312 Puget Sound Marine Sta. Pub. Vol, 1, No. 27 



Ten kelps were pulled up to examine their anchorage. One was at- 

 tached to a single large stone (8 or 10 inches in diameter). Each of the 

 others was attached to several small stones (1 to 4 inches in diameter). 



8. March 25, 1916. Low tide (-|-1.4 ft.). Observations made from 

 shore only. Could find no kelp at all either young or old. 



9. April 22, 1916. Low tide (+0.3). Found only one old (1915 

 crop) kelp plant. Its fronds were all gone and, while it was still at- 

 tached, its holdfast loosened by very slight pulling. Two young kelps 

 were growing on the lower part of its stipe. One of these was 12 inches 

 long and the other 7 inches. These were the only young plants found 

 that could be positively identified as Nereocystis, although there were 

 many young Laminariaceae less than three inches long growing on the 

 rocks on shore near low tide. Some of these may have been Nereocystis 

 but the close similarity among the several genera of this family during tl">. 

 early stages made it impossible to identify any of them positively. 



10. May 20, 1916. Low tide ( — 0.8). Water very rough. Kelps 

 were abundant both on shore and in the water. Measured 37 kelps. The 

 longest was 11 feet and the shortest was 7 inches. The average length 

 was 43 inches. A careful search was made for fruiting specimens but 

 only three were found. The average length of the three was 10 feet. Two 

 of them had already lost several soral patches near the ends of the fronds. 

 There were numerous specimens of Laminariaceae growing above low 

 tide whose genus it would be impossible to identify positively. Kelps 

 were numerous at 1 foot (vertical distance) above low tide and a num- 

 ber were found even 3 feet above low tide. Effects of desiccation were 

 plainly seen on some of these. 



11. June 20, 1916. Low tide ( + 1.9 ft.) was at 3:05. We arrived 

 at 3 :50. Plenty of kelps were seen where the water was 2 feet or more 

 deep but none could be found on shore or in the very shallow water. Seven 

 kelps were measured. Their average length was 15 feet. The shortest 

 was 13 feet and the longest 16 feet. All of these specimens but one were 

 fruiting. 



12. July 14, 1916. Low tide ( — 0.09 ft.). Found 11 kelps exposed at 

 this stage of the tide. The shore along the whole edge of the bed was 

 examined but no more could be found. The eleven specimens averaged 4 

 feet in length. The shortest was II/2 feet, and the longest 9lA feet. None 

 of them was fruiting. But few fronds were present on any of them and 

 the few that were present were badly beaten to pieces. All of these 1 1 

 kelps were attached to small stones. 



The bed was over 700 feet long. Its width was from 20 to 65 feet. 

 Three spiral kelps of the usual type were found.
