"We must run it at all events;" and wishing his friend goodbye, Adair returned on board with the information he had gained.

The calm still continued; but as a breeze might at any moment spring up, Jack and he anxiously looked out for Jose. They were indeed in a hurry to recommence the ascent of the river, for the longer they delayed, the greater risk they ran of being attacked.

The sun set, and still Jose had not made his appearance. Jack was just going below when Needham came aft. No one had showed more anxiety about the midshipmen than he had.

"It has come into my mind, sir, that if the young gentlemen are anywhere hereabouts they may have caught sight of the brig, and will be trying to make their way down to the sh.o.r.e abreast of us. If you will give me leave to take the jollyboat, I will pull in and have a look for them; and even if they don't come, Jose may be wishing to get off, with any information he has picked up, though I have no great hopes that he will do much."

"I am afraid not either," said Jack, "but by all means take the boat and remain as long as it continues calm. Should a breeze spring up, you must, whether successful or not, return on board. It is my duty to proceed up the river as fast as I can, and my anxiety to recover my brother and Mr Desmond must not make me neglect that."

Needham found no difficulty in obtaining volunteers for his expedition.

They went well-armed in case any hostile natives might appear, though the country people in general showed a friendly disposition.

Jack and Terence while at their frugal supper of corn beef and biscuit, talked over a plan for protecting the men, should they be fired at as they ascended. They arranged to build a barricade of hammocks and bags to defend the helmsman on the port side while the crew were sent below, they of course intending to remain on deck.

"The fellows have not shown themselves to be good shots, and if the breeze holds we may run by them without much damage," observed Jack.

"But if the wind should fall or blow down the river?" suggested Terence.

"Then we must go about and wait for a better opportunity for running up," answered Jack. "We may try it at night and may slip by the more dangerous places without observation."

They both talked hopefully of recovering the midshipmen, and yet they could not help occasionally feeling that the youngsters might after all have lost their lives.

At last they turned in, Bevan having the watch. Though very gallant British officers, they were not heroes of romance, and therefore required sleep as much as anybody else. Jack had left directions to be called should a breeze spring up or Needham return on board. It had gone two bells in the morning watch when Norris came into the cabin and awoke Jack.

"There is a light air from the south'ard, and it has been getting stronger for the last few minutes, but the boat has not come off yet,"

he said.

Jack sprang up.

"We will make sail and stand over to the other sh.o.r.e to pick her up," he answered; "we must not delay a moment."

The anchor was hove up, and sail quickly made, the breeze rapidly increasing. She had got halfway across to the western sh.o.r.e when the boat was observed approaching and was soon alongside.

"We have seen nothing of the young gentlemen, sir, nor has the spy shown his face," said Needham. "I waited till the last moment, hoping that some one would appear. I fancied I saw people moving about on the bank, and now and then heard voices close down to the boat. We pulled some way down the river and then back again as high up as we had gone down, every now and then shouting out the young gentlemen's names, so that if they had been anywhere hereabouts they must have heard us."

Jack agreed with Needham that Tom and Gerald were not likely to be in the neighbourhood, and the boat being dropped astern, to be in readiness should they or the spy appear, the _Supplejack_ continued her course up the river. The increasing daylight enabled Jack to see his way, and of course a sharp lookout was kept on the sh.o.r.e.

The brig continued on for some distance, neither cavalry nor artillery being seen. A few foot soldiers were observed trudging along, and occasionally country people appeared on the high ground, but none of them came down to the beach.

The appearance of the banks varied considerably in different places; in some they were sloping and were covered with trees and shrubs, in others they consisted of high earthy cliffs with the open plains of the Pampas reaching to the edge of their summits. Frequently the telescope revealed projecting from the cliffs the bones of the megatherion, mastodon, milodon, and other huge antediluvian animals, of which, however, neither Jack nor Terence knew the names. Sometimes they were so distinct that they were remarked by the men, who wondered how such strange animals could have found their way there.

"They cannot have gone and buried themselves," sagaciously observed Bill Lizard, the boatswain's mate.

"For my part, howsomedever, I cannot think that anybody would have taken the trouble to bury them," answered Needham. "It's a pity we have not got Mr Scrofton on board; he would have told us all about it, no doubt."

The ship's company, however, had soon other matters to engage their attention. The brig was now approaching that part of the river where the deep channel runs under the lofty and perpendicular cliffs of San Lorenzo. The bed is as wide as in other places, but on the eastern side is a line of islands extending for several miles, and forcing the current over to the west. It was still doubtful, however, whether the enemy had observed the brig, or would venture to attack her if they had.

