 hack of the lighthouse is covered with plants of Fragaria chiloensis, a large proportion of which 

 are attacked by the stem nematode, Tylench us dipsaci. B, Bluff at Seal Rocks, south of New- 

 port, Oreg. On top of this bluff are beds of the wild sand strawberry severely attacked by 

 Tylenchus dipsaci. C, A small bed of wild strawberries on the gradually sliding slope of the
