Reconnoitring boats giving such unsatisfactory reports of the depth of the channel, Iberville determined, with his usual energy, to survey it himself. Taking his younger brother Bienville and a crew of his faithful Canadians he started, despite approaching darkness, so as to begin work at day-light; the storm breaking with great violence, Iberville's efforts to make headway over the billows were in vain. Finally, his rowers exhausted, the boat was turned to the nearest land, but the sea was so high and the wind so violent that unceasing efforts were needful to prevent the boat from swamping. It was due to Iberville's great skill that the boat was finally beached in a favorable spot on the sandy beach, which the crew reached with difficulty, so exhausted were they with their struggles. Here they were weather-bound three days, and so had an opportunity to explore the island. It was with horror that they discovered in one place ghastly piles of human bones and skulls, mute witnesses of a scene of slaughter, which terrified many of the crew until they found the island to be uninhabited. The island, now known as Dauphin, was called Massacre by Iberville, who, undisturbed by the sight, visited the mainland with a few of his men and made every effort to discover the inhabitants, of whom he found recent traces. Finally came good weather, and with it the continued voyage to the west brought the fleet to safe anchorage on a bright February morn off Ship Island. The live-stock landed, Iberville gave his freight consorts permission to return to France, while he explored the mainland that now lay fair and bright before him. The Indians were communicated with, after many failures, but, beyond the discovery of the Pascagoula and reports of a larger river to the west, which the Bayagoula Indians called Malbouchia, no valuable information was obtained. Iberville planned to reach the great river by one of its reported outlets, and, following the main channel down, thus learn the way for his vessel; but, the Indians giving him the slip, it only remained to search every foot of the coast until the river was gained. He was thus thrown on his own resources, which had never failed and were not to do so now. Iberville, with his brother Bienville and fifty picked men, largely Canadians, and twenty days' provisions, started February 27th, on two Biscayennes or barges, for his difficult task, the discovery of the mouth of the Mississippi.