Terence had gone aloft to be able to get a better view over the plain, when he made out several hors.e.m.e.n, and what he at first took for carts in the far distance, but which as they emerged from a cloud of dust partially concealing them he discovered were field-pieces. There could be little doubt that the _Supplejack_ would not escape without being fired at. Fortunately there was a good stiff breeze, and under all sail she stood boldly up the clearly defined channel. The ensign was flying at the peak, and Jack ordered one to be hoisted at each masthead, to show the enemy that he intended to fight as long as the masts stood, or his vessel remained above water.

The brig had not got far, however, when six field-pieces, dragged by horses, with a considerable body of men, were seen some way ahead approaching the edge of the cliffs. Jack was not left long in doubt as to their object, for bringing their guns to bear on the brig, the Spaniards opened fire, their shot whizzing over the brig, a few only pa.s.sing through her sails.

Needham had got his beloved Long Tom elevated as much as possible, the two carronades loaded with canister, and the rockets were ready in their stands.

"Let them learn what Long Tom can do," said Jack. Needham fired but the shot flew over the heads of the enemy; the gun was quickly again loaded.

After the next shot two or three of the horses were seen plunging wildly, and one of the guns appeared to have received some damage--the distance was too great to ascertain what it was. The brig made rapid way, the next shot buried itself in the cliff; it was evident that Long Tom could do no more for the present. The carronades were now fired, and a flight of rockets sent the hors.e.m.e.n galloping out of the way, while the gunners scampered off or threw themselves on the ground; a second flight of rockets and another dose of canister kept them from returning till the brig had neared the cliffs; so close indeed was she that her mainyard almost touched them, while the enemy, who by this time had returned, could not sufficiently depress their guns to send a shot down on her decks, neither did the riflemen approach sufficiently near the edge to fire into her; probably having a wholesome dread of the rockets or bullets which might be sent in return from the daring little vessel.

As yet no one had been hit on board the brig, and Jack was beginning to hope that she might pa.s.s without damage beyond the dangerous point, when farther on appeared a line of batteries, and he had just reason to fear that they would cause him greater injury than he had hitherto received.

He pointed them out to Terence.

"I would advise you to send the hands below while you and I and the helmsman remain on deck," said Terence coolly. "We shall save the men, and should a few shots go through the ship's side we shall have time to stop the holes before much water gets in; there would be no use replying to the batteries, and we must do our best to get by them as fast as possible."

The order, which the men unwillingly obeyed, was given. s.n.a.t.c.hblock came aft to the helm, and Terence walked forward, while Jack stood at his usual post to con the brig. Needham gave a fond look at Long Tom as he went below.

"I only wish, old fellow, that I could stop on deck and let you send a shot or two into those batteries ahead," he exclaimed, apostrophising his gun.

Jack and Terence felt something like men leading a forlorn hope, but felt that they must of necessity expose themselves to the round shot and bullets of the enemy. They had not long to wait before the guns from the battery opened fire; the first shot struck the starboard bulwarks and went through them, the next plunged right down on the deck, and others followed in quick succession. The enemy now opened with grape and canister, numerous shots pa.s.sing through the sails, and several others striking the deck and bulwarks. Had the crew not gone below many must have been killed or wounded; Jack and Terence, now the only two exposed, were still unhurt, though several missiles whistled close to their ears, and half a dozen lodged in the barricade erected for the protection of s.n.a.t.c.hblock. All Jack's attention was required for conning the brig, so that he could attend to nothing else. After a shot had gone through the deck, he heard cries proceeding up the hatchway as if some one had been hurt below, but he had no time to inquire who was the sufferer. Though from his natural temperament he took a pleasure in being under fire, still he never so heartily wished himself out of it as he did at present. It would have been a different matter had he been able to defend his ship instead of being compelled to glide slowly by and be peppered at without returning a shot. It was, indeed, extremely trying, and it seemed a wonder, considering the number of shots fired down into her, that she was not sent to the bottom. At length the brig had to stand farther out from the cliffs, in a direction where fewer guns could reach her, and Jack determined to try if he could not silence those likely to annoy him with a few rockets and a dose of canister from the carronades. Calling Needham and a dozen of hands on deck, he gave the order. Never did men spring up with greater alacrity. Terence directed the rockets, which pitched right into the fort, while the canister coming directly after, must have driven the Spaniards from their guns, for not a shot was returned till the brig was pretty well out of their reach.

