The two chief topics of thought and conversation, the two subjects which beyond all others engrossed and absorbed the minds of the settlers, were the land and the Indians. We have already seen how on one occasion Clark could raise no men for an expedition against the Indians until he closed the land offices round which the settlers were thronging. Every hunter kept a sharp lookout for some fertile bottom on which to build a cabin. The volunteers who rode against the Indian towns also spied out the land and chose the best spots whereon to build their blockhouses and palisaded villages as soon as a truce might be made, or the foe driven for the moment farther from the border. Sometimes settlers squatted on land already held but not occupied under a good title; sometimes a man who claimed the land under a defective title, or under pretence of original occupation, attempted to oust or to blackmail him who had cleared and tilled the soil in good faith; and these were both fruitful causes not only of lawsuits but of bloody affrays. Among themselves, the settlers' talk ran ever on land titles and land litigation, and schemes for securing vast tracts of rich and well watered country. These were the subjects with which they filled their letters to one another and to their friends at home, and the subjects upon which these same friends chiefly dwelt when they sent letters in return.
