seven in number, was present while the details of their visit to the larger island were related by his principals. The character of the lordly islander, and his history as gleaned from Pietro and Chica, were likewise canvassed, and his evident intention to add the strangers to his band of cowed subjects was impressed upon the entire company in a most forcible manner.

"It would have been serious, indeed," continued Madeline, "had Ganza arrived here before us and found you unwarned and unarmed, for you could not have resisted his invasion. But his clever scheme was frustrated by an accident to the engines of his launch, and now we must bend our every energy to driving him away and making our escape from this dreadful island."

"We don't know yet, of course, how that can be done," added Mr. Radley-Todd, reflectively; "but there's no hurry about deciding it. We are pretty well provisioned for a siege, and Steve and I captured from the enemy and brought with us nine rifles, half a dozen revolvers, and some ammunition."

"We have also a small supply of arms and ammunition in the storeroom of the yacht," said Captain Krell. "The former owner was something of a sportsman, and I think you will find the guns to be shotguns."

"All the better," said Chesty. "These fellows may decide to board us, in which case the shotguns, at short range, will scatter their loads and do fearful execution. Get 'em up, Captain. Let's have on deck, where it's handy, every offensive and defensive weapon aboard."

"I don't want any shooting," protested Madeline; "I'd rather give them the yacht."

"We won't need to shoot," returned Steve. "A big bluff is all that is necessary."

The entire company now understood the importance of a successful resistance, and aside from the fact that Mrs. Tupper had violent hysterics, which lasted several hours and nearly caused her devoted husband to jump overboard, the situation was accepted by all with philosophical composure. A definite plan to guard the deck and prevent the foe from scaling the sides was adopted and each man given his position and instructed what to do.

As they were dealing with a desperate and unscrupulous man, a self-constituted autocrat in this practically unknown group of islands, they realized the wisdom of being constantly alert; so all the men, passengers and crew alike, were divided into watches during every hour of day and night, and those not on duty slept in their clothing that they might respond instantly to any call to action.

The Mexican, however, proceeded very deliberately with the siege, believing his victims were trapped and unable to escape him. He withdrew for a time around the rocky point, where he disembarked ten of his fourteen men. With the other four he ran the launch to the mouth of the bay again and dropped anchor, evidently intending to block any egress by the boats of the yacht.

That night, under cover of the darkness, for the moon was often obscured by shifting clouds, Ramon's men deployed among the rocks on both sides of the narrow channel, where they erected two miniature forts, or lookouts, by piling up the loose rocks. Behind each rock barrier some of the men were stationed, with instructions to watch every movement on the deck of the Salvador and report to their master. The Mexicans were well protected by the rocks from the firearms of those on board, if the defenders resorted to their use, and because of the slant of the deck from fore to aft Ramon could himself command almost the entire deck as he sat in his launch.

Realizing this disadvantage, Radley-Todd and O'Reilly, the engineer, crept down to the stern and by pushing the ends of their rifles through the hawser-holes were able to bring the launch under such direct fire that the outlaw decided that discretion was the better part of valor and withdrew his boat to a safer anchorage around the point, where he might still intercept the passage of any boat that ventured to come out.

The next morning Francisco of the one eye and a comrade took the launch back to the other island for a store of provisions. When they returned, at noon, they brought the two men who had been left behind when the first expedition set out, and also one of the rowboats, which was allowed to trail behind the launch.

With the Americans surrounded and on the defensive Ramon felt that he could safely remove his entire force from his home island and leave the place to the keeping of the women. If it came to a fight he would need every man he had.

On that first day those on the yacht were alert and excited, but the marked composure on the part of their besiegers gradually quieted their fears of immediate violence. The decks were not really dangerous, although constantly under the observation of the men in the rock fortresses, so they ventured to use them freely. At one time, when Chesty Todd made a feint of landing on the shore, a group of Mexicans quickly gathered to prevent his leaving the ship, thus demonstrating their open enmity.

"This won't do!" declared Steve, savagely, as he faced the company assembled around the cabin table that evening. "Those infernal bandits mean to keep us here till doomsday—or until we go crazy and surrender. They'll make our lives miserable unless we dislodge them from those rocks."

