 hilura brown. 



Sloane considers this species to be indigenous to the Island, 

 and says that the seeds were, in his time, used by some as 

 food, and given to fatten hogs. I do not find, however, on 

 inquiry, that any use is at present made of them, except that 

 they are commonly planted, by the Negroes, along the margin 

 of their provision grounds, from a superstitious notion, pro- 

 bably of African origin, very generally entertained, that the 

 Overlook fulfils the part of a watchman, and, from some 

 dreaded power ascribed to it, protects the provisions from 

 plunder. Even the better informed adopt the practice, although 

 they themselves may not place confidence in any particular 

 influence which this humble plant can exercise, either in pre- 

 venting theft, or in punishing it when committed.
