64 FRUITS AND THEIR USES 



The grape crop of the world is commercially valuable, because of 

 the raisins and wine produced. Lemons, oranges, and grapefruit 

 have come in recent years to give a living to many people in this 

 country as well as in other parts of the world. The unfortunate city 

 of Messina was the center of the lemon industry for Italy. Figs, 

 olives, and dates are staple foods in the Mediterranean countries 

 and are sources of wealth to the people there, as are coconuts, 

 bananas, and many other fruits in tropical countries. 



Beverages and Condiments. The coffee and cocoa beans, 

 both products of tropical regions, form the basis of two very 

 important beverages of civilized man. Pepper, black and red, 

 mustard, allspice, nutmegs, cloves, and vanilla are all products 

 manufactured from various fruits or seeds of tropical plants.
