To approach nearer would not have been prudent. The canvas was therefore flattened in, and the brig’s head was once more turned to seaward. Scarcely had she hauled her wind, than the sun having risen high above the land, the mist lifted, and the whole line of coast fringed with mangrove bushes, and here and there with a white belt of sand, appeared in sight. But the chase, where was she? Not a sign of her appeared on the shore, while neither to the north nor to the south was she to be seen. Jack looked at Adair, and Adair looked at Jack, and together they discussed the matter with Alick, but neither of the three could offer any satisfactory explanation of the matter. Captain Grant and the rest of the officers appeared equally puzzled. As the brig stood closer in-shore there was a chance of the mystery being solved. The hands in the chains were kept heaving the lead, which showed that the brig was slowly shoaling her water. At length she was hove-to, and two boats were lowered. Their own lieutenant, Hemming, who had escaped with them from a sinking slaver, volunteered to take charge of one of them, and Evans, the second lieutenant of the brig, went in the other. The former, as the senior officer, had charge of the expedition.

“As she cannot have escaped along shore, and certainly has not evaporated into the air, the chase must have got into some creek or inlet, the mouth of which we cannot distinguish,” observed the captain. “You will therefore search for such an entrance, and pursue, and bring her out if you can.”

“Ay, ay, sir!” answered Hemming, delighted with the work in prospect.

The three midshipmen got leave to go in the boat. Jack accompanied Evans, the other two went with Hemming, as did Jack’s old follower Dick Needham. Away they pulled in high spirits. As they approached the shore they observed that a long line of white surf was breaking heavily on it. Hemming stood up and scanned the coast narrowly, thinking that after all the schooner might have been run on shore, and as slavers are but slightly put together, might have speedily been knocked to pieces. As he stood up, and the boat rose to the top of the swell, he saw not what he expected, but a piece of clear water inside a narrow spit of sand, and a little to the south he observed a spot where the surf broke less heavily, and which he concluded was the entrance to the creek or river.

“I have little doubt that this must be the place where the schooner has taken refuge; and as she has gone up, so may we,” shouted Hemming, pointing it out to his brother officer.

Evans agreed with him, and the two boats pulled away in the direction indicated. That there was an entrance was evident, but it required great caution in approaching it. A capsize would probably prove fatal to all hands—for had any escaped drowning, they would have fallen a prey to the sharks, which in southern latitudes generally maintain a strict blockade at the mouths of rivers, to pick up any offal which the stream may bring down. The boats rose and fell on the smooth swells as they came rolling in. At last Hemming observed a space on the bar clear of broken water. He gave the signal to go ahead.

“Now, my lads, now pull away,” he shouted.

The boats dashed on, the surf roared and foamed on either side of them, and not only did the three midshipmen, but most of the older men in the boats, hold their breath till they were well through it, and once more floating in smooth water inside the bar. Instead of being in a mere creek, they found that they had entered a broad deep river which seemed to come down from a considerable distance in the interior. They pulled on more certain than before of finding the chase. However, after they had gone some distance, they arrived at a spot where the river formed two distinct branches, or, rather, it might be, where another broad stream joined the main current. Up which the schooner had proceeded it was impossible to say.

“I’ll take one stream, you take the other,” shouted Hemming to Evans; and the boats dashed on.

It was important to overtake the schooner before she got higher up, and perhaps hidden away in some narrow creek where it might be no easy matter to find her. The scenery was far from attractive. Little else on either side was to be seen but long lines of mangrove bushes, and as the tide fell black banks of mud began to appear, which it was evident would soon narrow the width of the stream. Evans and Jack took the branch of the stream which came from the southward. It wound about a good deal, so that they were aware they might any moment come on the schooner. They kept their muskets by their sides ready loaded.
