Near the outlet of Lake Harney was located the residence of King Philip, a Seminole cazique, on a shell plateau in rear of which is a burial-mount, twelve feet high, surrounded by a trench. The following graphic description, taken from Professor Wyman, will enable us to form an idea of its extent:

“This shell-mound is about four hundred and fifty feet in length, with an average of one hundred and twenty in breadth. It stretches nearly at right angles to the river, borders a lagoon on the south, and on the north merges into cultivated fields, over which its materials have become somewhat scattered—its greatest height being about eight feet. Fragments of pottery may be found anywhere on the surface, and with these the bones of various edible animals. Excavations were made at many points, from a few inches to several feet in depth, to ascertain if similar objects were within its interior. The most unequivocal evidence that this mound, while in process of erection, had been occupied by the aborigines was obtained from a pit four or five feet in diameter, and from five to six feet deep, which was dug near the center. Not only were fragments of pots and bones found at all depths, but at the distance of three feet the remains of an old fire-place were uncovered, consisting of a horizontal layer of charcoal, beneath which were perfectly calcined shells, and near these others more or less blackened with heat. Still farther off were fragments of the bones of deer, birds, turtle, and fish—all just as they would naturally have been left around a fire where cooking had been done for some time. In addition it may be mentioned, as a matter of negative evidence, that not a single article was discovered which could have been attributed to the white man.”

Near the outlet of Lake Jessup are the remains of a mound nine hundred feet in length, with an average width of one hundred to one hundred and fifty feet. This structure has been much wasted by the river, but originally it must have been among the largest in the State. That the Indians confined their encampments, or at all events their cooking, almost entirely to these mounds, is proved by the fact that fragments of pots were found in large quantities along the shore wherever the shells are seen in the bank, and not elsewhere, though careful search was made for them. Fragments of deer-bones, turtle, and alligator, were also seen. The shells forming these mounds were chiefly paludinas, or fresh-water snails, although unios and apellarias are met with also.

Mounds on the sea-shore are composed entirely of marine shells, also containing clay-ware, ashes, and charcoal. On the St. John’s, at different times, and by various naturalists, over fifty mounds have been explored, in some of which were seen human bones having the appearance of violence. As so few remains were found during these excavations that had the appearance of being subjects of regular interment, the question is suggested, What disposition was made of their dead, unless all the numerous vessels seen, which could not have subserved for cooking, contained the ashes of their friends which had been cremated?

Mounds have been opened in various portions of the State abounding in fluviatic muscles and clams, the inference being that they contained pearls, and for that reason had been opened. These mounds can be accounted for in two ways—the first and most important: they consumed the contents of these shells, of which they were very fond; the last was the necessity for elevated plateaus to protect them from the sudden inundation of streams when they were traveling through the country camping, consequently they utilized the débris as a prevention against accidents. In their journeyings they depended entirely upon the products of the forest and streams for sustenance, and for this reason followed the water-courses, stopping, like the migratory birds, wherever night overtook them.

Many copper weapons of warfare have been discovered in these earth-works, the metal of which was brought from the mines of Lake Superior, when the Indians followed the great river to the sea, three thousand years ago. These faint traces of mechanical and architectural skill favor the idea of a more enlightened race than that which possessed the soil when first discovered by the Spaniards—a society which, no doubt, sank amid storms, overthrown and shattered by unavoidable catastrophes. In Florida no discoveries have been made which evidence marks of a great nation, while in Mexico and on the Pacific coast, south, they increase.

The Creeks, Cherokees, and Seminoles all agree in attributing the mounds of Florida to a race anterior to their own, as their traditions are handed down “that they were here when their ancestors took possession of the country.” It is also asserted that the Florida Indians formerly worshiped the sun, which fact has been ascertained by their heraldic devices; also the location of their temples in such a manner that the first morning ray from this rising luminary would flash upon their sacred edifice—the Medicine Man, or High-priest, being in attendance to present his invocations with symbolic gestures, whose mysteries were a sealed book to all those around him, but supposed to be well understood by the Great Spirit, whose favor they wished to obtain. The Everglade Indians now venerate the moon, which can be seen from the silver crescent ornamental emblems with which they deck their persons. Like the ancient Greeks, they deposited the remains of their dead in burial urns, the difference being that the Greeks always prepared the bodies by cineration, when the ashes only were entombed, while the entire bodies of Indian children have been discovered in clay vases in the Florida tumuli. In sepulchral mounds about Tampa were discovered large quantities of the heaven-born product called pearls, which created much interest and more cupidity among the Spanish settlers than we could well imagine. It is Pliny who tells us that dew-drops distilled from the heavens, or falling into the mouths of oysters, in certain localities, were converted into pearls. The Florida coast was looked upon by the adventurers who first landed here as the long-sought-for country which contained these treasures. After the arrival of De Soto on the coast of Espiritu Santo they were welcomed by the Empress, who presented them with pearls as the most costly offering from her domains, for which kindness these cruel creatures dragged her about as a hostage for their own security. However, when an opportune moment presented itself, she succeeded in making her escape, at the same time recovering large quantities of imperforate pearls which the Indians through fear had permitted them to rob from their dead. However much evanescent satisfaction these newly-found treasures supplied them with, history makes no mention of Spanish officials being enriched by the discovery. The enormous size which the fertile imagination of those explorers mention them does not come within the present limits of these precious gems of commerce.

The Indians understood the method of making beads from the conch-shells, their novelty and delicate color attracting the Spaniards—the size being equal to an acorn, and larger. The natives persisted in boring the pearls with a heated copper spindle, that they might be worn as ornaments for the neck, arms, and ankles, which rendered them valueless for other purposes.

Pearls are frequently found now on the south coast of Florida the size of an English pea, and less. Some of these are taken from clam-shells of immense size, weighing two or three pounds; also found in the oyster. These are all opaque, some of them slightly pink, a dull white, or the usual pearl color. Those examined by connoisseurs have never been considered of any positive value in the manufacture of jewelry. Both from study and observation we are led to the conclusion that, whatever might have been the impression received by the overwrought imaginations of the Castilian explorers, no pearls of great price, fed by heavenly dews, have ever existed or been discovered on the Florida coast.

Let us now pause and inquire, Who were the architects of these earth-works? What was their fate? and whither did they flee when overpowered? We have only proof that a nation has perished, leaving no record or history but these monuments. They must have had some knowledge of engineering, or they never could have reared such enduring, well-proportioned structures. While the subject furnishes food for reflection, the dark curtain drawn over their obscure presence has never been raised; however great the effort made by those who have desired to penetrate their unyielding secrets, the key to open these hidden mysteries has never been found. Whether called tumuli, plateaus, or mounds, they are objects of interest, in whatever locality they may be seen, of sufficient importance to engage the attention of the scientist when generations yet unborn shall walk the earth, and vainly try to pierce the portals of the silent past.
