The turbulence of the river in spring-time discouraged milling, and, beyond keeping the old red bridge in repair, the busy farmers did not concern themselves with the stream; so the Sandtown boys were left in undisputed possession. In the autumn we hunted quail through the miles of stubble and fodder land along the flat shore, and, after the winter skating season was over and the ice had gone out, the spring freshets and flooded bottoms gave us our great excitement of the year. The channel was never the same for two successive seasons. Every spring the swollen stream undermined a bluff to the east, or bit out a few acres of corn field to the west and whirled the soil away to deposit it in spumy mud banks somewhere else. When the water fell low in midsummer, new sand-bars were thus exposed to dry and whiten in the August sun. Sometimes these were banked so firmly that the fury of the next freshet failed to unseat them; the little willow seedlings emerged triumphantly from the yellow froth, broke into spring leaf, shot up into summer growth, and with their mesh of roots bound together the moist sand beneath them against the batterings of another April. Here and there a cottonwood soon glittered among them, quivering in the low current of air that, even on breathless days when the dust hung like smoke above the wagon road, trembled along the face of the water. It was on such an island, in the third summer of its yellow green, that we built our watch-fire; not in the thicket of dancing willow wands, but on the level terrace of fine sand which had been added that spring; a little new bit of world, beautifully ridged with ripple marks, and strewn with the tiny skeletons of turtles and fish, all as white and dry as if they had been expertly cured. We had been careful not to mar the freshness of the place, although we often swam out to it on summer evenings and lay on the sand to rest. This was our last watch-fire of the year, and there were reasons why I should remember it better than any of the others. Next week the other boys were to file back to their old places in the Sandtown High School, but I was to go up to the Divide to teach my first country school in the Norwegian district. I was already homesick at the thought of quitting the boys with whom I had always played; of leaving the river, and going up into a windy plain that was all windmills and corn fields and big pastures; where there was nothing wilful or unmanageable in the landscape, no new islands, and no chance of unfamiliar birds--such as often followed the watercourses.
