The little yacht "Restless," of which we have spoken, on one of her exploring tours, visited Delaware Bay, and ascended that beautiful sheet of water as far as the Schuylkill River. Runners were also sent back from the forts, to follow the narrow trails far into the woods, to open communication with new tribes, to examine the country, and to obtain a more intimate acquaintance with the manners and customs of the Indians. In the spring of 1617 a very high freshet, accompanied by the breaking up of the ice, so injured Fort Nassau that the traders were compelled to abandon it. A new and very advantageous situation was selected, at the mouth of the Tawasentha Creek, subsequently called Norman's Kill. This name is said to have been derived from a native of Denmark, called the Norman, who settled there in 1630. In this vicinity there was a very celebrated confederation of Indian tribes called the Five Nations. These tribes were the Mohawks, Oneidas, Onondagas, Cayugas and Senecas. They were frequently known by the generic name of the Iroquois. When the Dutch arrived, the Iroquois were at war with the Canadian Indians, who, though composed of different tribes, were known by the general name of the Algonquins. The Iroquois had been worsted in several conflicts. This led them eagerly to seek alliance with the white men, who, with their wonderful instruments of war, seemed to wield the energies of thunder and lightning. The Algonquins had, some years before, formed an alliance with the French in Canada. The Iroquois now entered into an alliance with the Dutch. It was a very important movement, and the treaty look place, with many surroundings of barbaric pomp, on the banks of the Norman's Kill. Ambassadors from each of the five tribes graced the occasion. Leading chiefs of several other tribes were also invited to be present, to witness the imposing ceremony. The garrison furnished for the pageant the waving of silken banners and the exhilarating music of its band. The Indian chiefs attended with their decorated weapons, and they were arrayed in the richest costume of war paint, fringed garments, and nodding plumes. The assembly was large. The belt of peace, gorgeously embroidered with many-colored beads, on softly-tanned deer skin, was held at one end by the Iroquois chieftains, and at the other by the prominent men of the Dutch Company, in their most showy attire. The pipe of peace was smoked with solemn gravity. The tomahawk was buried, and each party pledged itself to eternal friendship. The united nation of the Iroquois, in numbers and valor, had become quite supreme throughout all this region. All the adjacent tribes bowed before their supremacy. In Mr. Street's metrical romance, entitled "Frontenac" he speaks, in pleasing verse, of the prowess and achievements of these formidable warriors.
