The material is used as food by the microorganisms, and, as a consequence, they mul- tiply rapidly within the decaying substances, developing vigorously for a time. After they have used up the food, their growth is checked and some of them remain ready to grow again when more organic matter comes within their reach. By their action, then, every bit of organic matter which reaches the soil is seized and rapidly decomposed. The chemical nature of these destructive changes is very compKcated and highly varied. It will be a long time before our chemists understand them, for they involve problems in phvsioloer- ical and organic channstry ye. unsolvrf. We know 4a[ many new products are formed, and that these new products must be regarded as belonging to at least two types, so far as concerns their.
