One autumn afternoon in southeastern Missouri, seated upon some driftwood on the shallow margin of the Mississippi, I discovered a primitive craft that was carrying a colony of adventurous tree seeds down the mighty river. As I watched and listened, the nuts pattered upon the fallen leaves and the Father of Waters purled and whispered as he slipped his broad yellow-gray current almost silently to the sea. Here and there a few broad-backed sandbars showed themselves above the surface, as though preparing to rise up and inquire what had become of the water. This primitive craft was a log that drifted low and heavy, end on with the current. It was going somewhere with a small cargo of tree seeds. Upon a broken upraised limb of the log sat a kingfisher. As it drifted with the current, breezes upon the wooded hill-tops decorated the autumn air with deliberately falling leaves and floating winged seeds. The floating log pointed straight for a sand-bar upon which other logs and snags were stranded. I determined, when it should come aground, to see the character of the cargo that it carried. Now and then, as I sat there, the heavy round nuts like merry boys came bounding and rattling down the hillside, which rose from the water's edge. Occasionally as a nut dropped from the tree-top he struck a limb spring board and from this made a long leap outward for a roll down the hillside. These nuts were walnut and hickory; and like most heavy nuts they traveled by rolling, floating, and squirrel carriage. One nut dropped upon a low limb, glanced far outward, and landed upon a log, from which it bounced outward and went bouncing down the hillside _aplunk_ into the river. Slowly it rolled this way and that in the almost currentless water. At last it made up its mind, and, with the almost invisible swells, commenced to float slowly toward the floating log out in the river. By and by the current caught it, carried it toward and round the sand-bar, to float away with the onsweep toward the sea. This nut may have been carried a few miles or a few hundred before it went ashore on the bank of the river or landed upon some romantic island to sprout and grow. Seeds often are carried by rivers and then successfully planted, after many stops and advances, far from the parent tree.
