another motive with the person under whose superintendence the bread was prepared. During the voyage from Methone, where fresh bread was taken on board to the southern coast of Sicily, from which, according to modern language, they were to take their departure for Africa, they were becalmed, and 161 days were spent in this navigation. An incident is mentioned relating to this part of the voyage, which points out the method used by the ancients to preserve their water when at sea. As the general himself was exposed to the intolerable hardship of thirst, or the necessity of drinking bad water, that which was meant for his use was put into glass bottles, which were buried deep in the sand, in a part of the ship to which the rays of the sun could not reach. Three months after the departure of the fleet from Constantinople, the troops were landed near Carthage; Belisarius being anxious to effect this as soon as possible, as his men did not hesitate to express their belief, that they were not able to contend at once with the winds, the waves, and the barbarians. The result of this expedition was the conquest of the African provinces, Sardinia, and Corsica. The absurd and injudicious regulations of Justinian, respecting the corn trade of the empire have been already noticed; nor did his other measures indicate, either a better acquaintance with the principles of commerce, or more regard to its interests. The masters of vessels who traded to Constantinople were often obliged to carry cargoes for him to Africa or Italy, without any remuneration; or, if they escaped this hardship, enormous duties were levied on the merchandize they imported. A monopoly in the sale of silk was granted to the imperial treasurer; and, indeed, no species of trade seems to have been open and free, except that in cloth. His addition of one-seventh to the ordinary price of copper, so that his money-changers gave only 180 ounces of that metal, instead of 210, for one-sixth of an ounce of gold, seems rather to have been the result of ignorance than of fraud and avarice; since he did not alter the gold coin, in which alone all public and private payments were made. At this time, the geographical knowledge of the Romans, respecting what had formerly constituted a portion of their empire, must have declined in a striking manner, if we may judge from the absurd and fabulous account which Procopius gives of Britain. And the commercial relations of the Britons themselves had entirely disappeared, even with their nearest neighbours; since, in the history of Gregory of Tours, there is not a single allusion to any trade between Britain and France. At the beginning of the seventh century we glean our last notice of any event connected with the commerce and maritime enterprise of the Romans; and the same period introduces us to the rising power and commerce of the Arabians.