The rest of the crew now came on deck, and gave a loud cheer at the success of their exploit; they had not, however, escaped altogether, one had been killed and two wounded below, a shot entering the gunroom had also killed the clerk in charge, and slightly wounded Jos Green.

Though the brig had pa.s.sed the partly-formed batteries, she was not altogether free from danger. Troops of flying artillery were observed moving along at the top of the cliffs, accompanied by a body of infantry. Though the brig had a strong breeze, as the current was against her, she advanced but at a comparatively slow rate, the troops above getting along almost as fast as she did. A shower of grape from the carronades and a couple of rockets sent into their midst made them, however, sheer off to a respectful distance, and the gallant little _Supplejack_ continued her course without being further molested.

The dead were sewn up in their hammocks with shot at their feet, and lowered into the deep stream, as there was no prospect of being able to bury them on sh.o.r.e. Jos Green made light of his wound, as he did of every other trouble in life, and Jack felt thankful, considering the hot fire to which the brig had been exposed, that more casualties had not occurred.

CHAPTER TWENTY SIX.

THE MIDSHIPMEN SEEN ON THE Sh.o.r.e--A BOAT SENT FROM THE BRIG--THE ENEMY APPEAR ON THE CLIFFS AND OPEN FIRE--THE BRIG RETURNS IT--THE MIDSHIPMEN RESCUED--THE BRIG GETS CLEAR OF THE ENEMY--TOM RECOUNTS HIS AND GERALD'S ADVENTURES.

Evening was approaching, all hands had been busy repairing damages, the carpenters below stopping shot-holes, the rest of the crew on deck knotting and splicing the rigging. Some way ahead was seen a lofty bluff with a range of cliffs, which, the chart showed, extended far along the sh.o.r.e; a shoal ran off it, so the brig had of necessity to steer some distance over to the opposite bank.

As had been done all along, a vigilant lookout was kept for any object moving on the western side. Needham's keen eye was employed in the service; he felt a sincere affection for the youngsters, and longed to recover them almost as much as did their relatives. Just abreast of the brig appeared a shallow valley with a stream in the middle, and trees growing on either side, reaching down to the edge of the water; Needham was examining the spot with even more than his usual care.

"I am sure of it!" he exclaimed suddenly. "One of them is waving his handkerchief, or a bit of rag of some sort. It must be the young gentlemen!"

Jack and Terence brought their gla.s.ses to bear on the spot. The pinnace towing astern was hauled up alongside. Terence and Needham jumped into her with a ready crew. Just as she was shoving off a party of artillery and a body of infantry appeared on the cliffs above.

"Take six small-arm men, in case the enemy should see the lads and attempt to stop them," exclaimed Jack; "the muskets will probably keep the Spaniards at a distance while they get on board."

The men who had been called away having received their ammunition, were in a few seconds in the boat, which now pulled as fast as the crew could bend to their oars towards the sh.o.r.e.

The enemy must have been surprised at seeing her; for not having discovered the midshipmen, they probably did not conceive for what object she was approaching the sh.o.r.e. In the meantime the carronades had been turned towards the cliff, and the rockets got ready. Until fired on, however, Jack had determined not to fire; indeed his shot, at the distance he then was from the cliffs, could not have told with much effect. As it would have been unwise to heave to in so dangerous a position, the topsails were lowered on the caps, and topgallant sails and royals let fly, so as not to leave the boat behind. The midshipmen, for there was no doubt that it was they who were seen, in their eagerness to get on board the boat, came out from beneath the overhanging shrubs which had hitherto concealed them from the view of those on the cliffs, to the end of a point. The enemy caught sight of them, and now understanding the object of the boat, instantly began firing at her, while a party of men hurried down to try and cut them off.

"We must put a stop to that," cried Jack, giving orders to open fire with Long Tom and the carronades. The enemy replied with their field-pieces. The brig, having edged over as close as she could venture, opened on them with rockets.

The boat by this time had scarcely got half way to the sh.o.r.e, while the two midshipmen, seeing the party coming to intercept them, threw themselves into the water and swam off to the boat, regardless of the bullets flying about their heads. They struck out boldly, the boat's crew pulling with all their might to reach them, while the small-arm men kept up a sharp fire on the enemy at the top of the cliffs, which prevented them from taking so accurate an aim as they would otherwise have done.

Jack watched them with the deepest anxiety; he saw the shot splashing into the smooth water and bounding over them. One better aimed might send either of the lads to the bottom. He had not, however, forgotten that he had charge of the brig, and was obliged to turn his eyes away from them to look after her.
