The party started in boats, and ascended the Osage River as far as it was navigable. They then procured horses and travelled to the great Pawnee village known as the Pawnee Republic, which gave its name to the Republican River. Before reaching the Pawnee village they found that a Spanish military expedition, several hundred strong, under an able commander named Malgares, had anticipated them, by travelling through the debatable land, and seeking to impress upon the Indians that the power of the Spanish nation was still supreme. Malgares had travelled from New Mexico across the Arkansas into the Pawnee country; during much of his subsequent route Pike followed the Spaniard's trail. The Pawnees had received from Malgares Spanish flags, as tokens of Spanish sovereignty. Doubtless the ceremony meant little or nothing to them; and Pike had small difficulty in getting the chiefs and warriors of the village to hoist the American flag instead. But they showed a very decided disinclination to let him continue his journey westward. However, he would not be denied. Though with perfect good temper, he gave them to understand that he would use force if they ventured to bar his passage; and they finally let him go by. Later he had a somewhat similar experience with a large Pawnee war party. The Swarms of Game. The explorers had now left behind them the fertile, tree-clad country, and had entered on the great plains, across which they journeyed to the Arkansas, and then up that river. Like Lewis and Clark, Pike found the country literally swarming with game; for all the great plains region, from the Saskatchewan to the Rio Grande, formed at this time one of the finest hunting grounds to be found in the whole world. At one place just on the border of the plains Pike mentions that he saw from a hill buffalo, elk, antelope, deer, and panther, all in sight at the same moment. When he reached the plains proper the three characteristic animals were the elk, antelope, and, above all, the buffalo. The Bison.
