Coming into the latitude of 18° N. we found that part of the sea which is generally so covered with grass that it looks at a distance like a meadow. This grass has a yellowish cast, being hollow within, and on being pressed it yields a clammy viscous juice. In some years none of this grass appears, while in other years it is found in prodigious quantities. Some imagine that it comes from the bottom of the sea, as divers report that the bottom is in many places covered with grass and flowers. Others conceive that it comes from the coast of Africa: But our author disapproves both of these opinions, because, if it came from the bottom, there is no reason why the same appearance should not be found elsewhere; whereas, if it came from the coast of Africa, it ought to be found in other situations, especially near that coast. His opinion, therefore, is, that it comes from the coast of America, and particularly from the Gulf of Bahama, or Mexico, where it is known to grow in great abundance, and where, when it comes to maturity, it breaks off; and is carried away by the currents.2
