The following description of Silver Spring, written by Prof. John Le Conte, although entirely divested of myth and mystery, contains truthful facts that continue to invest it with a charm which stirs the current of our thoughts as no other natural scenery in the State: "This remarkable spring is situated near the center of Marion county, in the State of Florida, in latitude 29° 15´ north, and longitude 82° 20´ west. It is about five miles north-east of Ocala, the county-seat, and nearly in the axis of the peninsula, being equally distant from the Atlantic and Gulf coasts. Its waters are discharged by a short stream bearing the same name, which, after running about six miles, unites with the Ocklawaha, a tributary of the St. John's River. The stream takes its origin in a deep pool, or head-basin, which is called the Silver Spring. This basin is nearly circular in shape, about two hundred feet in diameter, and surrounded by hills covered with live-oaks, magnolias, sweet-bays, and other gigantic evergreens. The amount of water discharged is so large that small steamers and barges readily navigate the Silver Spring, up to the pool, or head-spring, where there is a landing for the shipment of cotton, sugar, and other produce. These steamers and barges make regular trips between the Spring and Pilatka, on the St. John's. The boatmen informed me that at its junction with the Ocklawaha more than one-half the water is contributed by the Silver Spring stream. This stream, for about two miles from its source, varies in breadth from forty-five to one hundred feet, and its depth in the shallowest parts from ten to fifteen feet, its average velocity being about two miles per hour. The fluctuations of water-level in this spring seem to be connected with the season of rains, but never varying more than two feet. The commencement of the rainy season changes from the 15th of June to the 15th of July. The waters of the spring begin to rise about the middle of the season of summer rains, and attain their maximum height about its termination. The maximum depth of water in the basin constituting the head of the spring was found to be not more than thirty-six feet in the deepest crevice from which the water boils up; the general depth in the central and deep parts of the basin was found to be about thirty feet. Inasmuch as accurate quantitative determinations, however easily applied, are seldom resorted to by the unscientific, we need not be surprised that its real depth falls very far short of its reputed depth. In South Carolina, the reported depth was variously stated at from one hundred and twenty to one hundred and fifty feet, while the smallest estimate in the vicinity of the spring was forty-five feet! This affords an illustration of the general law, that the accuracy of popular statements bears an inverse proportion to the distance from the point of observation--probably, like all emanations from centers, following the law of inverse squares.
