For two rollicking days they rang endless changes on this fascinating theme. On the third a storm overtook them. Not daring to put into the waters of the Gulf, the Sieur de Iberville decided to risk landing on the rocky coast.

Nobody, then, knew how big the world was. Longitude was not understood. Sailors had to guess at distances east and west. La Salle had thus gone past the Mississippi's mouth whose latitude he knew. The accident had brought his colony to a miserable end at the unfavorable place where they finally landed.

By a lucky chance, since there was no way to reckon the right spot, the Sieur de Iberville went straight into the Great River half hidden behind the outlying palisades. He saved his boats: he found his port. The place of landing he named Mardi Gras for the day, Tuesday, March 3, 1699.

It was a good beginning. After that all the adventurers were eager to go upon exploring parties, to make friends with the Indians, and to build a town. The colonists were ready to set their homes almost any place upon the borders of this summer sea. So the city of the port of the Great River was begun, settled, and stockaded as the Sieur La Salle had prophesied that some day it would be.

It was better not to have all his resources in one place to tempt a buccaneer attack, and so Sieur de Iberville built another fort on Ship Island and one at Biloxi inlet on the north coast.

Ship's Island was an ideal secret refuge, and when it was abandoned by the French colonists for larger quarters on shore it became a rendezvous for pirates of the Gulf. Its silver sand has buried many treasures of gold and gems and it has been dyed with the blood of captured crews. To-day a government station stands upon it and its wicked years are almost forgotten by the honest boats with respectable mariners now sailing tamely past it.

On the bay at Biloxi, the Sieur de Iberville's bastioned fort held a dozen cannon. Later still another fort was built in Mobile Bay. All were intended to guard the coming city at the mouth of the Mississippi and her immense domain. Anthony was one of many to work on these defenses against sea-robbers, or Indians, or rival nations.

One day, while he and the boyish de Bienville and a few armed followers were floating down the Mississippi from one of their numerous scouting trips, what should they see but a full-rigged ship coming to meet them.

Their surprise was mixed with fear. For the ship was English and she carried sixteen guns. And, as they presently learned, a sister ship quite as strong lay off the mouth of the Great River. What if this commander turned those guns on their tiny new town? What if he captured these Frenchmen and took this smaller open boat with its four little cannon?

The stripling de Bienville was a master of men. He promised his crew that they should not be taken. Then he sent a friendly hail to the ruddy captain of the English and beamed confidently at his fellows when it was politely returned. Anthony, who loved courtesy, forgot how scared he was as he listened to the formal speech in which the two leaders conversed.
