 is furnished by the pulp , which is a charac-

 in the beginning of December. On the wild 

 Olive five or six drupes are ripened upon 

 each peduncle ; but on the cultivated tree a 

 great part of the flowers are abortive , and 

 the green fruit is cast at every stage of its 

 growth ; so that rarely more than one or two 

 germs upon a cluster arrive at maturity. 



It has been observed from early antiquity 

 that the produce of the Olive is alternate ; and 

 in France it is proverbially said to labour one

 The cause of this phenomenon will be men-
