Those who have read the history of Alexander the Great, in this series, will recollect the difficulty he experienced in besieging and subduing Tyre, a great maritime city, situated about two miles from the shore, on the eastern coast of the Mediterranean Sea. Carthage was originally founded by a colony from this city of Tyre, and it soon became a great commercial and maritime power like its mother. The Carthaginians built ships, and with them explored all parts of the Mediterranean Sea. They visited all the nations on these coasts, purchased the commodities they had to sell, carried them to other nations, and sold them at great advances. They soon began to grow rich and powerful.
