284 RARE PLANTS. 



thin horizontal strata, and covered at the top with a 

 layer of poor soil, on which barley was growing. 



At the edge of the rocks, near low water mark, the 

 points and projections of the shale were covered 

 with the curious honey-combed tubes of Sahella 

 alveolata ; a covering which gave to the rocks an 

 appearance of rounded masses, singularly suggestive 

 of the brainstones of tropical seas. Pretty tide-pools 

 and deep inlets occurred between the rocks, with

 these cliffs, now displaying its purple flowers, I was
