Jack actually started, when he first ascertained how distinctly and near the glass he was using brought distant objects. The gulls that sailed across its disk, though a league off, appeared as if near enough to be touched by the hand, and even their feathers gave out not only their hues, but their forms. Thus, too, was it with the surface of the ocean, of which the little waves that agitated the water of the reef, might be seen tossing up and down, at more than twice the range of the Poughkeepsie's heaviest gun. Naked rocks, low and subdued as they were in colour, too, were to be noted, scattered up and down in the panorama. At length Tier fancied his glass covered a field that he recognized. It was distant, but might be seen from his present elevation. A second look satisfied him he was right; and he next clearly traced the last channel in which they had endeavoured to escape from Spike, or that in which the boat had been taken. Following it along, by slowly moving the glass, he actually hit the rock on which Mulford had been deserted. It was peculiar in shape, size, and elevation above the water, and connected with the circumstance of the channel, which was easily enough seen by the colour of the water, and more easily from his height than if he had been in it, he could not be mistaken. The little fellow's heart beat quick as he made the glass move slowly over its surface, anxiously searching for the form of the mate. It was not to be seen. A second, and a more careful sweep of the glass, made it certain that the rock was deserted.

Although a little reflection might have satisfied any one Mulford was not to be sought in that particular spot, so long after he had been left there, Jack Tier felt grievously disappointed when he was first made certain of the accuracy of his observations. A minute later he began to reason on the matter, and he felt more encouraged. The rock on which the mate had been abandoned was smooth, and could not hold any fresh water that might have been left by the late showers. Jack also remembered that it had neither sea-weed nor shell-fish. In short, the utmost malice of Spike could not have selected, for the immolation of his victim, a more suitable place. Now Tier had heard Harry's explanation to Rose, touching the manner in which he had waded and swum about the reef that very morning, and it at once occurred to him that the young man had too much energy and spirit to remain helpless and inactive to perish on a naked rock, when there might be a possibility of at least prolonging existence, if not of saving it. This induced the steward to turn the glass slowly over the water, and along all the ranges of visible rock that he could find in that vicinity. For a long time the search was useless, the distance rendering such an examination not only difficult but painful. At length Jack, about to give up the matter in despair, took one sweep with the glass nearer to the brig, as much to obtain a general idea of the boat-channels of the reef, as in any hope of finding Mulford, when an object moving in the water came within the field of the glass. He saw it but for an instant, as the glass swept slowly past, but it struck him it was something that had life, and was in motion. Carefully going over the same ground again, after a long search, he again found what he so anxiously sought. A good look satisfied him that he was right. It was certainly a man wading along the shallow water of the reef, immersed to his waist—and it must be Mulford.

So excited was Jack Tier by this discovery that he trembled like a leaf. A minute or two elapsed before he could again use the glass; and when he did, a long and anxious search was necessary before so small an object could be once more found. Find it he did, however, and then he got its range by the vessel, in a way to make sure of it. Yes, it was a man, and it was Mulford.

Circumstances conspired to aid Jack in the investigation that succeeded. The sun was near setting, but a stream of golden light gleamed over the waters, particularly illuminating the portion which came within the field of the glass. It appeared then that Harry, in his efforts to escape from the rock, and to get nearer to the edge of the main channel, where his chances of being seen and rescued would be ten-fold what they were on his rock, had moved south, by following the naked reef and the shallow places, and was actually more than a league nearer to the brig than he would have been had he remained stationary. There had been hours in which to make this change, and the young man had probably improved them to the utmost.

Jack watched the form that was wading slowly along with an interest he had never before felt in the movements of any human being. Whether Mulford saw the brig or not, it was difficult to say. She was quite two leagues from him, and, now that her sails were furled, she offered but little for the eye to rest on at that distance. At first, Jack thought the young man was actually endeavouring to get nearer to her, though it must have been a forlorn hope that should again place him in the hands of Spike. It was, however, a more probable conjecture that the young man was endeavouring to reach the margin of the passage, where a good deal of rock was above water, and near to which he had already managed to reach. At one time Jack saw that the mate was obliged to swim, and he actually lost sight of him for a time. His form, however, reappeared, and then it slowly emerged from the water, and stood erect on a bare rock of some extent. Jack breathed freer at this; for Mulford was now on the very margin of the channel, and might be easily reached by the boat, should he prevail on Josh, or Simon, to attempt the rescue.

At first, Jack Tier fancied that Mulford had knelt to return thanks on his arrival at a place of comparative safety; but a second look satisfied him that Harry was drinking from one of the little pools of fresh water left by the late shower. When he rose from drinking, the young man walked about the place, occasionally stooping, signs that he was picking up shell-fish for his supper. Suddenly, Mulford darted forward, and passed beyond the field of the glass. When Jack found him again, he was in the act of turning a small turtle, using his knife on the animal immediately after. Had Jack been in danger of starvation himself, and found a source of food as ample and as grateful as this, he could scarcely have been more delighted. The light now began to wane perceptibly, still Harry's movements could be discerned. The turtle was killed and dressed, sufficiently at least for the mate's purposes, and the latter was seen collecting sea-weed, and bits of plank, boards, and sticks of wood, of which more or less, in drifting past, had lodged upon the rocks. “Is it possible,” thought Jack, “that he is so werry partic'lar he can't eat his turtle raw! Will he, indeed, venture to light a fire, or has he the means?” Mulford was so particular, however, he did venture to light a fire, and he had the means. This may be said to be the age of matches—not in a connubial, though in an inflammatory sense—and the mate had a small stock in a tight box that he habitually carried on his person. Tier saw him at work over a little pile he had made for a long time, the beams of day departing now so fast as to make him fearful he should soon lose his object in the increasing obscurity of twilight. Suddenly a light gleamed, and the pile sent forth a clear flame. Mulford went to and fro, collecting materials to feed his fire, and was soon busied in cooking his turtle. All this Tier saw and understood, the light of the flames coming in proper time to supply the vacuum left by the departure of that of day.

In a minute Tier had no difficulty in seeing the fire that Mulford had lighted on his low and insulated domains with the naked eye. It gleamed brightly in that solitary place; and the steward was much afraid it would be seen by some one on deck, get to be reported to Spike, and lead to Harry's destruction after all. The mate appeared to be insensible to his danger, however, occasionally casting piles of dry sea-weed on his fire, in a way to cause the flames to flash up, as if kindled anew by gunpowder. It now occurred to Tier that the young man had a double object in lighting this fire, which would answer not only the purposes of his cookery, but as a signal of distress to anything passing near. The sloop-of-war, though more distant than the brig, was in his neighbourhood; and she might possibly yet send relief. Such was the state of things when Jack was startled by a sudden hail from below. It was Spike's voice, and came up to him short and quick.

“Fore-topmast cross-trees, there! What are ye about all this time, Master Jack Tier, in them fore-topmast cross-trees, I say?” demanded Spike.

“Keeping a look-out for boats from the sloop-of-war, as you bade me, sir,” answered Jack, coolly.

“D'ye see any, my man? Is the water clear ahead of us, or not?”
