ago, and has been gradually extending its range ever since, until 

 it is now easily first among the marine plants of the district. 



The only part of Prince Edward Island where it has yet been 

 found is the extreme southeast, in the neighborhood of Murray 

 Harbor and Cape Bear. It was first collected there in April, by 

 J. Harper Prowse, but although as abundant as elsewhere, it re- 

 mains so for only a few miles, and then gradually disappears. A 

 solitary drifted specimen, half buried in sand, was found at the 

 Wood Islands, fifteen miles to the west, but it seems not to grow 

 there, and may possibly have drifted from the opposite shores of 

 Nova Scotia. The farmers near Cape Bear gather the seaweeds 

 driven ashore into so-called kelp beds for use as fertilizer. Lam- 

 inaria is however only an occasional constituent, this rockweed 

 forming at least three fourths of the whole. 



On the twelve miles of coast bounding Pictou Island it is no- 

 where wanting. 



-While it has been alleged to grow at two or three points on 

 the Atlantic coast of Nova Scotia, every report definite enough to 

 be investigated has been shown to be without foundation, and at 

 present there is every reason to believe that it is confined to the 

 warmer waters of the Gulf. There its profusion is remarkable 

 in view of its total absence elsewhere. Its only rivals are two 

 other rockweeds, Fuciis vesiculosus and Ascopliyllitm nodosum, 

 and it is not only a more showy plant than either of these, but 

 in the number of individuals exceeds them together.
