St. John's Lodge, near Aylesbury, Jan. 2Mh t 1854. My dear Beaufort, I KNOW not to whom I could in any case have addressed my hydrographical treatise so appropriately as to you, who have so long and ably presided over the surveying department of the navy. But nearly half a century of professional acquaintance, including thirty years of intimate friendship, with the knowledge of you which they have given as a man, a seaman, and an officer, leave me wholly unable to say whether I ought rather to inscribe this work to you as a public compliment, or as a mark of private regard. To you, then, I submit the present exposition of the state of our knowledge of the Mediterranean Sea at the time of my return to England in the close of the year 1824; only regretting, on various counts connected therewith, that you were not holding office at that period. This work, as you are aware, has long been meditated, but has ' hung fire' for the completion of the surveys in the Archipelago, so that it might only just precede a complete Sailing-Directory for the whole Inner Sea. The unexpected breaking off of Captain Graves, however, towards the very close of those operations, and b vi DEDICATION. their consequent suspension, determined me to proceed with my part at once. For this and two or three other reasons, together with the loss occasioned by the destructive conflagration of the printing-office of Messrs. Savill and Edwards, the book is later in its publication than was intended. Still the delay has been of no actual detriment to the Service, since my charts — which, in fact, are working diagrams of all the labour — have long been engraved and circulated by the Admiralty ; while, as you can tes- tify, my observations and memoranda have always been accessible to inquirers. The undertaking, though heavy, is nevertheless not wanting either in interest or importance : the Mediterranean Sea, so secondary in extent compared with others, being, per se, of vast surface, with many of its characteristics on the grandest scale. Besides, viewing it as the actual site where the intellectual culture to which we are most directly indebted was first developed, it cannot but be regarded for its portentous historical occurrences ; nor will a sailor forget that it is the sea whereon the fleets of Carthage, Greece, and Rome contended in former days, and those of Spain, France, Italy, and England in later times. ' The grand object of travelling/ said Dr. Johnson to General Paoli, ' is to see the shores of the Mediter- ranean. On those shores were the four great empires of the world ; the Assyrian, the Persian, the Greek, and the Roman. All our religion, almost all our arts, almost all that sets us above savages, has come to us from the shores of the Mediterranean/ It might appear strange that a coast of such paramount interest should still have required surveying in the present day; but the following pages may, in part, account for the necessity. To what is hereinafter mentioned, it may be prefaced, that useful knowledge has recently spread as largely over the waters as upon land ; much DEDICATION. vii of which must be ascribed to sundry of its older trammels being thrown overboard, and much to the progressive improvement which time naturally and surely creates. Since you and I first dabbled in these matters, a vast stride has been made in hydrography; and the results are seen in more efficient instruments, better astrono- mical tables, sounder nautical directions, and more correct charts. Instead of a Lunarian being a l rara avis' in our ships, as of erst, there is now a very host of them afloat; and chronometers, then so scarce, are at present to be found in every ship of consideration. Meantime, the various branches of available science have been so steadily advancing among seamen of all nations, that besides a higher practice in mechanical navigation, they possess a more accurate information respecting the phenomena of winds and oceanic currents than heretofore. Already the elements are nearly reduced to subjection by the union of science and practical seaman- ship, so that sea-passages are wonderfully shortened within memory ; and these beneficial effects are on the eve of being strengthened in utility by a systematic arrangement and impartial discussion of connected facts, as proposed by the energetic Lieut. Maury, of the United States Navy. In a word, although incompetence may sometimes appear in the van, to the serious detriment of the public interests and character, the true place and substantial advantage of real talent is fast gaining recognition; whence it must follow that inchoate notions, and arbitrary assumptions, will inevitably succumb to experienced skill, and the logical reasonings of induction. It would be deeply important to our knowledge of the terrestrial attributes of our globe, were the profundity, form, and physical nature of the ocean ascertained; but an enormous amount of labour and money must be consumed, before positive conclusions vni DEDICATION. can possibly be arrived at over such an immensity. Indeed, a complete oceanic survey may be beyond human power ; but, to the best of my opinion, a sub-aqueous map of the Mediterranean is within our compass. Towards an object so truly valuable to science, the following pages, it is hoped, may prove a trustworthy pioneer ; albeit my inquiries were mainly directed to our maritime requirements in 1810, the date of my commencing operations in that sea. Still, in conducting examinations and gathering every information in my power, neither toil, responsibility, nor personal expense, were ever spared by Your truly attached friend, CONTENTS. Pakt I.

THE MEDITERRANEAN SEA, PiART I. A CHOROGRAPHICAL VIEW OF THE SHORES OF THE MEDITERRANEAN SEA, WITH ESPECIAL REFER- ENCE TO THEIR PRODUCE AND COMMERCE. § 1. The Mediterranean Shores of Spain. THE Mediterranean Sea, equally remarkable from its position in the midst of the most civilized nations, and its connexion with many memorable events in ancient and modern history, is that vast central gulf emphatically styled in the Sacred Scriptures the Great Sea ; justly receiving that appellation, as being the largest assemblage of waters known to the earliest writers of those records : and indeed its importance was truly paramount among the ancients, as it was the grand key to both portions of the then known world. By the word Mediterranean, or midland, we understand water enclosed either wholly or nearly by land ; but the term was not applied to this sea by any classical writer. The ancient Greeks seem to have had no general name for it, — Herodotus merely calls it ' this sea/ and Strabo the ' sea within the columns/ that is, within Calpe and Abyla. By their present descendants it is called Aspri Thalassa ("Ao-Trp Qakao
