limestone at the Priest's Walk, above the town of Swanage. From the 

 blue marl at the marble quarry at Woody Hyde, I have obt'uned two 

 species of fern. 



Minerals. — Carbonate of lime and gypsum are the only minerals worthy 

 of notice. The latter occurs in several states, viz., as needle spar, selenite, 

 satin spar, nodular and in crystals. Carbonate of lime occurs in crystals, 

 but is most remarkable in its fibrous state, which at Ridgeway is called Beef.
