Iowa is a prairie state and thus her institutions and students must wrestle with problems growing out of prairie environment. Slightly more than a hundred years ago, about five-sixths of the state consisted of virgin grassland. For thousands of years the prairie vegetation together with air, weather, and water in the course of time, has been making soil; as season after season, organic matter has been deposited among the particles of pulverized rock. Most of the prairie which lived in centuries past, now lies below the surface of the soil; and with the removal of the sod by cultivation, the natural soil building process has ceased;-ceased before man has learned the intricate sequences involved. During more than one hundred years of cultivation, the sod-less prairie-made soil of Iowa has been slipping down the waterways.
