bined to grow pineapples and tropical guavas in western 

 Cuba. They will propagate the varieties of best grade by 

 grafting and growing from large cuttings. If systemati- 

 cally managed guava jelly and marmalade will be found 

 as a trade product wherever oranges are sold. Planting 

 the seeds where the trees are to stand and top -grafting or 

 crown-grafting them has given the best results in starting 

 plantations in Cuba by American growers. If the Indian 

 varieties are introduced the fruits also can be shipped from 

 Cuba as safely as the orange and at comparatively low 

 rates, as it is an enormous bearer. 



221. The Tomato. This South American fruit has in 

 recent years been developed in size and quality of fruit to 

 an extent that can never be equalled with the tree fruits. 

 Bailey says: "There is every reason to believe that the 

 tomato originally had a two- celled fruit, but in the course 

 of amelioration it has multiplied the locules or cells; it has 

 also modified the foliage and stature of the plant." 



During the past fifty years the large-fruited varieties 

 have been developed by crossing, selection, and culture, 

 and it has become a commercial fruit in canned form that 

 reaches about every part of Christendom. Over a large 

 part of west Europe it is grown under glass, but in 

 climates where the dent corns ripen it matures in the open 

 air. A large part of the immense output of canned 

 tomatoes is put up by canneries in the prairie States, and 

 of late in the Southern States and western New York. 

 In tropical climates it is a perennial, and we have seen it 

 in Cuba with stem six inches in diameter, from which fruit 

 was picked from the roof of two-story buildings. In west 

 Europe, where quite acid fruits are prized, it is used in ripe 

 state by many for eating and preferred to apples; but it is 

 mainly used everywhere for stewing or for table use in 

 fully ripened condition with cream and sugar.
