284 EARE 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 Sabella 

 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

I climbed up the sandy cliffs. The great sea-stock 

 (Matthiola sinuata)^ a rare plant, was numerous on 

 these cliffs, now displaying its purple flowers, I was 

 struck with the curious large yellow glands on the 

 leaves and pods. The samphire in dark green tufts,

There was the rest-harrow, the little centaury, both
