Note 8 — Chapter I

The first authentic description of the Mar di Sargasso of Aristotle is due to Columbus. It spreads out between the nineteenth and thirty-fourth degrees of north latitude. Its chief axis lies about seven degrees to the westward of the Island of Corvo. The smaller bank, on the other hand, lies between the Bermudas and Bahamas. The winds and partial currents in different years slightly affect the position and extent of these Atlantic "sea-weed meadows." No other sea in either hemisphere displays a similar extent of surface covered by plants collected in this way. These meadows of the ocean present the wonderful spectacle of a collection of plants covering a space nearly seven times as large as France.—Humboldt's Cosmos.
