Excerpt from The University of Kansas Science Bulletin, 1915, Vol. 9
In sailing or rowing about the San Juan Archipelago in Puget Sound, one is almost constantly within sight of the kelp beds. The typical plants have a large float, or pneumatocyst, on the surface from which many broad, flat fronds stream outward, in many cases for twelve or fifteen feet. Yet among these plants are many that have lost part or all of their fronds, and the rounded shiny pneumatocyst bulb suggests the term "bald-headed." Since the kelp is recognized as a source of potash for agricultural fertilizers, the loss of a considerable percent of the fronds reduces the weight that might be harvested very seriously, over two-thirds in many cases.
This subject was suggested to the writer by Dr. R. B. Wylie of the University of Iowa, a member of the U. S. kelp investigation staff during the summer of 1913, following a considerable discussion of the kelp, Nereocystis luetkeana, and as full a statement as he was at liberty to give concerning the work being done by that staff. These observations were made in connection with work at the Puget Sound Marine Biological Station, June-August, 1913. It is to be regretted that observations did not begin early in the term, since many plants were without fronds when observations began, while others were still in vigorous growth.
