Thus it was settled, and as soon as supper was over, after a loving, lingering farewell from his mother, who repeated over and over again her charges that he should shun all perilous adventures, the boy found himself once more afloat. Mrs. Rankin had promised to write a long letter to the Mantons that very evening, assuring them of Worth's safety up to the date of the day before, and being thus relieved from this duty, Sumner set forth, with a light heart on his second cruise up the reef.

The Transit was a comfortable, schooner-rigged sharpie, about sixty feet long, built by the Government for the use of the Coast Survey in shallow southern waters. She had great breadth of beam, and was a stanch sea-boat, though she drew but eighteen inches of water, and Lieutenant Carey had no hesitation in putting her outside for a night run up the Hawk Channel.

The especial duty now to be undertaken was an exploration of the Everglades to ascertain their value as a permanent reservation for the Florida Seminoles. These Indians, hemmed in on all sides by white settlers, were being gradually driven from one field and hunting-ground after another. In consequence they were becoming restive, and the necessity of doing something in the way of assuring them a permanent location had for some time been apparent. Thus a survey of the 'Glades was finally ordered, and Lieutenant Carey had been detailed for the duty, with permission to make up such a party to accompany him as he saw fit.

His present command on the Transit consisted of Ensign Sloe, and six men forward. It was intended that three of these should be taken into the 'Glades, while Mr. Sloe, with the other three, was to take the sharpie, from the point where the exploring party left her, around to Cape Florida, and there await their arrival.

On the deck of the schooner and towing behind her were three novel craft, in which Lieutenant Carey intended to conduct his explorations of the swamps and grassy waterways of the interior. One of these was an open bass-wood canoe built in Canada, shaped very much like a birch bark, and capable of carrying four men. The others were the odd-looking boats, with bottoms shaped like table-spoons, that are so popular as ducking-boats on the New Jersey coast, and are known as Barnegat cruisers. One of these was named Terrapin and the other Gopher, while the open canoe bore the Seminole name of Hul-la-lah (the wind).

Before a brisk southerly breeze, in spite of the boats dragging behind her, the Transit made rapid progress. Ere it was time to turn in, Key West Light was low in the water astern, while that on American Shoal shone steady and bright off the starboard bow. The wind held fresh all night, so that by morning both American Shoal and Sombrero had been passed, and the sharpie was off the western end of Lower Metacumba, with Alligator Light flashing out its last gleam in the light of the rising sun.

Chapter XIV.
WORTH AND QUORUM ARE MISSING.

As Sumner was anxious to reach Lignum Vitæ by the shortest possible route, the Transit was headed in through the channel between Lower Metacumba and Long keys. Both tide and wind being with her, the nimble-footed sharpie seemed to fly past the low reefs and sand-spits on either side. Now she skimmed by the feeding-grounds of flocks of gray pelicans, whose wise expressions and bald heads gave them the appearance of groups of old men, and then passed an old sponge crawl, or the worm-eaten hull of some ancient wreck, both of which were covered with countless numbers of cormorants, gannets, and gulls. Waiting, with outstretched necks and pinions half spread, until the schooner was within a stone's-throw, these would fly with discordant cries of anger, wheel in great circles, and return to the places from which they had been driven the moment the threatened danger had passed.
