The larger forms of algae (kelp) are found in the deeper water, while in shallow water and between tide levels are the smaller forms (seaweed). The larger kelps are not numerous as to individual species, but they more than make up for this by forming vast beds, hundreds of square miles in area. Most of the seaweeds are not individually numerous but there are so manj^ species that the rocks, uncovered at low water, can scarcely be seen through the dense growths they Fig. 23.

Photo by Paul Bonnot, May 17, 1929. Very little commercial use has ever been made of this abundance of marine vegetation. California is a comparatively new country and there are many natural resources more easily exploited. During the World War there was flurry of activity in the utilization of the kelps. Products such as potash and iodine which had been previously imported, were not available. Balch (1902) discovered that the kelps were high in potassium salts, so that, with the foreign supply cut off experiments were begun on a large scale to determine the usability of the kelps. While the war lasted several concerns under government subsidy, harvested great quantities of kelp and produced the needed.
