shore. Miss Booth found it floating up from deep 

 water at Orient, L. I. Mrs. Davis collects it in 

 tide pools at Gloucester. It is not a rare plant, 

 though not very common. It may be found from 

 July to October, and very likely later. I have some 

 very fine plants collected by Mr. Young, at Hell 

 Gate, New York city, the last part of September. 

 It may no doubt be looked for in the same situa- 

 tions on the Pacific coast, as it grows nearly all 

 over the globe. I have a fine specimen from Dr. 

 Dimmick, of Santa Barbara, California. It is of 

 a dark green color, and its delicate feathery frond 

 can never be mistaken, when seen displayed in all 

 its rare beauty in the crystal waters of the rocky 

 basins where it makes its home. When mounted 

 and dry it adheres well to paper and has a peculiar 

 glossy look.
