mystic properties. With these round stones the point of a needle was rubbed, as often as it required fresh magnetising.
I have already described the compass used by the Phoenicians, and how, long after Islamism had gained the ascendency, it was possessed by their descendants. At length the secret was divulged, and it came into general use among the mariners of the Mediterranean in the tenth and eleventh centuries. Its original form was unaltered for nearly four centuries, when, in 1502, Flavio Gioja of Positano, near the town of Amalfi, on the coast of Calabria, a place celebrated for its maritime enterprise, improved upon the primitive rude and simple instrument by suspending the needle on a centre, and enclosing it in a box. The advantages of his invention were so great that his instrument was universally adopted, and hence he gained the credit of being the inventor of the mariner's compass, of which he was only the improver.
Long before the compass was used at sea, it had been employed by the Chinese to direct the course of their caravans across the desert. For this purpose a figure, placed in a waggon which led the caravan, was so constructed that the arm and hand moved with perfect freedom, the magnetic needle being attached to it; the hand, however, pointed to the south, the negative end being fixed in it. The Chinese also used a needle which was freely suspended in the air, attached to a silken thread, and by this means they were able to determine the amount of the western variation of the needle. It is possible that both the Chinese and Arabs discovered the magnetic powers of the loadstone, although the latter in their long voyages may have allowed the knowledge they possessed to have been drawn from them by the astute Chinese; or, vice versa, the Arabs may have obtained the knowledge which the Chinese already possessed, and kept it secret from the western nations. We all remember the wonderful adventures of Sinbad the Sailor, as narrated in the Arabian Nights--how the ship in which he sailed was attracted by a magnetic mountain, which finally drew all the iron bolts and nails out of her. Now it happens that the author places Sinbad's mountain in the same part of the world in which the Chinese say their magnetic mountain exists. Ptolemy, in his geography, also describes a magnetic mountain existing in the Chinese Seas. We may therefore, I think, come to the conclusion, that the mariner's compass was known to the ancients long before the Christian era, and that although disused for centuries, the knowledge was never altogether lost.
CHAPTER TWO.
EARLY ENGLISH SHIPS (FROM A.D. 600 TO A.D. 1087.)
We Englishmen undoubtedly derive a large portion of our nautical spirit from our Saxon ancestors, the first bands of whom came to the shores of our tight little island under those sea-rovers known as Hengist and Horsa, invited by the helpless Britons to defend them from the attacks of the savage Picts and Scots. The enemies of the gallant heroes I have named were apt to call them pirates; but as might made right in most sublunary affairs during those dark and troubled ages of the world's history, they looked upon the roving commissions they had given themselves as perfectly honourable and lawful, and felt no small amount of contempt for the rest of mankind who chose to stay at home at ease by their firesides, while they were ploughing the ocean in search of plunder and glory. I suspect that they had a strong preference for the former.
After the Saxons had driven the ancient inhabitants of the island out of the more fertile portions of the country, and had made themselves, according to their notions, pretty comfortable in their new homes; they, in a little time, in their turn, were sadly pestered by foreign invaders. These were the Danes. Those hardy sons of the North, still more wild and fierce than the Saxons, and still less scrupulous in their proceedings, pleased with the appearance of the country which they had come over to look at, settled themselves in every nook and corner of Old England in which they could haul up their ships, and find a resting place for their feet. I cannot help feeling a great respect for those old sea-kings. They were heathens, and we must judge of them by the light which they possessed, and not by any standard acknowledged in the present civilised world. Bold, enterprising, and sagacious, their own country confined and barren, they looked on the wide ocean as the only worthy field for the employment of their energies. They loved it for itself, too; they were born on it, or within the sound of its surges; they lived on it, they fought on it,
