Despairing of finding his long-sought El Dorado in that direction, Soto marched south and then southwest, in all a hundred and ten leagues, to Quiguate, a town on a branch of the Mississippi. It was the largest they had yet seen. The Indians abandoned it; but one half the houses were sufficient to shelter the whole of Soto’s force. On the first of September the expedition reached Coligua,—a populous town in a valley among the mountains, near which vast herds of bison roamed. Then crossing the river again,[848] Soto’s jaded and decreasing force marched onward. Cayas, with its salt river and fertile maize-lands, was reached; and then the Spaniards came to Tulla, where the Indians attacked them, fighting from their housetops to the last. The cacique at last yielded, and came weeping with great sobs to make his submission. Marching southeast, Soto reached Quipana; and crossing the mountains eastward, wintered in the province of Viranque, or Autiamque, or Utianque, on a branch of the Mississippi, apparently the Washita.[849] The sufferings of the Spaniards during a long and severe winter were terrible, and Ortiz, their interpreter, succumbed to his hardships and died. Even the proud spirit of Soto yielded to his disappointments and toil. Two hundred and fifty of his splendid force had left their bones to whiten along the path which he had followed. He determined at last to push to the shores of the Gulf, and there build two brigantines, in order to send to Cuba and to New Spain for aid. [Illustration: SOTO.

Here he fell ill of the fever; difficulties beset him on every side, and he sank under the strain. Appointing Luis de Moscoço as his successor in command, he died on the 21st of May. The _Adelantado_ of Cuba and Florida, who had hoped to gather the wealth of nations, left as his property five Indian slaves, three horses, and a herd of swine. His body, kept for some days in a house, was interred in the town; but as fears were entertained that the Indians might dig up the corpse, it was taken, wrapped in blankets loaded with sand, and sunk in the Mississippi.[850] [Illustration: AUTOGRAPH OF SOTO.] Muscoço’s first plan was to march westward to Mexico. But after advancing to the province of Xacatin, the survivors of the expedition lost all hope; and returning to the Mississippi, wintered on its banks. There building two large boats, they embarked in them and in canoes. Hostile Indians pursued them, and twelve men were drowned, their canoes being run down by the enemy’s _periaguas_. The survivors reached the Gulf and coasted along to Pánuco.[851]
