all dead reckonin', which is a pretty shaky way of runnin' even a fishin' schooner. Then, again, Harry an' Walter ain't strong enough to handle the wheel in any kind of a decent breeze, an' it's only you an' me. We must lay by till somethin' more'n a good fair chance comes, else we'll find ourselves in a bad scrape."
"Of course you're the one that knows what we ought to do, an' I ain't sayin' a word if we run way down to South America; but it's kinder tough on the boys. I can see 'em, when they think I ain't lookin', wipin' their eyes an' actin' like as if it wouldn't take much to make both yell right out. If they didn't have no more of a home than I've got neither would bother 'bout how long the cruise is likely to last."
"I s'pose it does seem rough," Bob said reflectively; "but what's to be done? I reckon they'd rather loaf 'round here a good many days than take chances on a raft. Sailorizin' is a mighty risky thing for green hands, an' while I can hold my own among the best of 'em in the fo'castle, I'd make a poor fist of navigation. They'll have to grin an' bear it same's many a good man has done before 'em."
Jim had no reply to make. Even before the conversation was begun he realized the difficulty of reaching port unless under the most favorable circumstances; and now since Bob had spoken so freely he resolved to be patient, no matter how long they might remain at sea.
The old sailor, instead of going below, where there would be some trouble to awaken him in the event of a sudden emergency, laid down on the deck to leeward of the house, and a few seconds later his loud breathing told of unconsciousness.
To remain at the wheel, the only one of this small crew awake, and in a certain degree responsible for the safety of all, was a task from which even a more experienced sailor than Jim might be excused for shrinking; but it was a matter which could not well be bettered, and the boy stood up to it bravely. Now and then the white crest of a wave in the distance caused him to start with joy, only to be correspondingly depressed a few seconds later as the true nature of the object was discovered; and thus amid alternate hope and despondency the two long hours of his watch were passed.
Then Bob took his trick at the wheel, Jim camping down on the deck in the place so lately vacated by the old sailor; and when his eyes were closed in slumber he did not open them again until the sun began to send long shafts of golden light across the leaping waters.
"What made you let me sleep so long?" he asked, with just a shade of irritation in his tone. "I was better able to stand watch than you, an' a couple of hours' sleep would a'-fixed me up all right."
"Well, lad, somehow the thinkin' of what might be the end o' this 'ere queer cruise kept me awake, an' when I wasn't sleepy there could be no reason for pullin' you out. We'll square it before dark, though. Now s'posen we get a little grub, call the watch below so's they can take a few lessons in steerin', an' be ready for settin' the canvas."
Jim, feeling that he was in a certain degree responsible for having thus unconsciously shirked his duty, carried out these instructions with the greatest alacrity. When Harry and Walter were awakened they went aft to their teacher in seamanship, while the amateur cook prepared a hearty breakfast, which was served on the top of the house in order that all might eat at the same time.
Then Bob went below for what he called a "double dose of snoozin'." Walter set things to rights in the galley, and Harry steered while Jim stood beside him to make sure the Bonita was kept on the course, exercising as much care as if it was the only one which could be pursued with safety.
Although Bob had fully determined to turn the brig toward the coast on this day, there was no change in her course at noon, and for a very good reason. Before daylight the breeze had died away entirely, and at nine o'clock the Bonita was rising and falling on the glassy ocean with not air enough stirring to lift the narrow thread of blue bunting at the main-truck.
The involuntary crew had spread the yawl's sail from the house to the starboard rail as an awning, for the heat in the cabin was too great to admit of their remaining below, and under this all sought shelter from the sun's fervent rays.
Bob found a reasonably large stock of tobacco among the Bonita's stores, and with this and a short black pipe he occupied himself during the hours of enforced idleness, while the boys thought of home and the loved ones whom they might never see again. The seconds came and went until the sun was directly overhead, and the old sailor had but just settled down for a noonday nap when all four sprang to their feet in alarm, as the deafening crush of an explosion was heard.
The brig quivered from stem to stern as if from the effects of a torpedo beneath her keel, and the fore hatch was flung high in the air while a dense cloud of what appeared to be smoke arose from the hold.
Astonishment and fear rendered the younger members of the crew incapable either of speech or movement, and they might have remained staring stupidly forward an indefinite length of time if Bob had not shouted, excitedly:
"It's a case of fire, lads! Jump to it for what provisions an' water can be got out in a hurry! There's no time to be lost if we want to leave, for most likely the hold is one mass of flame."
These hurriedly-spoken commands aroused the boys from their stupefaction, and in an instant all three leaped toward the pantry. Each took what was nearest at hand, and in a very few moments there was a reasonably large but varied collection of canned provisions in the yawl. No water had been put on board for the very good reason that they could not find a breaker; and Jim shouted, after they had searched several moments in vain:
"We shall have to leave without anything to drink, for we can't get one of the scuttle-butts on the boat."
"I'll stand a pretty good scorchin' afore startin' like that," Bob said decidedly, "'cause you see I know what it is to be thirsty. Fill half a dozen of the fire-buckets while I hunt after bottles."
During all this time the smoke had been pouring from the fore hatchway in dense clouds, apparently giving evidence of some mighty conflagration below; but before a supply of water could be put on the yawl it had fined down to a thin curl of vapor, and to this Jim called Bob's attention just as they were preparing to lower the boat.
"It looks as if somethin' had put the fire out," he said; and Bob replied, as he let go the davit-falls:
"Make fast there, lads, an' I'll take a look below. We don't want to abandon the brig while there's a chance of standin' by her."
The old sailor went forward, the boys remaining aft ready to lower away at a moment's notice, and in a few seconds, to the surprise of all, he was seen going below.
"Now, that's what I call queer!" Jim said after five minutes had passed and Bob did not make his appearance. "He couldn't stay down there very long if the fire amounted to much."
"Perhaps he's been suffocated and can't get back," Harry suggested in a low, tremulous tone.
This idea was sufficient to alarm the other boys, and stopping only long enough to make the falls fast they rushed forward, reaching the fore hatchway just as Bob began to ascend.
"Is the fire very big?" Jim asked; and the reply astonished them quite as much as had the explosion.
"There ain't even a spark!"
"Then what caused the smoke?"
"The brig is loaded with alcohol in casks made of red-oak. That kind of wood is porous, an' the fumes escapin' have formed a gas that looked like smoke, but which had force enough to blow off a hatch that wasn't battened down." Then, as Bob seated himself on the combing and wiped the perspiration from his face, he added: "Now we can have a pretty good idee as to why this craft was abandoned. There was an explosion same as happened a few minutes ago, an' all hands thought what we did – that the brig was on fire. They hove her to an' got the boats over, most likely meanin' to lay at a safe distance until it was possible to find out what would happen. The mainsail was stowed, so she had no after-canvas to hold her steady. Then she got stern-way-on an' backed off till the wind filled her topsails, when she started like a rocket, leavin' the crew behind. Of course she would run a couple of miles, then come to, an' before the men could catch her she'd be off once more. The chances are that them maneuvers were kept up till night set in, when she was lost entirely."
The three boys listened with the utmost attention to this very plausible explanation of what
