THE HALE-TIDE POOL. 73 



small twine, and from six to twenty inches long. It 

 adheres well to paper, and may therefore be gathered 

 for the album ; but its chief beauty will only be 

 discovered with a microscope. That common slimy 

 thread, if placed between two slips of glass and 

 pressed, will show an axis composed of closely -packed 

 cells, edged with bead-like filaments, amidst which are 

 innumerable spores. 



There is only one other species — 



Chobdaeia Divaeicata — a native of the Baltic 

 Sea, which we must look for amongst the weed cast 

 up by a storm, and may be known from our British 

 plant by its greater length, paler colour, and dense 

 tufts. 



PADIXA PAVOMA. 



This is an object of much value to collectors. It is 

 a most remarkable plant, so unlike all other seaweed 

 as to be recognized by the simplest description ; and 

 therefore, without a difficult scientific sentence, I 

 advise my readers to look at the bottom of some 

 shallow, sandy, sunny pool about half-tide level, and 

 see if there are not groups of fan-like fronds from 

 two to four inches high — curled inwards, striped 

 across, and glistening in orange, green, grey, or red- 

 dish hues, sprinkled with white chalky powder. The 

 edge of the frond is fringed with delicate hair-like 

 fibres, and curled inwards. 



Fructification. — Very like that of the hart's-tongue
