plants later set out in rows in deep, rich, moderately 

 heavy loam with a good moisture-holding capacity. 

 Lime is excellent for the growth of this vegetable, but, 

 when it is absent, suitable manuring will bring large 

 returns. Disease is sure to attack the plant if the soil 

 is not well drained and rotation practiced, for cabbage 

 cannot profitably succeed itself or any other member of 

 its own family, such as common turnips, rutabagas, or 

 cauliflower. Liberal quantities of other than hog ma- 

 nure are beneficial if plowed in either in the fall or early 

 spring. In order to avoid the ravages of insects, among 

 which the cabbage has many enemies, cabbage must be 

 kept constantly growing by frequent cultivation. Cab- 

 bage may be left in the open until the temperature is 

 only a little above the freezing point, and when har- 

 vested must be put in a cool, dry place to prevent 

 decay, either in a cellar or in shallow ground pits. 



Fruits. - - The fruit of the plant is the ripened ovary, 

 or seed vessel, with its contents and whatever parts are 

 consolidated with it. A general classification into tree 

 fruits and small fruits will be found as convenient as 

 any, the latter including all fruits grown on small 

 shrubs, low plants, and recumbent or climbing vines. 

 The common tree fruits of the temperate regions are 

 the apple, pear, peach, plum, and cherry; of warmer 

 regions, the citrus fruits, orange, lemon, and grape- 

 fruit. The common small fruits are the strawberry, 

 raspberry, blackberry, the currant, the grape, the to- 

 mato, and the melons. 



Nuts are fruits with a hardened outer covering, or 

 shell. Few farmers pay any attention to their culture 

 except in the warmer regions where peanuts, almonds, 

 pecans, and the like are raised.
