1 From the Arnold Biological Laboratory of Brown University and the Woods Hole Oceanographic Institution
1. Land drainage tends, in general, to raise the buffer capacity-chlorinity ratio of sea water.
2. Heavy rains measurably decrease the proportional effect.
3. The effects of deep soil drainage are greater in raising the ratio than are those of mere surface drainage.
4. The character of the soil alters the effect. Sandy soil may yield measurably less base than a richer soil.