"I prefer them there to having them attempt to scale the sides of our ship," returned Chesty. "A hand-to-hand fight would be far more serious."

"Interesting, isn't it?" said Mr. Cumberford.

"I don't think they care for a hand-to-hand fight," observed the captain. "Such fellows as this Ramon Ganza are always cowards."

"I don't know about that," said Madeline. "He has faced all the men he brought here and in spite of their numbers and their hatred of him has cowed them, every one, single-handed."

"Ramon is not a coward," the child Chica declared very positively. "He is bad; yes. But not a coward."

"He has sixteen men—with himself, seventeen—and we have but eleven," said Steve. "However, the advantage is with us, because the yacht is a fort."

"You spoke a moment ago of dislodging them," remarked Radley-Todd. "Can't we manage to do that, Steve?"

"How?"

"If we could make some bombs," suggested the press-agent, slowly, "and hurl them among those rocks, I've an idea we could drive them away."

Steve was thoughtful a moment.

"We'd need nitro-glycerine for that," said he. "I suppose there's none aboard, Captain Krell?"

The captain shook his head.

"Plenty nitro-glycerine at big islan'," announced Pietro. "Ramon use it to blast rock."

"Ah, but that's a good way off," declared Steve.

Chesty drummed on the table, musingly.

"If Pietro will go with me," he said presently, "I'll get you the nitro-glycerine."

"You're crazy, man!"

"Not quite," said Chesty, with a smile. "Every man belonging to Ramon's band is now here. I'm not afraid of the women he has left back there."

"But how will you get there—swim?"

"We'll take the launch, Pietro and I, and run the blockade at dead of night."

"No," said Madeline, with decision, "I can't allow that. It would be too dangerous an undertaking. You might be captured."

"I don't think so. If we are discovered, your launch can outrun theirs and I'll lead them a merry chase and come back again. What do you say, Pietro?"

"Who? Me, SeÑor? Why, Ramon my enemy now. So I go with you."

"You needn't fear Ramon, Pietro," said Madeline, gently. "We shall manage in some way to get you safely back to Mexico."

The man's expression was stolid and unbelieving.

"Perhaps he doesn't dare go back to Mexico," said Sybil.

"Oh, yes;" replied Pietro. "I not 'fraid of Mexico. I smuggle, sometimes, before Ramon get me; but they forget all that by now. It is Ramon I fear. He is very bad man, as little Chica say. Always he wins, never he loses, in what he tries to do. For me, I have disobey an' defy him, so Ramon he whip me sure, when he catch me, an' when Ramon whip it is as bad as to die."

It was impossible to overcome this stubborn belief in Ramon's omnipotence and they did not argue with the man further. But Orissa, who had been thoughtfully listening to the conversation, now said:

"I do not like the plan of bringing nitro-glycerine here, even if Chesty could succeed in getting it. The stuff would be dangerous to us and to our enemies, for a slight accident would explode it or careless handling might blow us all to eternity. But, admitting you made the bombs, without accident to any of our party, what would be the result of exploding them among those little rock forts yonder? Wouldn't the rocks scatter in every direction and bombard us and the ship, perhaps causing damage that would be fatal to our hopes of escape?"

"Orissa is quite right," said Mr. Cumberford, decisively. "We must abandon the idea at once."

"I know it appears a desperate measure," admitted Radley-Todd, "but something must be done, both to drive away our enemies and get the Salvador afloat again. Cut the explosives, and what remains for us to do?"

"Make a sortie and drive them away from here," replied Cumberford. "I'm a little old for a pitched battle or guerrilla warfare, but this extraordinary Mexican—er—er—interests me. I'm willing to have it out with him here and now."

"One white man is worth six Mexicans," declared Captain Krell, belligerently.

"Won't do at all," asserted Steve. "We can't afford to take the chances of defeat, gentlemen, while we have these girls in our care. The ship is a fort that is almost impregnable, and we mustn't leave it for an instant—under any circumstances."
